centos7下如何使用udev配置asm磁盘

环境:

OS:Centos 7

1.生产规则文件

for i in b c d;
do
echo "KERNEL=="sd*",  ENV{DEVTYPE}=="disk",SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id -g -u -d $devnode",RESULT=="`/usr/lib/udev/scsi_id -g -u  /dev/sd$i`",RUN+="/bin/sh -c 'mknod /dev/asm-disk$i b  $major $minor; chown grid:asmadmin /dev/asm-disk$i; chmod 0660 /dev/asm-disk$i'"">>/etc/udev/rules.d/99-oracle-asmdevices.rules
done

2.启动udev

[root@localhost ~]# /sbin/udevadm trigger --type=devices --action=change

[root@localhost bin]# udevadm trigger

3.检查应用情况

[root@localhost ~]# ls -al /dev/asm*
