HPUX 11.31 MC-SG SGeRAC配置
HPUX 11.31 MC-SG SGeRAC配置
环境:
系统版本号 hp-unix 11.3v2 1503
serviceguard extension版本号 T1907
实施
1. 磁盘空间划分:
在磁盘阵列上划分两个磁盘空间。一个用于数据testvg。大小300G, 还有一个用于创建lockvg,大小为1G。
2. 改动/创建MC-SG:
首先,停止并删除现有Cluster(假设有的话):
hbyxdb1:root />cmhaltcl –v –f
hbyxdb1:root />cmdeleteconf
确认删除。这样就会保留原有的配置文件。而把二进制文件删除。
假设是新安装机器。则不用这一步。
改动MC/SG配置:
2.1 配置网络、磁盘相关部分:
vi /.rhosts---------两个主机都作
hbyxdb1 root
hbyxdb2 root
hbyxdb1-priv root
hbyxdb2-priv root
hbyxdb1-hb root
hbyxdb2-hb root
hbyxdb1-vip root
hbyxdb2-vip root
vi /etc/hosts---------两个主机都作
#public IP
10.109.4.129 hbyxdb1
10.109.4.130 hbyxdb2
#db_priv
10.109.5.65 hbyxdb1-priv
10.109.5.66 hbyxdb2-priv
#MC_HB
10.109.5.67 hbyxdb1-hb
10.109.5.68 hbyxdb2-hb
#rac_vip
10.109.4.131 hbyxdb1-vip
10.109.4.132 hbyxdb2-vip
使用nslookup检查配置的正确性:
Nslookup hbyxdb1
Nslookup hbyxdb2
Nslookup 10.109.4.129等。
从nodedb1上拷贝到nodedb2:
cp /.rhosts /etc/hosts.equiv
rcp /etc/hosts.equiv hbyxdb2:/etc/hosts.equiv
2.2 创建数据卷组和lockvg (/dev/disk/disk6006),事实上也能够直接用数据卷组作为lock vg.
首先创建数据卷组testvg(/dev/rdisk/disk6000):
hbyxdb1:root />pvcreate /dev/rdisk/disk6006
hbyxdb1:root />mkdir /dev/testvg
hbyxdb1:root />mknod /dev/testvg/group c 64 0x020000
hbyxdb1:root />vgcreate /dev/testvg /dev/disk/disk6006
Volume group "/dev/testvg" has been successfully created.
Volume Group configuration for /dev/testvg has been saved in /etc/lvmconf/testvg.conf
将testvg的map导出到/tmp下:
hbyxdb1:root />vgexport -p -v -s -m /tmp/testvg.map /dev/testvg
将testvg导入到hbyxdb2上:
hbyxdb1:root />cd /tmp
hbyxdb1:root />rcp /tmp/testvg.map hbyxdb2:/tmp/testvg.map
hbyxdb2:root />mkdir /dev/testvg
hbyxdb2:root />mknod /dev/testvg/group c 64 0x020000
hbyxdb2:root />vgimport -s -v -m /tmp/testvg.map /dev/testvg
Beginning the import process on Volume Group "/dev/testvg".
vgimport: Volume group "/dev/vgora" has been successfully created.
Please remember to take a backup using the vgcfgbackup command after activating the volume group.
然后在hbyxdb1上创建lockvg:
hbyxdb1:root />mkdir /dev/lockvg
hbyxdb1:root />mknod /dev/lockvg/group c 64 0x010000
hbyxdb1:root />vgcreate /dev/lockvg /dev/disk/disk6006
Volume group "/dev/lockvg" has been successfully created.
Volume Group configuration for /dev/lockvg has been saved in /etc/lvmconf/lockvg.conf
也导入到hbyxdb2上:
hbyxdb1:root />vgexport -p -v -s –m /tmp/lockvg.map /dev/lockvg
hbyxdb1:root /> cd /tmp
hbyxdb1:root />rcp /tmp/lockvg.map hbyxdb2:/tmp/lockvg.map .
hbyxdb2:root />mkdir /dev/lockvg
hbyxdb2:root />mknod /dev/lockvg/group c 64 0x010000
hbyxdb2:root />vgimport -s -v -m /tmp/lockvg.map /dev/lockvg
检查两边的/etc/lvmtab ,保证物理磁盘是一致的。假设不一致,能够使用lockvg.map在两边都导入一遍。
2.3 改动參数文件:
vi /etc/lvmrc---------两个主机都作。确保机器启动时不会激活共享卷组。
lockvg实际上不用激活就可以使用。
AUTO_VG_ACTIVE=0
假设要Cluster自己主动启动:
vi /etc/rc.config.d/cmcluster---------两个主机都作(这个文件默觉得仅仅读,能够chmod 755 更改文件读写权限)
AUTOSTART_CMCLD=1
2.4 在hbyxdb1 创立集群配置文件
#cmquerycl -n hbyxdb1 -n hbyxdb2 -v -C /etc/cmcluster/cluster.ascii
Number of configured IPv6 interfaces found: 0.

