Help with LUNS

[Sijis Aviles]

Eric,

I'm using PP 4.5.1, so it might vary a little, but look into the
following command: emcpreg

In my case its:

emcpadm renamepseudo -s emcpower<old> -t emcpower<new>

You'll want to make sure the LUNs match (powermt display dev=all) and
grep the "Logic device ID" line when you make the changes.

Hopefully that helps,

Sijis
