RHEL8 使用UDEV配置ASM磁盘

1.虚拟机需要在vmx文件中添加，才能显示UUID
disk.enableUUID = "TRUE"

2. （可省略）

rm -rf  99-oracle-asmdevices.rules

3.创建文件

for i in a b c d e f g;
do
echo "KERNEL=="sd?",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`",SYMLINK+="asm-disk$i",OWNER="grid",GROUP="asmadmin",MODE="0660"" >>/etc/udev/rules.d/99-oracle-asmdevices.rules;
done

 注意未分区用 $name
分区用       $parent

4.加载

udevadm trigger --type=devices --action=change

5.验证

[root@mtxdb ~]# ls -ltr /dev/asm*
