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):
Device Product Device
-------------------------- --------------------------- ---------------------
Name Type Vendor ID Rev Ser Num Cap (KB)
-------------------------- --------------------------- ---------------------
/dev/rdisk/disk437 EMC SYMMETRIX 5874 93009C1000 35692800