# ********* HIGH AVAILABILITY CLUSTER CONFIGURATION FILE ***************
# ***** For complete details about cluster parameters and how to *******
# ***** set them, consult the Serviceguard manual. *********************
# **********************************************************************
# Enter a name for this cluster. This name will be used to identify the
# cluster when viewing or manipulating it.
CLUSTER_NAME hbyxdb_cluster #(配置集群名字)
# The HOSTNAME_ADDRESS_FAMILY parameter specifies the Internet Protocol address
# family to which Serviceguard will attempt to resolve cluster node names and
# quorum server host names.
# If the parameter is set to IPV4, Serviceguard will attempt to resolve the names
# to IPv4 addresses only. This is the default value.
# If the parameter is set to IPV6, Serviceguard will attempt to resolve the names
# to IPv6 addresses only. No IPv4 addresses need be configured on the system or
# listed in the /etc/hosts file except for IPv4 loopback address.
# If the parameter is set to ANY, Serviceguard will attempt to resolve the names
# to both IPv4 and IPv6 addresses. The /etc/hosts file on each node must contain
# entries for all IPv4 and IPv6 addresses used throughout the cluster including
# all STATIONARY_IP and HEARTBEAT_IP addresses as well as any other addresses
HOSTNAME_ADDRESS_FAMILY IPV4
# Cluster Lock Parameters
# The cluster lock is used as a tie-breaker for situations
# in which a running cluster fails, and then two equal-sized
# sub-clusters are both trying to form a new cluster. The
# cluster lock may be configured using only one of the
# following alternatives on a cluster:
# the LVM lock disk
# the lock LUN
# the quorom server
#
#
# Consider the following when configuring a cluster.
# For a two-node cluster, you must use a cluster lock. For
# a cluster of three or four nodes, a cluster lock is strongly
# recommended. For a cluster of more than four nodes, a
# cluster lock is recommended. If you decide to configure
# a lock for a cluster of more than four nodes, it must be
# a quorum server.
# Lock Disk Parameters. Use the FIRST_CLUSTER_LOCK_VG and
# FIRST_CLUSTER_LOCK_PV parameters to define a lock disk.
# The FIRST_CLUSTER_LOCK_VG is the LVM volume group that
# holds the cluster lock. This volume group should not be
# used by any other cluster as a cluster lock device.
# LUN lock disk parameters. Use the CLUSTER_LOCK_LUN parameter
# to define the device on a per node basis. The device may only
# be used for this purpose and by only a single cluster.
#
# Example for a FC storage array cluster disk
# CLUSTER_LOCK_LUN /dev/dsk/c1t2d3s1
# For 11.31 and later versions of HP-UX with cluster device files
# CLUSTER_LOCK_LUN /dev/cdisk/disk22
# For 11.31 and later versions of HP-UX without cluster device files
# CLUSTER_LOCK_LUN /dev/disk/disk4_p2
# Quorum Server Parameters. Use the QS_HOST, QS_ADDR, QS_POLLING_INTERVAL,
# and QS_TIMEOUT_EXTENSION parameters to define a quorum server. The QS_HOST
# and QS_ADDR are either the host name or IP address of the system that is
# running the quorum server process. More than one IP address can be
# configured for the quorum server. When one subnet fails, Serviceguard
# uses the next available subnet to communicate with the quorum server.
# QS_HOST is used to specify the quorum server and QS_ADDR can be used to
# specify additional IP addresses for the quorum server. The QS_HOST entry
# must be specified (only once) before any other QS parameters. Only
# one QS_ADDR entry is used to specify the additional IP address.
# Both QS_HOST and QS_ADDR should not resolve to the same IP address.
# Otherwise cluster configuration will fail. All subnets must be up
# when you use cmapplyconf and cmquerycl to configure the cluster.
# The QS_POLLING_INTERVAL is the interval (in microseconds) at which
# Serviceguard checks to sure the quorum server is running.
# The optional QS_TIMEOUT_EXTENSION (in microseconds) is used to increase
# the time allocated for quorum server response. The default quorum
# server timeout is calculated primarily from MEMBER_TIMEOUT parameter.
# For cluster of up to 4 nodes it is 0.2*MEMBER_TIMEOUT. It increases
# as number of nodes increases and reaches to 0.5*MEMBER_TIMEOUT for
# 16 nodes
#
# If quorum server is configured on busy network or if quorum server
# polling is experiencing timeouts (syslog messages) or if quorum server
# is used for large number of clusters, such default time (as mentioned
# above) might not be sufficient. In such cases this paramter should be
# use to provide more time for quorum server.
# Also this parameter deserves more consideration if small values
# for MEMBER_TIMEOUT is used.
#
# The value of QS_TIMEOUT_EXTENSION will directly effect the amount of
# time it takes for cluster reformation in the event of node failure. For
# example, if QS_TIMEOUT_EXTENSION is set to 10 seconds, the cluster
# reformation will take 10 seconds longer than if the QS_TIMEOUT_EXTENSION
# was set to 0. This delay applies even if there is no delay incontacting
# the Quorum Server.#
# The recommended value for QS_TIMEOUT_EXTENSION is 0 (the default value),
# and the maximum supported value is 300000000 (5 minutes).
#
# For example, to configure a quorum server running on node "qs_host"
# with the additional IP address "qs_addr" and with 120 seconds for the
# QS_POLLING_INTERVAL and to add 2 seconds to the system assigned value
# for the quorum server timeout, enter
#
# QS_HOST qs_host
# QS_ADDR qs_addr
# QS_POLLING_INTERVAL 120000000
# QS_TIMEOUT_EXTENSION 2000000
FIRST_CLUSTER_LOCK_VG /dev/lockvg #(配置仲裁盘)
# Definition of nodes in the cluster.
# Repeat node definitions as necessary for additional nodes.
# NODE_NAME is the specified nodename in the cluster.
# It must match the hostname and both cannot contain full domain name.
# Each NETWORK_INTERFACE, if configured with IPv4 address,
# must have ONLY one IPv4 address entry with it which could
# be either HEARTBEAT_IP or STATIONARY_IP.
# Each NETWORK_INTERFACE, if configured with IPv6 address(es)
# can have multiple IPv6 address entries(up to a maximum of 2,
# only one IPv6 address entry belonging to site-local scope
# and only one belonging to global scope) which could be
# either HEARTBEAT_IP or STATIONARY_IP.
# Note: This configuration contains IPv4 STATIONARY_IP or HEARTBEAT_IP
# addresses. To obtain an IPv6-only cluster on supported platforms,
# comment out any IPv4 STATIONARY_IPs or HEARTBEAT_IPs.
# If this leaves any NETWORK_INTERFACE without any STATIONARY_IP or
# HEARTBEAT_IP, comment out the NETWORK_INTERFACE as well.
# Modify the resulting configuration as necessary to meet the
# hearbeat requirements and recommendations for a Serviceguard
# configuration. These are spelled out in chapter 4 of the Managing
# Serviceguard manual.
#
# Node capacity parameters. Use tne CAPACITY_NAME and CAPACITY_VALUE
# parameters to define a capacity for the node. Node capacities correspond to
# package weights; node capacity is checked against the corresponding
# package weight to determine if the package can run on that node.
#
# CAPACITY_NAME specifies a name for the capacity.
# The capacity name can be any string that starts and ends with an
# alphanumeric character, and otherwise contains only alphanumeric characters,
# dot (.), dash (-), or underscore (_). Maximum string
# length is 39 characters. Duplicate capacity names are not allowed.
#
# CAPACITY_VALUE specifies a value for the CAPACITY_NAME that precedes
# it. This is a floating point value between 0 and 1000000. Capacity values
# are arbitrary as far as Serviceguard is concerned; they have meaning only in
# relation to the corresponding package weights.
# Node capacity definition is optional, but if CAPACITY_NAME is specified,
# CAPACITY_VALUE must also be specified; CAPACITY_NAME must come first.
# To specify more than one capacity, repeat this process for each capacity.
# NOTE: If a given capacity is not defined for a node, Serviceguard assumes
# that capacity is infinite on that node. For example, if pkgA, pkgB, and pkgC
# each specify a weight of 1000000 for WEIGHT_NAME "memory", and CAPACITY_NAME
# "memory" is not defined for node1, then all three packages are eligible
# to run at the same time on node1, assuming all other requirements are met.
#
# Cmapplyconf will fail if any node defines a capacity and
# any package has min_package_node as the failover policy or
# has automatic as the failback policy.
# You can define a maximum of 4 capacities.
#
# NOTE: Serviceguard supports a capacity with the reserved name
# "package_limit". This can be used to limit the number of packages
# that can run on a node. If you use "package_limit", you cannot
# define any other capacities for this cluster, and the default
# weight for all packages is 1.
#
# Example:
# CAPACITY_NAME package_limit
# CAPACITY_VALUE 4
#
# This allows a maximum of four packages to run on this node,
# assuming each has the default weight of one.
#
# For all capacities other than "package_limit", the default weight for
# all packages is zero

# Cluster Timing Parameters (microseconds).
# The MEMBER_TIMEOUT parameter defaults to 14000000 (14 seconds).
# If a heartbeat is not received from a node within this time, it is

# A value of 10 to 25 seconds is appropriate for most installations.
# For installations in which the highest priority is to reform the cluster
# as fast as possible, a setting of as low as 3 seconds is possible.
# When a single heartbeat network with standby interfaces is configured,
# MEMBER_TIMEOUT cannot be set below 14 seconds if the network interface
# type is Ethernet, or 22 seconds if the network interface type is
# InfiniBand (HP-UX only).
# Note that a system hang or network load spike whose duration exceeds
# MEMBER_TIMEOUT will result in one or more node failures.
# The maximum value recommended for MEMBER_TIMEOUT is 60000000

# Network Monitor Configuration Parameters.
# The NETWORK_FAILURE_DETECTION parameter determines how LAN card failures are detected.

# IP Monitor Configuration Parameters.
# The following set of three parameters can be repeated as necessary.
# SUBNET is the subnet to be configured whether or not to be monitored

# IP_MONITOR is set to ON if the subnet is to be monitored at IP layer.
# IP_MONITOR is set to OFF if the subnet is not to be monitored at IP layer.
# POLLING_TARGET is the IP address to which polling messages are sent
# from each network interface in the subnet.
# Each SUBNET can have multiple polling targets, so multiple
# POLLING_TARGET entries can be specified. If no POLLING_TARGET is
# specified, peer interfaces in the subnet will be polling targets for each other.
# Only subnets with a gateway that is configured to accept

