aix 6.1，grid 11.2.0.3+asm11.2.0.3+rac
建数据库的时候使用的是aix自带的多路径软件mpio，建了diskgroup
现在改造成veritas dmp多路径，已经修改了asm的disk_strings＝/dev/vx/rdmp/*，crs/asm启动的时候已经可以识别到磁盘/dev/vx/rdmp/开头的磁盘，但是读取不回原来的diskgroup信息。
crs启动的报错日志：

其需求为修改ASM DISK PATH的磁盘设备路径，但是由于11gR2 RAC+ASM的特殊性，导致CRS无法正常启动，虽然使用crsctl start crs -excl -nocrs的方式可以启动CSS服务和ASM实例，
但是最后还是报(clssnmCompleteInitVFDiscovery: Voting file not found)，这是由于Voteing file投票磁盘的位置没有合理更新导致的。
这里我们来学习一下，如何正确的修改11gR2 RAC+ASM下的ASM DISK路径：
1.我们来营造一个修改ASM DISK路径的环境，这里我们使用UDEV的设备名绑定服务，并利用UDEV将原本的ASM DISK从/dev/asm-disk* 修改为 /dev/rasm-disk*的形式， 这只需要修改udev rule文件即可实现：
[grid@maclean1 ~]$ export ORACLE_HOME=/g01/grid/app/11.2.0/grid [grid@maclean1 ~]$ /g01/grid/app/11.2.0/grid/bin/sqlplus / as sysasm SQL*Plus: Release 11.2.0.3.0 Production on Sun Jul 15 04:09:28 2012 Copyright (c) 1982, 2011, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Real Application Clusters and Automatic Storage Management options SQL> show parameter diskstri NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ asm_diskstring string /dev/asm*
可以看到当前ASM实例使用的asm_diskstring 为/dev/asm*， 切换到root用户修改UDEV RULE文件 ：
[root@maclean1 rules.d]# cp 99-oracle-asmdevices.rules 99-oracle-asmdevices.rules.bak [root@maclean1 rules.d]# vi 99-oracle-asmdevices.rules [root@maclean1 rules.d]# cat 99-oracle-asmdevices.rules KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB09cadb31-cfbea255_", NAME="rasm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB5f097069-59efb82f_", NAME="rasm-diskc", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB4e1a81c0-20478bc4_", NAME="rasm-diskd", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VBdcce9285-b13c5a27_", NAME="rasm-diske", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB82effe1a-dbca7dff_", NAME="rasm-diskf", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB950d279f-c581cb51_", NAME="rasm-diskg", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB14400d81-651672d7_", NAME="rasm-diskh", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VB31b1237b-78aa22bb_", NAME="rasm-diski", OWNER="grid", GROUP="asmadmin", MODE="0660"
以上修改了原始99-oracle-asmdevices.rules的UDEV RULE规则文件，生成的设备名被修改为/dev/rasm-disk*的形式，不同于之前的ASM DISK设备名， 这要求我们后续的一系列操作来保证RAC CRS可以正常启动。
当前运行时的votedisk和ocr 存放位置:

因为votedisk file的位置具体指向一个ASM DISK，所以后续我们会需要crsctl replace votedisk， 我们现在重启LINUX OS:

重启后自动获得了形如/dev/rasm-disk*的ASM DISK,查阅ASM日志可以发现css服务仍搜索/dev/asm*路径来获得ASM DISK，但是这将导致找不到任何有效的ASM DISK:

由于11gR2中CRS服务依赖于ASM，因为ocr存放在ASM中，所以ASM若无法有效启动，这导致CRS服务也无法正常工作:
[root@maclean1 ~]# crsctl check has CRS-4638: Oracle High Availability Services is online [root@maclean1 ~]# crsctl check crs CRS-4638: Oracle High Availability Services is online CRS-4535: Cannot communicate with Cluster Ready Services CRS-4530: Communications failure contacting Cluster Synchronization Services daemon CRS-4534: Cannot communicate with Event Manager
2. 以上是修改ASM DISK PATH磁盘路径的现状，我们需要通过以下操作来恢复CRS:
首先彻底关闭OHASD服务：
[root@maclean1 ~]# crsctl stop has -f CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'maclean1' CRS-2673: Attempting to stop 'ora.mdnsd' on 'maclean1' CRS-2673: Attempting to stop 'ora.crf' on 'maclean1' CRS-2677: Stop of 'ora.mdnsd' on 'maclean1' succeeded CRS-2677: Stop of 'ora.crf' on 'maclean1' succeeded CRS-2673: Attempting to stop 'ora.gipcd' on 'maclean1' CRS-2677: Stop of 'ora.gipcd' on 'maclean1' succeeded CRS-2673: Attempting to stop 'ora.gpnpd' on 'maclean1' CRS-2677: Stop of 'ora.gpnpd' on 'maclean1' succeeded CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'maclean1' has completed CRS-4133: Oracle High Availability Services has been stopped.
3. 以-excl -nocrs方式启动CRS，这将仅启动ASM 实例而不会启动CRS服务：
[root@maclean1 ~]# crsctl start crs -excl -nocrs CRS-4123: Oracle High Availability Services has been started. CRS-2672: Attempting to start 'ora.mdnsd' on 'maclean1' CRS-2676: Start of 'ora.mdnsd' on 'maclean1' succeeded CRS-2672: Attempting to start 'ora.gpnpd' on 'maclean1' CRS-2676: Start of 'ora.gpnpd' on 'maclean1' succeeded CRS-2672: Attempting to start 'ora.cssdmonitor' on 'maclean1' CRS-2672: Attempting to start 'ora.gipcd' on 'maclean1' CRS-2676: Start of 'ora.cssdmonitor' on 'maclean1' succeeded CRS-2676: Start of 'ora.gipcd' on 'maclean1' succeeded CRS-2672: Attempting to start 'ora.cssd' on 'maclean1' CRS-2672: Attempting to start 'ora.diskmon' on 'maclean1' CRS-2676: Start of 'ora.diskmon' on 'maclean1' succeeded CRS-2676: Start of 'ora.cssd' on 'maclean1' succeeded CRS-2679: Attempting to clean 'ora.cluster_interconnect.haip' on 'maclean1' CRS-2672: Attempting to start 'ora.ctssd' on 'maclean1' CRS-2681: Clean of 'ora.cluster_interconnect.haip' on 'maclean1' succeeded CRS-2672: Attempting to start 'ora.cluster_interconnect.haip' on 'maclean1' CRS-2676: Start of 'ora.ctssd' on 'maclean1' succeeded CRS-2676: Start of 'ora.cluster_interconnect.haip' on 'maclean1' succeeded CRS-2672: Attempting to start 'ora.asm' on 'maclean1' CRS-2676: Start of 'ora.asm' on 'maclean1' succeeded #建议同时修改CRS_HOME所在的ORACLE_BASE为777权限，避免可能的问题 [root@maclean1 ~]# chmod 777 /g01
4.修改ASM实例的disk_strings为当前的ASM DISK PATH信息:
[root@maclean1 ~]# su - grid
[grid@maclean1 ~]$ sqlplus / as sysasm

以上成功修改了asm_diskstring ，且更新了ASM DISKGROUP上的SPFILE ， 由于ASM使用共享的SPFILE所以其他节点上一般无需在做其他操作。
5. crsctl replace votedisk 命令将votedisk重置位置：
[root@maclean1 ~]# crsctl replace votedisk +systemdg
