PowerPath 5.5, Windows 2008 and HBA issues
Currently our environment uses QLogic HBAs (not my choice, I prefer Emulex). On our SQL cluster, they installed the QLogic cards and installed powerpath. Right now, PowerPath can only see one HBA, not both of them. For the life of my I do not know what the problem is.
I made sure the HBAs had the latest firmware/software/bios installed. I installed PowerPath 5.5 using EMC's recommendations and yes, MPIO does get installed. Why am I only seeing one HBA? Even if Solutions Enabler all I see is one HBA. When I used the QLogic CLI I can see both WWNs and the HBAs are checked into both the switch and the CX array.
Thoughts?!

Do you have any devices presented to the second (missing?) HBA?

Actually I found it, the HBA was disconnected from the storage group. I reconnected it and we’re good.
Thanks!

My guess is when they swapped HBAs the new HBA did not check into the storage group so I had to force a reconnect. Once I did that, problem solved.

It must have been something like that. When an HBA has no LUNs Powerpath doesn't see the LUN.
Please mark the question as answered by marking the correct answer.

In summation:

True, because in Unisphere you can "administratively disable" an HBA, which happens by default when you change a defective HBA for a new one. In solutions enabler you do the masking on the new HBA and it works. Indeed

Could be. If that was the case you should be able to see a 3rd HBA in the connectivity status (if they didn't remove the defective one)

They actually pulled the HBA and gave me the new WWN which I zoned in and connected to the host. I cleared the old WWN out of the host and thought it had registered with the storage group but that was not the case. I always thought PowerPath showed WWNs regardless and if there was no connection it would be X’d out. Guess that’s not true!

True, lol! Never have this issue with DMX/VMAX arrays though ☺