MAX_CONFIGURED_PACKAGES 300
# Optional package default weight parameters. Use WEIGHT_NAME and
# WEIGHT_DEFAULT parameters to define a default value for this weight
# for all packages except system multi-node packages.
# Package weights correspond to node capacities; node capacity
# is checked against the corresponding package weight to determine
# if the package can run on that node.
#
# WEIGHT_NAME
# specifies a name for a weight that corresponds to a
# capacity specified earlier in this file. Weight is defined for
# a package, whereas capacity is defined for a node. For any given
# weight/capacity pair, WEIGHT_NAME, CAPACITY_NAME (and weight_name
# in the package configuration file) must be the same. The rules for
# forming all three are the same. See the discussion of the capacity
# parameters earlier in this file.
# NOTE: A weight (WEIGHT_NAME/WEIGHT_DEFAULT) has no meaning on a node
# unless a corresponding capacity (CAPACITY_NAME/CAPACITY_VALUE) is
# defined for that node.
# For example, if CAPACITY_NAME "memory" is not defined for
# node1, then node1's "memory" capacity is assumed to be infinite.
# Now even if pkgA, pkgB, and pkgC each specify the maximum weight
# of 1000000 for WEIGHT_NAME "memory", all three packages are eligible
# to run at the same time on node1, assuming all other requirements are met.
#
# WEIGHT_DEFAULT specifies a default weight for this WEIGHT_NAME.
# This is a floating point value between 0 and 1000000.
# Package weight default values are arbitrary as far as Serviceguard is
# concerned; they have meaning only in relation to the corresponding node capacities.
#
# The package weight default parameters are optional. If they are not
# specified, a default value of zero will be assumed. If defined,
# WEIGHT_DEFAULT must follow WEIGHT_NAME. To specify more than one package
# weight, repeat this process for each weight.
# Note: for the reserved weight "package_limit", the default weight is
# always one. This default cannot be changed in the cluster configuration file,
# but it can be overriden in the package configuration file.
#
# For any given package and WEIGHT_NAME, you can override the WEIGHT_DEFAULT
# set here by setting weight_value to a different value for the corresponding
# weight_name in the package configuration file.
#
# Cmapplyconf will fail if you define a default for a weight and no node
# in the cluster specifies a capacity of the same name.
# You can define a maximum of 4 weight defaults
#
# Example: The following example defines a default for "processor" weight
# of 0.1 for the package:
#
# WEIGHT_NAME processor
# WEIGHT_DEFAULT 0.1
#
# WEIGHT_NAME
# WEIGHT_DEFAULT
# Access Control Policy Parameters.
#
# Three entries set the access control policy for the cluster:
# First line must be USER_NAME, second USER_HOST, and third USER_ROLE.
# Enter a value after each.
#
# 1. USER_NAME can either be ANY_USER, or a maximum of
# 8 login names from the /etc/passwd file on user host.
# The following special characters are NOT supported for USER_NAME
# ' ', '/', '\', '*'
# 2. USER_HOST is where the user can issue Serviceguard commands.
# If using Serviceguard Manager, it is the COM server.
# Choose one of these three values: ANY_SERVICEGUARD_NODE, or
# (any) CLUSTER_MEMBER_NODE, or a specific node. For node,
# use the official hostname from domain name server, and not
# an IP addresses or fully qualified name.
# 3. USER_ROLE must be one of these three values:
# * MONITOR: read-only capabilities for the cluster and packages
# * PACKAGE_ADMIN: MONITOR, plus administrative commands for packages
# in the cluster
# * FULL_ADMIN: MONITOR and PACKAGE_ADMIN plus the administrative
# commands for the cluster.
#
# Access control policy does not set a role for configuration
# capability. To configure, a user must log on to one of the
# cluster's nodes as root (UID=0). Access control
# policy cannot limit root users' access.
#
# MONITOR and FULL_ADMIN can only be set in the cluster configuration file,
# and they apply to the entire cluster. PACKAGE_ADMIN can be set in the
# cluster or a package configuration file. If set in the cluster
# configuration file, PACKAGE_ADMIN applies to all configured packages.
# If set in a package configuration file, PACKAGE_ADMIN applies to that package only.
#
# MONITOR is set by default in a new cluster configuration as of Serviceguard
# release A.11.19.00. This is to support cluster discovery from other HP
# Administration products such as Systems Insight Manager (HP SIM) and
# Distributed Systems Administration (DSAU) tools. Removing MONITOR is allowed
# as an online configuration change within Serviceguard. However removing MONITOR
# will break cluster management for HP SIM and HP VSE products
#
# Conflicting or redundant policies will cause an error while applying
# the configuration, and stop the process. The maximum number of access
# policies that can be configured in the cluster is 200.
#
# Example: to configure a role for user john from node noir to
# administer a cluster and all its packages, enter:
# USER_NAME john
# USER_HOST noir
# USER_ROLE FULL_ADMI
USER_NAME ANY_USER
USER_HOST ANY_SERVICEGUARD_NODE
USER_ROLE MONITOR

#
# "PACKAGE_NAME" is the name that is used to identify the package.
# This name will be used to identify the package when viewing or
# manipulating it. Package names must be unique within a cluster.
# Legal values for PACKAGE_NAME:
# Any string that starts and ends with an alphanumeric character, and
# contains only alphanumeric characters, dot(.), dash(-), or underscore(_)
# in between.
# Maximum length is 39 characters.
#
PACKAGE_NAME orapkg
# "PACKAGE_TYPE" is the type of package.
#
# The PACKAGE_TYPE attribute specifies the desired behavior for this
# package. Legal values and their meaning are described below:
#
# FAILOVER package runs on one node at a time and if a failure
# occurs it can switch to an alternate node.
#
# MULTI_NODE package runs on multiple nodes at the same time and
# can be independently started and halted on
# individual nodes. Failures of package components such
# as services, EMS resources or subnets, will cause
# the package to be halted only on the node on which the
# failure occurred. Relocatable IP addresses cannot be
# assigned to "multi_node" packages.
#
# SYSTEM_MULTI_NODE
# package runs on all cluster nodes at the same time.
# It cannot be started and halted on individual nodes.
# Both "NODE_FAIL_FAST_ENABLED" and "AUTO_RUN"
# must be set to "YES" for this type of package. All
# "SERVICES" must have "SERVICE_FAIL_FAST_ENABLED" set
# to "YES". SYSTEM_MULTI_NODE packages are only
# supported for use by applications provided by Hewlett-Packard.
#
# Since "MULTI_NODE" and "SYSTEM_MULTI_NODE" packages can run on more
# than one node at a time and do not failover in the event of a
# package failure, the following parameters cannot be
# specified when configuring packages of these types:
#
# FAILOVER_POLICY
# FAILBACK_POLICY
#
# Since an IP address cannot be assigned to more than one node at
# a time, relocatable IP addresses cannot be assigned to
# "MULTI_NODE" packages. If volume groups are used in a
# "MULTI_NODE" package, they must be activated in shared mode,
# leaving the application responsible for data integrity.
# Shared access requires a shared volume manager.
# The default value for "PACKAGE_TYPE" is "FAILOVER".
# Legal values for PACKAGE_TYPE: FAILOVER, MULTI_NODE, SYSTEM_MULTI_NODE.
PACKAGE_TYPE MULTI_NODE
#(由于oracle为RAC,MC-SG仅仅是挂载共享磁盘,共享磁盘并不切换。也没有IP切换,所以该包仅仅是在指定的机器上执行就可以。不用切换,故用 MULTI_NODE 方式)
# "NODE_NAME" specified which nodes this package can run on.
# Enter the names of the nodes configured to run this package, repeat
# this line for each cluster member node configured to run this package.
# NOTE: The order in which the nodes are specified here determines the order of priority when Serviceguard is deciding where to run the package.
# Example : NODE_NAME first_priority_node
# NODE_NAME second_priority_node
# If all nodes in the cluster can run the package, and order is not important, specify "NODE_NAME *".
# Example : NODE_NAME *
# Legal values for NODE_NAME:
# "*", or any node name in the cluster.
# Node name is any string that starts and ends with an alphanumeric character, and contains only alphanumeric characters, dot(.), dash(-), or underscore(_) in between.
# Maximum name length is 39 characters.

# "AUTO_RUN" defines whether the package is to be started when the cluster is started, and if it will fail over automatically.
# Possible values are "YES" and "NO".
# The default for "AUTO_RUN" is "YES", meaning that the package will be automatically started when the cluster is started, and that,
# in the event of a failure the package will be started on an adoptive node. If "AUTO_RUN" is "NO",
# the package is not started when the cluster is started, and must be started with the cmrunpkg command.
# "AUTO_RUN" replaces "PKG_SWITCHING_ENABLED".
# Legal values for AUTO_RUN: YES, NO.
AUTO_RUN YES
# "NODE_FAIL_FAST_ENABLED" will cause node to fail if package fails.
# Possible values are "YES" and "NO".
# The default for "NODE_FAIL_FAST_ENABLED" is "NO". In the event of
# failure, if "NODE_FAIL_FAST_ENABLED" is set to "YES", Serviceguard
# will halt the node on which the package is running. All
# "SYSTEM_MULTI_NODE" packages must have "NODE_FAIL_FAST_ENABLED" set to "YES".
# Legal values for NODE_FAIL_FAST_ENABLED: YES, NO.
NODE_FAIL_FAST_ENABLED NO
# "RUN_SCRIPT" is the script that starts a package.
# "HALT_SCRIPT" is the script that stops a package.
# Enter the complete path for the run and halt scripts. The scripts must
# be located in directory with "cmcluster" in the path name. In most cases
# the run script and halt script specified here will be the same script,
# the package control script generated by the cmmakepkg command. This
# control script handles the run(ning) and halt(ing) of the package.
# Legal values for RUN_SCRIPT:
# Full path name for the run script with "cmcluster" in the path name.
# The maximum length for the path name is MAXPATHLEN characters long.
RUN_SCRIPT /etc/cmcluster/clusterpkg/cluster.cntl
# Legal values for HALT_SCRIPT:
# Full path name for the halt script with "cmcluster" in the path name.
# The maximum length for path name MAXPATHLEN characters long.
HALT_SCRIPT /etc/cmcluster/clusterpkg/cluster.cntl
# "RUN_SCRIPT_TIMEOUT" is the number of seconds allowed for the package to start.
# "HALT_SCRIPT_TIMEOUT" is the number of seconds allowed for the package to halt.
# If the start or halt function has not completed in the specified
# number of seconds, the function will be terminated. The default for
# each script timeout is "NO_TIMEOUT". Adjust the timeouts as necessary
# to permit full execution of each function.
# Note: The "HALT_SCRIPT_TIMEOUT" should be greater than the sum of

