rhel7 udev

检查磁盘id:

[root@prod04 ~]# /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sdb

36000c291ff16db7914945dc7f9edd730

[root@prod04 ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sdb

36000c291ff16db7914945dc7f9edd730

生成udev文件：

[root@prod04 ~]# for i in {b..e};

do

echo KERNEL==\"sd?\", ENV{ID_SERIAL}==\"$(/usr/lib/udev/scsi_id -g -u -d /dev/sd$i)\", SYMLINK+=\"asm_disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\";

done

KERNEL=="sd?", ENV{ID_SERIAL}=="36000c291ff16db7914945dc7f9edd730", SYMLINK+="asm_diskb", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="sd?", ENV{ID_SERIAL}=="", SYMLINK+="asm_diskc", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="sd?", ENV{ID_SERIAL}=="", SYMLINK+="asm_diskd", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="sd?", ENV{ID_SERIAL}=="", SYMLINK+="asm_diske", OWNER="grid", GROUP="asmadmin", MODE="0660"

检查udev文件：

[root@prod04 ~]# cat /etc/udev/rules.d/99-oracle-asmdevices.rules

KERNEL=="sd?", ENV{ID_SERIAL}=="36000c291ff16db7914945dc7f9edd730", SYMLINK+="asm_diskb", OWNER="grid", GROUP="asmadmin", MODE="0660"

使udev生效：

udevadm control --reload-rules

udevadm trigger

检查磁盘权限：

[root@prod04 ~]#

[root@prod04 ~]# ll /dev/sd*

[root@prod04 ~]# ll /dev/asm_diskb
