1、查看磁盘分区UUID：
[root@rac01 ~]# blkid

/dev/sda1: UUID="21b2b922-fcb7-461f-bdc6-3bd92259f8d7" TYPE="xfs"
/dev/sda2: UUID="WC12Xe-0neg-Kmhp-u691-8bxn-8PpF-PuGgHH" TYPE="LVM2_member"
/dev/mapper/rhel-root: UUID="774aa4fa-2bbe-4636-a3ce-3a8aec9cdb40" TYPE="xfs"
/dev/mapper/rhel-swap: UUID="01075670-9314-4899-8d0f-23af11882416" TYPE="swap"
/dev/sr0: UUID="2016-10-19-18-32-06-00" LABEL="RHEL-7.3 Server.x86_64" TYPE="iso9660" PTTYPE="dos"
[root@rac01 ~]#
[root@rac01 ~]# ls -l /dev/disk/by-uuid/

[root@rac01 ~]#
使用/lib/udev/scsi_id查看磁盘UUID
[root@rac01 ~]# /lib/udev/scsi_id --help
Usage: scsi_id [OPTION...] DEVICE
SCSI device identification.
-h --help Print this message
--version Print version of the program
-d --device= Device node for SG_IO commands
-f --config= Location of config file
-p --page=0x80|0x83|pre-spc3- SCSI page (0x80, 0x83, pre-spc3-)
-s --sg-version=| Use SGv3 or SGv4
-b --blacklisted Treat device as blacklisted
-g --whitelisted Treat device as whitelisted
-u --replace-whitespace Replace all whitespace by underscores
-v --verbose Verbose logging
-x --export Print values as environment keys

3、使用脚本输入磁盘UUID
符号“c d e f g h”为磁盘名
linux 7.x脚本为

编写/etc/udev/rules文件,添加ASM块设备
将生成的内容保存在99-oracle-asmdevices.rules文件中。
修改磁盘名,便于识别：asm-grid1……
vim /etc/udev/rules.d/-oracle-asmdevices.rules linux .x #linux .x