# SUCCESSOR_HALT_TIMEOUT limits the amount of time
# Serviceguard waits for successors of this package to
# halt, before running the halt script of this package.
# This is an optional parameter.
# Permissible values are 0 - 4294 (specifying the maximum
# number of seconds Serviceguard will wait).
# The default value is "NO_TIMEOUT", which means Serviceguard
# will wait for as long as it takes for the successor package to halt.
# The timeout of 0 indicates, that this package will halt without
# waiting for successors packages to halt
# Example: \n"
# SUCCESSOR_HALT_TIMEOUT NO_TIMEOUT

# Legal values for SUCCESSOR_HALT_TIMEOUT: NO_TIMEOUT, ( (value >= 0) && (value <= 4294) ).
SUCCESSOR_HALT_TIMEOUT NO_TIMEOUT
# "SCRIPT_LOG_FILE" is the full path name for the package control script
# log file. The maximum length of the path name is MAXPATHLEN characters long.
# If not set, the script output is sent to a file named by appending
# ".log" to the script path.
# Legal values for SCRIPT_LOG_FILE: <Any String>
#SCRIPT_LOG_FILE
# "FAILOVER_POLICY" is the policy to be applied when package fails.
# This policy will be used to select a node whenever the package needs
# to be started or restarted. The default policy is "CONFIGURED_NODE".
# This policy means Serviceguard will select nodes in priority order from the list of "NODE_NAME" entries.
# An alternative policy is "SITE_PREFERRED". This policy means
# that when selecting nodes from the list of "NODE_NAME" entries,
# Serviceguard will give priority to nodes that belong to the site the
# package last ran on, over those that belong to a different site. When
# all nodes belonging to the same site where the package last ran are
# unable to run the package, the package will automatically fail over to the other site.
# An alternative policy is "SITE_PREFERRED_MANUAL". This policy can
# be used only in a Metrocluster environment. This policy means
# that when selecting nodes from the list of "node_name" entries,
# Serviceguard selects a node that belongs to the site that the package
# last ran on. When all nodes belonging to the same site where the package
# last ran are unable to run the package, the package will not automatically
# fail over to the other site. In such situations, manual intervention is
# needed to start the package on either the same site or on another site.
# Another policy is "MIN_PACKAGE_NODE". This policy means
# Serviceguard will select from the list of "NODE_NAME" entries the
# node, which is running fewest packages when this package needs to start.
# Legal values for FAILOVER_POLICY: CONFIGURED_NODE, MIN_PACKAGE_NODE, SITE_PREFERRED, SITE_PREFERRED_MANUAL.
FAILOVER_POLICY CONFIGURED_NODE
#(由于oracle为RAC,MC-SG仅仅是挂载共享磁盘,共享磁盘并不切换,也没有IP切换。所以该包仅仅是在指定的机器上执行就可以,不用切换)
# "FAILBACK_POLICY" is the action to take when a package is not running on its primary node.
# This policy will be used to determine what action to take when a
# package is not running on its primary node and its primary node is
# capable of running the package. The default policy is "MANUAL". The
# "MANUAL" policy means no attempt will be made to move the package back
# to its primary node when it is running on an adoptive node.
# The alternative policy is "AUTOMATIC". This policy means Serviceguard
# will attempt to move the package back to its primary node as soon as
# the primary node is capable of running the package.
# Legal values for FAILBACK_POLICY: MANUAL, AUTOMATIC.
FAILBACK_POLICY MANUAL
# "PRIORITY" specifies the PRIORITY of the package.
# This is an optional parameter. Valid values are a number between
# 1 and 3000 or NO_PRIORITY. Default is NO_PRIORITY.
# A smaller number indicates higher priority. A package with a
# numerical priority has higher priority than a package with NO_PRIORITY.
# If a number is specified, it must be unique in the cluster.
# To help assign unique priorities, HP recommends you use
# priorities in increments of 10. This will allow you
# to add new packages without having to reassign priorities.
# Multi-node and System multi node packages cannot be assigned a priority.
# This parameter is used only when a weight has been defined for a package,
# a package depends on other packages,
# or other packages depend on this package, but can be specified even
# when no weights or dependencies have yet been configured.
# If priority is not configured, the package is assigned the default
# priority value, NO_PRIORITY.
# Serviceguard gives preference to running the higher priority package.
# This means that, if necessary, Serviceguard will halt a package (or
# halt and restart on anther node) in order to run a higher priority
# package. The reason may be:
# * the node's capacity would otherwise be exceeded
# * there is a direct or indirect dependency between the lower and
# higher priority packages.
# For example, suppose package pkg1 depends on package pkg2
# to be up on the same node, both have package switching enabled
# and both are currently up on node node1. If pkg1 needs to
# fail over to node2, it will also need pkg2 to move to node2.
# If pkg1 has higher priority than pkg2, it can force pkg2 to
# move to node2. Otherwise, pkg1 cannot fail over because pkg2 is
# running on node1.
# Examples of package priorities and failover results:
# pkg1 priority pkg2 priority results
# 10 20 pkg1 is higher; fails over
# 20 10 pkg1 is lower; will not fail over
# any number NO_PRIORITY pkg1 is higher; fails over
# NO_PRIORITY NO_PRIORITY equal priority; will not fail over
# NO_PRIORITY any number pkg1 is lower; will not fail over
# Legal values for PRIORITY: NO_PRIORITY, ( (value >= 1) && (value <= 3000) ).
PRIORITY NO_PRIORITY
# The package dependency parameters are "DEPENDENCY_NAME",
# "DEPENDENCY_CONDITION" and "DEPENDENCY_LOCATION".
# Dependencies are used to describe the relationship between two packages.
# To define a dependency, "DEPENDENCY_NAME" and "DEPENDENCY_CONDITION"
# are required and "DEPENDENCY_LOCATION is optional.
# "DEPENDENCY_NAME" must be a unique identifier for the dependency.
# "DEPENDENCY_CONDITION" describes what must be true for
# the dependency to be satisfied.
# The syntax is: <package name> = <package status>
# The valid values for <package status> are "up" or "down".
# "up" means that this package requires the package identified
# by "PACKAGE_NAME" to be up (status reported by cmviewcl is "up").
# If "up" is specified, the dependency rules are as follows:
# * A multi-node package can depend only on another multi-
# node or system multi-node package.
# * A failover package whose FAILOVER_POLICY is
# MIN_PACKAGE_NODE can depend only on a multi-node or
# system multi-node package.
# * A failover package whose FAILOVER_POLICY is
# CONFIGURED_NODE can depend on a multi-node or system
# multi-node package, or another failover package whose
# FAILOVER_POLICY is CONFIGURED_NODE.
# "down" means that this package requires the package
# identified by "package name" to be down (status reported by cmviewcl is "down"). This is known as an exclusion dependency.
# This means that only one of these packages can be running at any given time.
# If "down" value is specified, the exclusion dependency must be mutual; that is, if pkgA depends on pkgB to be down, pkgB must
# also depend on pkgA to be down.
# This means that in order to create an exclusion dependency between two packages, you must apply both packages to the
# cluster configuration at the same time.
# An exclusion dependency is allowed only between failover
# packages with configured_node as failover policy, and at least one of the packages must specify a priority.
# "DEPENDENCY_LOCATION"
# This describes where the condition must be satisfied.
# This parameter is optional. If it is not specified, the default value "same_node" will be used.
# The possible values for this attribute depend on the
# dependency condition.
# If an "up" dependency is specified, the possible values are "same_node", "any_node", and "different_node".
# "same_node" means the dependency must be satisifed on the same node.
# "any_node" means the dependency can be satisified on
# any node in the cluster.
# "different_node" means the dependency must be satisfied
# on a node other than the dependent package's node.
# If a "down" dependency is specified, the possible values are "same_node" and "all_nodes".
# "same_node" means the package depended on must be down on the same node.
# "all_nodes" means the package depended on must be down on all nodes in the cluster.
# NOTE:
# Within a package, you cannot specifiy more than one dependency on the
# same package. For example, pkg1 cannot have one same_node and one any_node dependency on pkg2.
# When a package requires that another package be up and the
# DEPENDENCY_LOCATION is any_node or different_node, the priority of the
# the package depended on must be higher or equal to the dependent
# package and its dependents. For example, if pkg1 has a same_node
# dependency on pkg2 and pkg2 has an any_node dependency on pkg3,
# the priority of pkg3 must be higher or equal to the priority of pkg1 and pkg2.
# In a CFS cluster, the dependencies among the mount point, disk group,
# and system multi-node packages are automatically created by the commands that construct those packages.
# Example 1 : To specify a "same_node" dependency between pkg1 and pkg2:
# pkg1's ascii configuration file:
# DEPENDENCY_NAME pkg2_dep
# DEPENDENCY_CONDITION pkg2 = up
# DEPENDENCY_LOCATION same_node
# Example 2 : To specify a "same_node" exclusion dependency between pkg1 and pkg2:
# pkg1's ascii configuration file:
# DEPENDENCY_NAME pkg2_dep
# DEPENDENCY_CONDITION pkg2 = down
# DEPENDENCY_LOCATION same_node
# pkg2's ascii configuration file:
# DEPENDENCY_NAME pkg1_dep
# DEPENDENCY_CONDITION pkg1 = down
# DEPENDENCY_LOCATION same_node
# Note that pkg1 and pkg2 must be applied at the same time.
# Legal values for DEPENDENCY_NAME:
# Any string that starts and ends with an alphanumeric character, and
# contains only alphanumeric characters, dot(.), dash(-), or underscore(_) in the middle.
# Maximum string length is 39 characters.
# Legal values for DEPENDENCY_CONDITION: <Any String>
# Legal values for DEPENDENCY_LOCATION: same_node, any_node, different_node, all_nodes.
#DEPENDENCY_NAME
