求一个红帽7生成oracle udev.rule的脚本。谢谢各位
供 ASM 使用的磁盘为 sdd - sdi，d e f g h i 盘为 ASM 共享盘
可以使用lsblk命令查看磁盘信息：
# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 20G 0 disk
└─sda1 8:1 0 20G 0 part /
sdb 8:16 0 140G 0 disk
├─rootvg-backuplv 254:0 0 30G 0 lvm /backup
├─rootvg-homelv 254:1 0 10G 0 lvm /home
└─rootvg-oraclelv 254:2 0 100G 0 lvm /oracle
sdc 8:32 0 8G 0 disk [SWAP]
sdd 8:48 0 50G 0 disk
sde 8:64 0 50G 0 disk
sdf 8:80 0 200G 0 disk
sdg 8:96 0 50G 0 disk
sdh 8:112 0 50G 0 disk
sdi 8:128 0 50G 0 disk
使用以下命令配置ASM disk udev, 并将生成的配置文件拷贝到其它节点。
for i in d e f g h i; do
echo " KERNEL==\"sd*\", ACTION==\"add|change\", SUBSYSTEM==\"block\", PROGRAM==\"/lib/udev/scsi_id -g -u -d /dev/\$name\", RESULT==\"$(/lib/udev/scsi_id -g -u -d /dev/sd$i)\", SYMLINK+=\"asmdisks/asmdisk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""
done > /etc/udev/rules.d/99-oracle-asmdisks.rules
重载udev规则并触发udev生效：
# udevadm control --reload-rules
# udevadm trigger
# ls -l /dev/asmdisks/
如果使用了multipath软件，可以参考:
How to set udev rules in OL7 related to ASM on multipath disks (Doc ID 2101679.1)

参考这个来生成
