一、udev方式创建asm磁盘，采用uuid需要添加多块磁盘。大致流程如下
1、获取需要绑定为ASM Disk的磁盘uuid
2、新建/etc/udev/rules.d/99-oracle-asmdevices.rules,增加....
3、重启start_udev服务
二、/etc/udev/rules.d/99-oracle-asmdevices.rules创建
1、获取需要绑定为ASM Disk的磁盘uuid，比如我们要使用/dev/asm-diskaa作为ASM磁盘，那么uuid,下面实际文件中有：
[grid@shfpdb02 ~]$ /sbin/scsi_id -g -u -d /dev/asm-diskaa
369ce37410023334d07db5f9700000019
2、重启服务：
[root@rac1 ~]# start_udev
Starting udev:         [  OK  ]
[root@yxdb81 rules.d]# /usr/lib/udev/scsi_id -g -u -d /dev/asm-disk1 
1ATA_VBOX_HARDDISK_VBdc9899a6-862a29c7

磁盘的uuid是唯一的..不管名称有什么变化.
查看创建的磁盘组，查询可得
select name,state from v$asm_diskgroup;

set line 9999
select group_number,disk_number ,path from v$asm_disk;

创建asm方式很多主要有以下几种
1、Faking方式
2、裸设备方式
3、udev方式(它下面有两种方式)
  3.1 uuid方式.
  3.2 raw方式（裸设备方式）
4、asmlib方式（oracleasm）

创建asm磁盘，前提条件是需要准备以下

1、A disk or partition from a storage array //一个磁盘或者是磁盘阵列的分区
2、An entire disk or the partitions of a disk //是一个完整的磁盘或是一个磁盘的分区
3、Logical volumes              //一个磁盘的逻辑卷
4、Network-attached files (NAS) //NAS(Network-attached storage,网络连接存储)

KERNEL
事件设备的内部（内核）名称。

SUBSYSTEM
事件设备的子系统，如 SUBSYSTEM=usb（用于与 USB 设备有关的所有事件）。

PROGRAM
让 udev 执行外部程序。程序必须返回退出码零，才能成功。RESULT 键可使用程序的输出（打印到 stdout）。

RESULT
匹配上次 PROGRAM 调用的输出字符串。在与 PROGRAM 键相同的规则中包含该键，或在后面的一个中。