#DEPENDENCY_CONDITION
#DEPENDENCY_LOCATION
# The package weight parameters are the "WEIGHT_NAME" and "WEIGHT_VALUE".
# These optional attributes provide additional data which the
# Serviceguard package manager uses when selecting a node on which to
# place the package. As with all attribute names, they are case insensitive.
# A package can use this mechanism to define up to four arbitrary
# weight names with corresponding values that are meant to represent
# the runtime resource consumption of the package. In the cluster
# configuration file, you configure capacity limits for the named
# weights on the cluster nodes. During package placement,
# the package manager will ensure the total value of any given named
# weight does not exceed the capacity limit configured for the node.
# The "WEIGHT_NAME" is string of up to 39 characters.
# The "WEIGHT_VALUE" specifies a value for the named weight that
# precedes it. This is an unsigned floating point value between 0 and
# 1000000 with at most three digits after the decimal point.
# If "WEIGHT_NAME" is specified, "WEIGHT_VALUE" must also be specified
# and "WEIGHT_NAME" must come first. To specifiy more than one weight, repeat this process.
# You can define weights either individually within each
# package configuration file, or by means of a default value
# in the cluster configuration file that applies to all configured
# packages (except system multi-node packages). If a particular
# weight name is defined in both the cluster and package configuration
# files, the value specified in the package configuration file takes
# precedence. This allows you to set an overall default, but to override it for a particular package.
# For example, if you specify WEIGHT_NAME "memory" with WEIGHT_DEFAULT
# 1000 in the cluster configuration file, and you do not specify a weight
# value for "memory" in the package configuration file for pkgA, pkgA's
# "memory" weight will be 1000. If you define a weight value of 2000 for
# "memory" in the configuration file for pkgA, pkgA's "memory" weight will be 2000.
# If no WEIGHT_NAME/WEIGHT_DEFAULT value is specified in the cluster
# configuration file for a given CAPACITY, and WEIGHT_NAME and WEIGHT_VALUE
# are not specified in this package configuration file for that CAPACITY,
# then the WEIGHT_VALUE for this package is set to zero or one depending
# on the capacity name. If the capacity name is the reserved capacity
# "package_limit", the WEIGHT_VALUE for this package is set to one;
# otherwise, the WEIGHT_VALUE is set to zero.
# For example, if you specify CAPACITY "memory" and do not specify
# a WEIGHT_DEFAULT for "memory" in the cluster configuration file,
# and do not specify weight "memory" in the package configuration
# file for pkgA, then pkgA's "memory" weight will be zero.
# Note that cmapplyconf will fail if you define a weight in the package
# configuration file and no node in the cluster configuration file
# specifies a capacity of the same name.
# Weight can be assigned only to multi-node packages, and failover packages
# with CONFIGURED_NODE as the FAILOVER_POLICY and MANUAL as the FAILBACK POLICY.
# For more information on how to configure default weights and
# node capacities, see the cmquerycl man page, the cluster configuration
# template file, and the Managing Serviceguard manual.
# Example :
# WEIGHT_NAME package_limit
# WEIGHT_VALUE 10
# This overrides the default value of 1 and sets the weight for this
# package to 10
# Legal values for WEIGHT_NAME:
# Any string that starts and ends with an alphanumeric character, and
# contains only alphanumeric characters, dot(.), dash(-), or underscore(_)
# in the middle.
# Maximum string length is 39 characters.
# Legal values for WEIGHT_VALUE:
# Any unsigned floating point string. Only 3 digits after the decimal point
# are significant. Maximum string length is 11 characters.
#WEIGHT_NAME
#WEIGHT_VALUE
# "LOCAL_LAN_FAILOVER_ALLOWED" will allow LANs to be switched locally.
# Possible values are "YES" and "NO".
# The default for "LOCAL_LAN_FAILOVER_ALLOWED" is "YES". In the event of a
# failure, this permits the Serviceguard to switch LANs locally
# (transfer to a standby LAN card). Adjust as necessary.
# "LOCAL_LAN_FAILOVER_ALLOWED" replaces "NET_SWITCHING_ENABLED".
# Legal values for LOCAL_LAN_FAILOVER_ALLOWED: YES, NO.
LOCAL_LAN_FAILOVER_ALLOWED YES
# "MONITORED_SUBNET" specifies the addresses of subnets that are to be
# monitored for this package.
# Enter the network subnet name that is to be monitored for this package.
# Repeat this line as necessary for additional subnet names. If any of
# the subnets defined goes down, the package will be switched to another
# node that is configured for this package and has all the defined subnets available.
# "MONITORED_SUBNET" replaces "SUBNET".
# The MONITORED_SUBNET names can be IPv4 or IPv6, or a mix of both.
# Example :
# MONITORED_SUBNET 192.10.25.0 # (netmask=255.255.255.0)
# MONITORED_SUBNET 2001::/64 # (netmask=ffff:ffff:ffff:ffff::)
# MONITORED_SUBNET 2001:: # (netmask=ffff:ffff:ffff:ffff::)
# Legal values for MONITORED_SUBNET: <Any String>
# "MONITORED_SUBNET_ACCESS" defines how the MONITORED_SUBNET is
# configured in the cluster.
# MONITORED_SUBNET_ACCESS defines whether access to a MONITORED_SUBNET
# is configured on all of the nodes that can run this package, or only
# on some. Possible values are "PARTIAL" and "FULL". "PARTIAL" means
# that the MONITORED_SUBNET is expected to be configured on one or more
# of the nodes this package can run on, but not all. "FULL" means that
# the MONITORED_SUBNET is expected to be configured on all the nodes
# that this package can run on. "FULL" is the default. (Specifying
# "FULL" is equivalent to not specifying the monitored_subnet_access at all.)
# The MONITORED_SUBNET_ACCESS is defined per MONITORED_SUBNET entry.
# Example :
# MONITORED_SUBNET 192.10.25.0
# MONITORED_SUBNET_ACCESS PARTIAL # 192.10.25.0 is available on one
# or more nodes of the cluster, but not all.
# MONITORED_SUBNET 192.10.26.0 # no MONITORED_SUBNET_ACCESS entry,
# hence this subnet is available
# on all nodes of the cluster.
# MONITORED_SUBNET 2001::/64
# MONITORED_SUBNET_ACCESS FULL # 2001::/64 is available on all
# nodes of the cluster.
# Legal values for MONITORED_SUBNET_ACCESS: PARTIAL, FULL.
#MONITORED_SUBNET
#MONITORED_SUBNET_ACCESS
# "CLUSTER_INTERCONNECT_SUBNET" specifies subnets that are to be monitored for
# a SGERAC multi-node package.
# This parameter requires an IPV4 or IPV6 address. CLUSTER_INTERCONNECT_SUBNETs
# can be configured only for multi_node packages in SGeRAC configurations.
# Legal values for CLUSTER_INTERCONNECT_SUBNET: <Any String>
#CLUSTER_INTERCONNECT_SUBNET
# "SERVICE_NAME" is a long lived (daemon) executable which
# Serviceguard will monitor while the package is up.
# "SERVICE_NAME", "SERVICE_FAIL_FAST_ENABLED" and "SERVICE_HALT_TIMEOUT"
# specify a service for this package.
# The value for "SERVICE_FAIL_FAST_ENABLED" can be either "yes" or
# "no". The default is "no". If "SERVICE_FAIL_FAST_ENABLED" is set to
# "yes", and the service fails, Serviceguard will halt the node on which
# the service is running.
# "SERVICE_HALT_TIMEOUT" is a number of seconds. This timeout is used
# to determine the length of time the Serviceguard will wait for the
# service to halt before a SIGKILL signal is sent to force the
# termination of the service. In the event of a service halt,
# Serviceguard will first send a SIGTERM signal to terminate the
# service. If the service does not halt, Serviceguard will wait for the
# specified "SERVICE_HALT_TIMEOUT", then send the SIGKILL signal to
# force the service to terminate. This timeout value should be large
# enough to allow all cleanup processes associated with the service to
# complete. If the "SERVICE_HALT_TIMEOUT" is not specified, a zero
# timeout will be assumed, meaning the cluster software will not wait at
# all before sending the SIGKILL signal to halt the service.
# Example:
# SERVICE_NAME service_1a
# SERVICE_FAIL_FAST_ENABLED no
# SERVICE_HALT_TIMEOUT 300
# SERVICE_NAME service_1b
# SERVICE_FAIL_FAST_ENABLED no
# SERVICE_HALT_TIMEOUT 300
# SERVICE_NAME service_1c
# SERVICE_FAIL_FAST_ENABLED no
# SERVICE_HALT_TIMEOUT 300
# Note: No environmental variables will be passed to the service command, this
# includes the PATH variable. Absolute path names are required for the
# service command definition. Default shell is /usr/bin/sh.
# Legal values for SERVICE_NAME:
# Any string that starts and ends with an alphanumeric character, and
# contains only alphanumeric characters, dot(.), dash(-), or underscore(_) in between.
# Maximum string length is 39 characters.
# Legal values for SERVICE_FAIL_FAST_ENABLED: yes, no.
# Legal values for SERVICE_HALT_TIMEOUT: (value >= 0).

