No Pseudo names seen for the paths using powerpath.

[Bedare Nikhil]

Hi,
I have installed emc powerpath on HP 11.23 and 11.31 machines.
powermt display dev=all shows me the details of the paths but the pseudo name is not seen.
Am I missing something.

===============================
bash-2.05# powermt display dev=all
CLARiiON ID=FCNHW063000188 [habhpth7]
Logical device ID=60060160DB081A002EAC4ECD8FF4DD11 [Virtual Disk 46]
state=alive; policy=CLAROpt; priority=0; queued-IOs=0
Owner: default=SP A, current=SP A

6 0/4/1/0.2.13.255.0.0.3 c6t0d3 SP A1 active alive 0 0

Thanks in advance,

I guess you're learned how PowerPath works on some other system architecture (Solaris, Linux?) and are trying to apply this knowledge to HP-UX.

PowerPath does not use pseudo names in HP-UX.

Instead, it hooks into the OS and re-directs disk I/O so that using any one disk device is the equivalent of using all the active paths of that particular disk together.
