Re: EMC Powerpath
the command for powerpath are the same.
powermt display dev=all
if you have mixed san enviroment clariion/symmetrix you could define a class
powermt display dev=all class=symm

Re: EMC Powerpath
If you are using hp-ux 11.31 then it has its own multipathing solution.
If you have 11.23 or below version check any Powerpath software is installed:
# swlist EMCpower
to see devices
# powermt display dev=all
To see options
# powermt display options

Re: EMC Powerpath
To see if you have multiple paths to your EMC storage, first identify the DSFs of your EMC LUNs using:
ioscan -funNC disk
Then for each EMC disk take a look at the lunpaths the disk has to the array:
scsimgr lun_map -D /dev/rdisk/diskNN
You should see multiple active paths to the array.

Re: EMC Powerpath
if you are using hp-ux 11.31 you don't need to use powerpath.

Re: EMC Powerpath
The document blow says:
PowerPath does not manage multi-pathing on HP-UX 11i v3. Native multi-pathing is used for EMC devices.