# Event Monitoring Service Resource Dependencies
# Event monitoring service resource dependencies are specified with the
# following parameters: "RESOURCE_NAME", "RESOURCE_POLLING_INTERVAL",
# "RESOURCE_START" and "RESOURCE_UP_VALUE".
# To define a package resource dependency, a "RESOURCE_NAME" line with
# a fully qualified resource path name, and one or more
# "RESOURCE_UP_VALUE" lines are required. "RESOURCE_POLLING_INTERVAL" and
# the "RESOURCE_START" are optional, and will default as described
# below if not specified.
# The "RESOURCE_POLLING_INTERVAL" indicates how often, in seconds, the
# resource is to be monitored. The default is 60 seconds.
# The "RESOURCE_START" option can be set to either "automatic" or "deferred".
# The default is "automatic". "automatic" means Serviceguard will
# start up resource monitoring for this resource automatically when the
# node starts up. If "deferred" is specified, Serviceguard will not
# attempt to start this resource at node start up. User
# should specify all the "deferred" resources in the package run script
# so that these "deferred" resources will be started up from the package
# run script during package run time.
# "RESOURCE_UP_VALUE" requires an operator and a value. This defines
# the resource 'UP' condition. The operators are =, !=, >, <, >=,
# and <=, depending on the type of value. Values can be string or
# numeric. If the type is string, then only = and != are valid
# operators. If the string contains white space, it must be enclosed
# in quotes. String values are case sensitive. For example,
# Resource is up when its value is
# --------------------------------
# RESOURCE_UP_VALUE = UP "UP"
# RESOURCE_UP_VALUE != DOWN Any value except "DOWN"
# RESOURCE_UP_VALUE = "On Course" "On Course"
#
# If the type is numeric, then it can specify a threshold, or a range to
# define a resource up condition. If it is a threshold, then any operator
# may be used. If a range is to be specified, then only > or >= may be used
# for the first operator, and only < or <= may be used for the second operator.
# For example,
# Resource is up when its value is
# --------------------------------
# RESOURCE_UP_VALUE = 5 5 (threshold)
# RESOURCE_UP_VALUE > 5.1 greater than 5.1 (threshold)
# RESOURCE_UP_VALUE > -5 and < 10 between -5 and 10 (range)
#
# Note that "and" is required between the lower limit and upper limit to
# specify a range. The upper limit must be greater than the lower
# limit. If "RESOURCE_UP_VALUE" is repeated within a "RESOURCE_NAME"
# block, then they are inclusively OR'd together. (Additional package
# resource dependencies are defined by repeating the entire
# "RESOURCE_NAME" block.)
#
# Example : RESOURCE_NAME /net/interfaces/lan/status/lan0
# RESOURCE_POLLING_INTERVAL 120
# RESOURCE_START automatic
# RESOURCE_UP_VALUE = running
# RESOURCE_UP_VALUE = online
#
# Means that the value of resource /net/interfaces/lan/status/lan0
# will be checked every 120 seconds, and is considered to
# be 'up' when its value is "running" or "online".
#
# Uncomment the following lines to specify package resource dependencies.
#
# Legal values for RESOURCE_NAME: <Any String>
# Legal values for RESOURCE_POLLING_INTERVAL: ( (value > 0) && (value <= 86400) ).

# "STORAGE_GROUP" specifies CVM specific disk group used in this package.
#
# WARNING: "STORAGE_GROUP" is intended to support CVM 3.5 only. This
# parameter has been depreciated. It will be obsoleted in a future
# Serviceguard release! For CVM 4.1 or later disk groups, Please replace
# it by configuring package dependency on SG-CFS-pkg inside this package.
#
# Enter the names of the storage groups configured for this package.
# Repeat this line as necessary for additional storage groups.
#
# Storage groups are only used with CVM disk groups. Neither
# VxVM disk groups or LVM volume groups should be listed here.
# By specifying a CVM disk group with the "STORAGE_GROUP" keyword
# this package will not run until the CVM system multi node package is
# running and thus the CVM shared disk groups are ready for activation.
#
# Example : STORAGE_GROUP "dg01"
# STORAGE_GROUP "dg02"
# STORAGE_GROUP "dg03"
# STORAGE_GROUP "dg04"
#
# Legal values for STORAGE_GROUP:
# Any string that starts and ends with an alphanumeric character, and
# contains only alphanumeric characters, dot(.), dash(-), or underscore(_) in the middle.
# Maximum string length is 39 characters.

# Access Control Policy Parameters.
#
# "USER_NAME", "USER_HOST" and "USER_ROLE" specify who can administer
# this package.
#
# Three entries set the access control policy for the package: the
# first line must be "USER_NAME", the second "USER_HOST", and the third "USER_ROLE".
# Enter a value after each.
#
# 1. "USER_NAME" can either be "ANY_USER", or a maximum of
# 8 login names from the /etc/passwd file on user host.
# 2. "USER_HOST" is where the user can issue Serviceguard commands.
# Choose one of these three values: "ANY_SERVICEGUARD_NODE",
# or (any) "CLUSTER_MEMBER_NODE", or a specific node. For node,
# use the name portion of the official hostname supplied by the
# domain name server, not the IP addresses or fully qualified name.
# 3. "USER_ROLE" must be "PACKAGE_ADMIN". This role grants permission
# to "monitor", plus for administrative commands for the package.
#
# These policies do not affect root users. Access Policies defined in
# this file must not conflict with policies defined in the cluster
# configuration file.
#
# Example: to configure a role for user john from node noir to
# administer the package, enter:
# USER_NAME john
# USER_HOST noir
# USER_ROLE package_admin
#
# Legal values for USER_NAME:
# A string of tokens each of which starts with an alphanumeric character and contains
# only alphanumeric and underscore(_) characters. The tokens must be separated by a space
# or a tab character.
# Maximum length of each user_name is 39 character.
#
# Legal values for USER_HOST:
# Any string that starts and ends with an alphanumeric character, and
# contains only alphanumeric characters, dot(.), dash(-), or underscore(_)

