Hi,
If you are using multipath, then just do a:
multipath -ll <multipath name>
The lun id is the 4th number at the start of the path:
Lun_name_a (xxxxxxxxxxxxxxx) dm-22 xxxxxxx
size=1.0G features='0' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=4 status=active
|- 4:0:1:2 sdy 65:128 active ready running
`- 3:0:1:2 sdj 8:144 active ready running
In the above example the lun id is 2
And the xxxx between brackets on the first line will be your WWID.
If not using multipath, you can check in /sys/block/<sd name>/device.
There you can find the same info
[root@yyyyyy ~]# cd /sys/block/sdj/device/
[root@yyyyyy device]# ls -alhd scsi_disk*
lrwxrwxrwx 1 root root 0 Nov 20 16:28 scsi_disk:3:0:1:2 ->
../../../../../../../../class/scsi_disk/3:0:1:2

Subject: LUN ID
We have created asm disk using asmlib and assigned to the diskgroups. This was
done a while back. Is there a way now to get LUN ID of these disks? We are in
linux running 11.2.0.3 grid.
