Supported Power Path version on HPUX 11.31

we use V5.1 with HP-UX 11.23 which supports both DMX and clariion.

So i guess 11.31/V5.1 could do the same!

thanks for your reply . I checked with EMC support and they are working on power path of hpux 11.iv3 . this is what the EMC reply was

HP-UX 11v3 doesn't' support active/pasive functionality as 11v2 does. Engineering is currently working on it and the next version of Powerpath for HP-UX will work with 11v3, but at the moment the only option is PVLinks and the native failover

Correct, a CLARiiON is an active/passive array so is not currently suported for PowerPath 5.1 on 11iv3.
The DMX on the other hand is an active/active array and is supported for PowerPath 5.1 on 11iv3.
