EVA, VMS Blade and preferred paths

I've gotten the answer I needed from the storage vendor...

Who is your storage vendor?

This was NetApp. I asked them if I should enable ALUA on the VMS luns and they responded that the host has to support ALUA.

NetApp's understanding of how VMS implements multipath is not quite accurate.

I've never used any NetApp stuff, and I have no direct knowledge of how well it "plays" with VMS; my experience is pretty much limited to using DEC/Compaq/HP storage subsystems with multipath, which is how we tested our code.

Pretty much anything that John Fisher says regarding storage can be taken as gospel.

For what it's worth, the multipath code hasn't been touched in a few years -- certainly not since V8.3.
