no powerpath and getting LUN ID

If you don't have powerpath and need to get the LUN ID to device special file (dsf)/ disk device on HP-UX, try using the following switch on the syminq command (part of Solutions Enabler):

syminq -identifier device_name

example:

syminq -identifier device_name | head

Device Device

------------------------- ----------------------- ----------------

Name Num Vendor Array ID Name

------------------------- ----------------------- ----------------

/dev/rdisk/disk428 09B8 EMC *redacted* N/A

/dev/rdisk/disk429 09B9 EMC *redacted* N/A

Actually I think the default syminq output (without any switches) shows the lun id, but it’s hidden in the “device” “serial Number” column. Skip the first 3 digits in the column (part of the array ID). The next 4 digits (or so) are the Lun ID.

Example (lun ID in bold):
