for disk in `ls /dev/sd*`
do
echo $disk
/usr/lib/udev/scsi_id –whitelisted –replace-whitespace –device=$disk
done

– 产生设备的 UUID
[root@db12c_01 ~]# for disk in `ls /dev/sd*`
do
echo $disk
/usr/lib/udev/scsi_id –whitelisted –replace-whitespace –device=$disk
done

让配置生效：
/sbin/udevadm trigger –type=devices –action=change
udevadm control –reload-rules

查看生效后的设备名：
[root@db12c_01 ~]# ls -l /dev/as*
lrwxrwxrwx 1 root root 4 Nov 21 00:38 /dev/asm-diskb – sdb1
lrwxrwxrwx 1 root root 4 Nov 21 00:38 /dev/asm-diskc – sdc1
lrwxrwxrwx 1 root root 4 Nov 21 00:38 /dev/asm-diskd – sdd1
lrwxrwxrwx 1 root root 4 Nov 21 00:38 /dev/asm-diske – sde1
lrwxrwxrwx 1 root root 4 Nov 21 00:38 /dev/asm-diskf – sdf1

在做配置的时候，发现第二个节点配置时需要读取一下磁盘的分区信息才能成功绑定

[root@db12c_02 ~]# fdisk /dev/sdf
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Command (m for help): p

Disk /dev/sdf: 4294 MB, 4294967296 bytes, 8388608 sectors
Units = sectors of 1 * 512 = 512 bytes