# VOLUME GROUPS
# Specify which volume groups are used by this package. Uncomment VG[0]=""
# and fill in the name of your first volume group. You must begin with
# VG[0], and increment the list in sequence.
#
# For example, if this package uses your volume groups vg01 and vg02, enter:
# VG[0]=vg01
# VG[1]=vg02
#
# The volume group activation method is defined above. The filesystems
# associated with these volume groups are specified below.
#
VG[0]="testvg"
# CVM DISK GROUPS
# Specify which cvm disk groups are used by this package. Uncomment
# CVM_DG[0]="" and fill in the name of your first disk group. You must
# begin with CVM_DG[0], and increment the list in sequence.
#
# For example, if this package uses your disk groups dg01 and dg02, enter:
# CVM_DG[0]=dg01
# CVM_DG[1]=dg02
#
# The cvm disk group activation method is defined above. The filesystems
# associated with these volume groups are specified below in the CVM_* variables.
#
#CVM_DG[0]=""
# NOTE: Do not use CVM and VxVM disk group parameters to reference
# devices used by CFS (cluster file system). CFS resources are
# controlled by the Disk Group and Mount Multi-node packages.
#
# VxVM DISK GROUPS
# Specify which VxVM disk groups are used by this package. Uncomment
# VXVM_DG[0]="" and fill in the name of your first disk group. You must
# begin with VXVM_DG[0], and increment the list in sequence.
#
# For example, if this package uses your disk groups dg01 and dg02, enter:
# VXVM_DG[0]=dg01
# VXVM_DG[1]=dg02
#
# The cvm disk group activation method is defined above.
#
#VXVM_DG[0]=""
#
# NOTE: A package could have LVM volume groups, CVM disk groups and VxVM disk groups.
#
# NOTE: When VxVM is initialized it will store the hostname of the
# local node in its volboot file in a variable called 'hostid'.
# The Serviceguard package control scripts use both the values of
# the hostname(1m) command and the VxVM hostid. As a result
# the VxVM hostid should always match the value of the hostname(1m) command.
#
# If you modify the local host name after VxVM has been
# initialized and such that hostname(1m) does not equal uname -n,
# you need to use the vxdctl(1m) command to set the VxVM hostid
# field to the value of hostname(1m). Failure to do so will
# result in the package failing to start.
# VXVM DISK GROUP IMPORT RETRY
# For packages using VXVM disk groups, if the import of a VXVM
# disk group fails then this parameter allows you to specify if you want
# to retry the import of disk group. Setting this parameter to "YES" will
# execute the command "vxdisk scandisks" to scan for potentially missing
# disks that might have caused the datagroup import to fail. This command
# can take a long time on a system which has a large IO subsystem.
# The use of this parameter is recommended in a Metrocluster with EMC SRDF environment.
# The legal values are "YES" and "NO". The default value is "NO"
VXVM_DG_RETRY="NO"
# VOLUME GROUP AND DISK GROUP DEACTIVATION RETRY COUNT
# Specify the number of deactivation retries for each disk group and volume
# group at package shutdown. The default is 2.
DEACTIVATION_RETRY_COUNT=2
# RAW DEVICES
# If you are using raw devices for your application, this parameter allows
# you to specify if you want to kill the processes that are accessing the
# raw devices at package halt time. If raw devices are still being accessed
# at package halt time, volume group or disk group deactivation can fail,
# causing the package halt to also fail. This problem usually happens when
# the application does not shut down properly.
# Note that if you are using Oracle's Cluster Ready Service, killing this
# service could cause the node to reboot.
# The legal values are "YES" and "NO". The default value is "NO".
# The value that is set for this parameter affects all raw devices associated
# with the LVM volume groups and CVM disk groups defined in the package.
KILL_PROCESSES_ACCESSING_RAW_DEVICES="NO"
# FILESYSTEMS
# Filesystems are defined as entries specifying the logical volume, the
# mount point, the mount, umount and fsck options and type of the file system.
# Each filesystem will be fsck'd prior to being mounted. The filesystems
# will be mounted in the order specified during package startup and will
# be unmounted in reverse order during package shutdown. Ensure that
# volume groups referenced by the logical volume definitions below are
# included in volume group definitions above.
#
# Specify the filesystems which are used by this package. Uncomment
# LV[0]=""; FS[0]=""; FS_MOUNT_OPT[0]=""; FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""
# FS_TYPE[0]="" and fill in the name of your first logical volume,
# filesystem, mount, umount and fsck options and filesystem type
# for the file system. You must begin with LV[0], FS[0],
# FS_MOUNT_OPT[0], FS_UMOUNT_OPT[0], FS_FSCK_OPT[0], FS_TYPE[0]
# and increment the list in sequence.
#
# Note: The FS_TYPE parameter lets you specify the type of filesystem to be
# mounted. Specifying a particular FS_TYPE will improve package failover time.
# The FSCK_OPT and FS_UMOUNT_OPT parameters can be used to include the
# -s option with the fsck and umount commands to improve performance for
# environments that use a large number of filesystems. (An example of a
# large environment is given below following the decription of the
# CONCURRENT_MOUNT_AND_UMOUNT_OPERATIONS parameter.)
#
# Example: If a package uses two JFS filesystems, pkg01a and pkg01b,
# which are mounted on LVM logical volumes lvol1 and lvol2 for read and
# write operation, you would enter the following:
# LV[0]=/dev/vg01/lvol1; FS[0]=/pkg01a; FS_MOUNT_OPT[0]="-o rw";
# FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""; FS_TYPE[0]="vxfs"
#
# LV[1]=/dev/vg01/lvol2; FS[1]=/pkg01b; FS_MOUNT_OPT[1]="-o rw"
# FS_UMOUNT_OPT[1]=""; FS_FSCK_OPT[1]=""; FS_TYPE[1]="vxfs"
#
#Nested mount points may also be configured
#
#LV[0]=""; FS[0]=""; FS_MOUNT_OPT[0]=""; FS_UMOUNT_OPT[0]=""; FS_FSCK_OPT[0]=""
#FS_TYPE[0]=""
#
# VOLUME RECOVERY
#
# When mirrored VxVM volumes are started during the package control
# bring up, if recovery is required the default behavior is for
# the package control script to wait until recovery has been completed.
#
# To allow mirror resynchronization to ocurr in parallel with
# the package startup, uncomment the line
# VXVOL="vxvol -g \$DiskGroup -o bg startall" and comment out the default.
#
# VXVOL="vxvol -g \$DiskGroup -o bg startall"
VXVOL="vxvol -g \$DiskGroup startall" # Default
# FILESYSTEM UNMOUNT COUNT
# Specify the number of unmount attempts for each filesystem during package
# shutdown. The default is set to 1.
FS_UMOUNT_COUNT=1
# FILESYSTEM MOUNT RETRY COUNT.
# Specify the number of mount retrys for each filesystem.
# The default is 0. During startup, if a mount point is busy
# and FS_MOUNT_RETRY_COUNT is 0, package startup will fail and
# the script will exit with 1. If a mount point is busy and
# FS_MOUNT_RETRY_COUNT is greater than 0, the script will attempt
# to kill the user responsible for the busy mount point
# and then mount the file system. It will attempt to kill user and
# retry mount, for the number of times specified in FS_MOUNT_RETRY_COUNT.
# If the mount still fails after this number of attempts, the script
# will exit with 1.
# NOTE: If the FS_MOUNT_RETRY_COUNT > 0, the script will execute
# "fuser -ku" to freeup busy mount point.
FS_MOUNT_RETRY_COUNT=0
#
# Configuring the concurrent operations below can be used to improve the
# performance for starting up or halting a package. The maximum value for
# each concurrent operation parameter is 1024. Set these values carefully.
# The performance could actually decrease if the values are set too high
# for the system resources available on your cluster nodes. Some examples
# of system resources that can affect the optimum number of concurrent
# operations are: number of CPUs, amount of available memory, the kernel
# configuration for nfile and nproc. In some cases, if you set the number
# of concurrent operations too high, the package may not be able to start
# or to halt. For example, if you set CONCURRENT_VGCHANGE_OPERATIONS=5
# and the node where the package is started has only one processor, then
# running concurrent volume group activations will not be beneficial.
# It is suggested that the number of concurrent operations be tuned
# carefully, increasing the values a little at a time and observing the
# effect on the performance, and the values should never be set to a value
# where the performance levels off or declines. Additionally, the values
# used should take into account the node with the least resources in the
# cluster, and how many other packages may be running on the node.
# For instance, if you tune the concurrent operations for a package so
# that it provides optimum performance for the package on a node while
# no other packages are running on that node, the package performance
# may be significantly reduced, or may even fail when other packages are already running on that node.
#
# CONCURRENT VGCHANGE OPERATIONS
# Specify the number of concurrent volume group activations or
# deactivations to allow during package startup or shutdown.
# Setting this value to an appropriate number may improve the performance
# while activating or deactivating a large number of volume groups in the
# package. If the specified value is less than 1, the script defaults it
# to 1 and proceeds with a warning message in the package control script logfile.
CONCURRENT_VGCHANGE_OPERATIONS=1
#
# USE MULTI-THREADED VGCHANGE
# Specify whether multi-threaded vgchange is to be used if available.
# 0 means that the multi-threaded option is not to be used and 1 means
# that the multi-threaded option is to be used. The default is set to 0.
# Multi-threaded vgchange has potential performance benefits.
# If the activation order of the paths defined in lvmtab is important then
# multi-threaded vgchange should not be used. If mirrored volume groups
# are synced during activation then using multi-threaded vgchange may worsen performance.
# Using the multi-threaded vgchange option can improve the activation
# performance of volume groups with multiple disks.
# CONCURRENT_VGCHANGE_OPERATIONS option is beneficial when mutiple
# volume groups need to be activated. To get the best performance for
# volume group activation, use the multi-threaded vgchange option in
# combination with the CONCURRENT_VGCHANGE_OPERATIONS option.
ENABLE_THREADED_VGCHANGE=0
# CONCURRENT FSCK OPERATIONS
# Specify the number of concurrent fsck to allow during package startup.
# Setting this value to an appropriate number may improve the performance
# while checking a large number of file systems in the package. If the
# specified value is less than 1, the script defaults it to 1 and proceeds
# with a warning message in the package control script logfile.
CONCURRENT_FSCK_OPERATIONS=1
# CONCURRENT MOUNT AND UMOUNT OPERATIONS
# Specify the number of concurrent mounts and umounts to allow during
# package startup or shutdown.
# Setting this value to an appropriate number may improve the performance
# while mounting or un-mounting a large number of file systems in the package.
# If the specified value is less than 1, the script defaults it to 1 and
# proceeds with a warning message in the package control script logfile.
CONCURRENT_MOUNT_AND_UMOUNT_OPERATIONS=1
# Example: If a package uses 50 JFS filesystems, pkg01aa through pkg01bx,
# which are mounted on the 50 logical volumes lvol1..lvol50 for read and write
# operation, you may enter the following:

