Run:

fdisk -l | grep sd

Then run:

scsi_id -g -s /block/sd

Where is each of the devices names you get from fdisk.

You should get something like:

# scsi_id -g -s /block/sdb
1HITACHI 710110950068

Being the serial number and the CU:LDEV deivce at the end.

Thanks Ivan,

I do see the following:

360060e80042b050000002b05000013c4

Yes, 13c4 is the CU:LDEV. But what are the others and how to decode it.

cheers,

I'm not sure in your case about other values, it could be a mix of the serial number or can be derivated of the port WWN of the storage.
