Confirmation of issue with SAN switch firmware

If you've been following along, we have been experiencing fibrechannel path problems here after upgrading Brocade switch firmware. After a huge roundabout investigation by HP and Brocade, it has finally been acknowledged that the version of the SAN switch firmware we upgraded to has a problem. Of course, I guessed that back in December.

We upgraded the 2GB switches to this version of firmware specifically to support an EVA 8000. As HP recommended we down-rev the switches to work around the problem, the EVA would be unsupported on the 2 GB switches. Fortunately, in the time it has taken to pinpoint the cause of the path issue, I added 4GB switches to the SAN.

So we had the alternative to move the EVA ports to the 4GB switches, which is what we did. Now after downgrading the firmware we are currently stable, with all paths available after one heck of a long "outage".
