How to determine a disk location in an SE9900 Storage array.

Lets say you have more than one subsystem attached to your host or you just need to find CU number or ldev of an OS disk.

# format -e

select disk

format> scsi

scsi> inquiry

You will see an output such as..

Inquiry:

00 00 02 02 8b 00 01 3e 53 45 41 47 41 54 45 20 .......>HITACHI
53 54 33 39 31 37 33 57 20 53 55 4e 39 2e 30 47

The number we want is 01150401ec590170.

0115 The first 4 digits represent the Microcode version of the sub-system.

0401 Next 4 digits are not explained at this time.

ec59 This is the subsystem serial/mfg number in hex.

01 This is the CU number in the subsystem.

70 This is the LDEV ID within the above CU group.
