Thanks for response. Let me try to explain what the issue here. We have ASM disk group created with LUNS from different SAN frame. Now as per our standard the diskgroup should have LUNs from same SAN frame. I was thinking getting LUN id will give me some clue. Anyone has better solution than this? Regards,

Hi,
Troubleshooting a multi-node ASMLib installation [ID 811457.1] On existing or freshly labelled systems, you can identify and verify the LUNs, scsi IDs and ASM volume labelling on each cluster node with the following command:
|#*blkid|grep sd.*oracleasm|while read a b;do echo -n $a$b" scsi_id=";(echo $a|tr -d [:digit:]|tr -d [:]|cut -d"/" -f3|xargs -i scsi_id -g -s /block/{})done;*|
above is one long line .
Output :
|root_at_rmvsx1:~ # blkid|grep sd.*oracleasm|while read a b;do echo -n
$a$b" scsi_id=";(echo $a|tr -d [:digit:]|tr -d [:]|cut -d"/" -f3|xargs -i scsi_id -g -s /block/{})done;|
|/dev/sda1:LABEL="DATA0" TYPE="oracleasm"
scsi_id=14945540000000000646174612d3000000000000000000000||/dev/sdb1:LABEL="DATA0" TYPE="oracleasm"
scsi_id=14945540000000000646174612d3000000000000000000000
