Bad storage port in AX150?

I have been having problems with setting up PowerPath to multipath between SP A1 and SP B1.  After wasting lots of time uninstalling and reinstalling powerpath,etc, etc, I found that if I move the same cable from SP B1 to SP B0, it detects it and multipath works.  If I move it back to SP B1, I cannot get it to work no matter what I try.

If I move SP A1 to SP A0 using it's cable, that works fine.  

1.  Does it sound like a bad GBIC on SP B1, or something else?
2.  Can these be replaced on the AX150?
3.  If so, what do I get?  This is a 2GB unit, so do I just get a 2GB GBIC?

Is this in a fabric configuration?  This sounds like a zoning or fabric pathing issue.

Sorry, I guess I forgot to mention that important point.  It is a direct connection - no switches involved.

Yes - it does sound suspiciously like a bad SFP (FWIW: GBICs were the big, old 1Gb modules).

I don't know if they're replaceable, but if they are, you'll be able to remove the SFP with the small wire bail. I don't believe there are any restrictions in the SFPs but try and keep the manufacturer consistent. IIRC EMC use Finnisar quite a bit.

If it doesn't have the wire bail does that always mean it is not replaceable?

Absence Of the wire bail suggests it's soldered  on to the board. If it is removable, you can do it live. Gently pull on it. If it comes out, you're in business. If it doesn't, use SPB port 0 instead.
