Maybe - but no patch on the HP-UX box for this...

Is your Clariion on at least FLARE 26?

Earlier releases do not support 11.31.

Also make sure that your 11.31 LUNs have the failover mode set to 4 (ALUA) on the Clariion.

Basically I'd advise you to get hold of an up-to-date copy of the EMC HP-UX connectivity guide and have a good read on the 11.31 specific sections.
