Oracle Linux 6 固定/dev/dm-* 的LUN disk權限設定方法

1.編輯

/etc/udev/rules.d/12-dm-permissions.rules

 

# Set permissions for first partition created on a multipath device (and detected by kpartx)

ENV{DM_NAME}=="asmdisk*", OWNER:="grid", GROUP:="asmadmin", MODE:="660", SYMLINK+="$env{DM_NAME}"

ENV{DM_NAME}=="votingdisk*", OWNER:="grid", GROUP:="asmadmin", MODE:="660", SYMLINK+="$env{DM_NAME}"

 

2.重啟multipathd

service multipathd restart

 

3.

最後用root執行 /sbin/start_udev

 

最後看到 /dev/asmdisk1 , asmdisk2 , votingdisk1 , votingdisk2 , votingdisk3 都會產生出來