# IP ADDRESSES
# Specify the IP and Subnet address pairs which are used by this package.
# You could specify IPv4 or IPv6 IP and subnet address pairs.

# For example, if this package uses an IP of 192.10.25.12 and a subnet of
# 192.10.25.0 enter:
# IP[0]=192.10.25.12
# SUBNET[0]=192.10.25.0
# (netmask=255.255.255.0)
#
# Hint: Run "netstat -i" to see the available subnets in the Network field.
#
# For example, if this package uses an IPv6 IP of 2001::1/64
# The address prefix identifies the subnet as 2001::/64 which is an available
# subnet.
# enter:
# IP[0]=2001::1
# SUBNET[0]=2001::/64
# (netmask=ffff:ffff:ffff:ffff::)
# Alternatively the IPv6 IP/Subnet pair can be specified without the prefix
# for the IPv6 subnet.
# IP[0]=2001::1
# SUBNET[0]=2001::
# (netmask=ffff:ffff:ffff:ffff::)
#
# Hint: Run "netstat -i" to see the available IPv6 subnets by looking
# at the address prefixes
# IP/Subnet address pairs for each IP address you want to add to a subnet
# interface card. Must be set in pairs, even for IP addresses on the same
# subnet.

# SERVICE NAMES AND COMMANDS.
# Specify the service name, command, and restart parameters which are
# used by this package. Uncomment SERVICE_NAME[0]="", SERVICE_CMD[0]="",
# SERVICE_RESTART[0]="" and fill in the name of the first service, command,
# and restart parameters. You must begin with SERVICE_NAME[0], SERVICE_CMD[0],
# and SERVICE_RESTART[0] and increment the list in sequence.
#
# For example:
# SERVICE_NAME[0]=pkg1a
# SERVICE_CMD[0]="/usr/bin/X11/xclock -display 192.10.25.54:0"
# SERVICE_RESTART[0]="" # Will not restart the service.

# SERVICE_NAME[1]=pkg1b
# SERVICE_CMD[1]="/usr/bin/X11/xload -display 192.10.25.54:0"
# SERVICE_RESTART[1]="-r 2" # Will restart the service twice.
#
# SERVICE_NAME[2]=pkg1c
# SERVICE_CMD[2]="/usr/sbin/ping"
# SERVICE_RESTART[2]="-R" # Will restart the service an infinite
# number of times.
#
# Note: No environmental variables will be passed to the command, this
# includes the PATH variable. Absolute path names are required for the
# service command definition. Default shell is /usr/bin/sh.
#
#SERVICE_NAME[0]=""
#SERVICE_CMD[0]=""
#SERVICE_RESTART[0]=""
# DEFERRED_RESOURCE NAME
# Specify the full path name of the 'DEFERRED' resources configured for
# this package. Uncomment DEFERRED_RESOURCE_NAME[0]="" and fill in the
# full path name of the resource.
#
#DEFERRED_RESOURCE_NAME[0]=""
# DTC manager information for each DTC.
# Example: DTC[0]=dtc_20
#DTC_NAME[0]=
# HA_NFS_SCRIPT_EXTENSION
# If the package uses HA NFS, this variable can be used to alter the
# name of the HA NFS script. If not set, the name of this script is
# assumed to be "hanfs.sh". If set, the "sh" portion of the default
# script name is replaced by the value of this variable. So if
# HA_NFS_SCRIPT_EXTENSION is set to "package1.sh", for example, the name
# of the HA NFS script becomes "hanfs.package1.sh". In any case,
# the HA NFS script must be placed in the same directory as the package
# control script. This allows multiple packages to be run out of the
# same directory, as needed by SGeSAP.

注意:假设因进程失败引起应用包orapkg在随意节点切换失败,此时节点会设置状态不同意orapkg在随意节点上执行。此时我们要用cmmodpkg命令实现包的自己主动切换。例如以下
hbyxdb1:root /oracle/app/oracle/product/11.2.0/db_1/bin>cmrunpkg orapkg启动pkg
Unable to run package orapkg on node hbyxdb1, the node switching is disabled
Unable to run package orapkg on node hbyxdb2, the node switching is disabled
hbyxdb1:root /oracle/app/oracle/product/11.2.0/db_1/bin>cmmodpkg -e -n hbyxdb1 orapkg#(enable package switching 使当前down掉的pkg在一个执行的节点上启动)
cmmodpkg: Completed successfully on all packages specified
hbyxdb1:root /oracle/app/oracle/product/11.2.0/db_1/bin>cmmodpkg -e -n hbyxdb2 orapkg
cmmodpkg: Completed successfully on all packages specified
6.2 停止集群的步骤:
6.2.1 首先停止应用包orapkg(事实上就是共享磁盘testvg) ,不论什么一台机器都能够::
hbyxdb1:root /etc/cmcluster>cmhaltpkg orapkg
Halting package orapkg on node hbyxdb1
Successfully halted package orapkg on node hbyxdb2
One or more packages or package instances have been halted.
cmhaltpkg: Completed successfully on all packages specified
6.2.2 然后停止cluster ,不论什么一台机器都能够:
hbyxdb1:root /etc/cmcluster>cmhaltcl -v
Node hbyxdb1 is already halted.
Disabling all packages from starting on nodes to be halted.
Disabling all packages from running on hbyxdb2.
Warning: Do not modify or enable packages until the halt operation is completed.
Waiting for nodes to halt ..... done
Successfully halted all nodes specified.
Halt operation complete.
hbyxdb2:root /etc/cmcluster>
基本的错误信息在:
/var/adm/syslog/syslog.log
具体的错误信息在/etc/cmcluster下,如:/etc/cmcluster/clusterpkg/cluster.cntl.log 。
附经常使用命令:
