NA just sent me a pair of PCI FC-AL's to replace the on-board FC-AL's. Apparently, the on-board FC-AL in filer A detected a loop break on its partners disks and that caused filer A to failover to filer B. It seems odd that filer A would be the one to failover upon detecting a loop break on its secondary FC-AL loop.
I've got a question about upgrading the FC-AL controllers though.
Two options for upgrading:
1) turn everything off, install the FC-AL contollers, move each filer's A-loop, turn everthing back on.
2) failover filer A, turn filer A off, upgrade its FC-AL controller, move its A loop, turn it back on, giveback to filer A from filer B. Then do the same on filer B.
This should be no different then adding a shelf to a cluster. Last time we did that, we used scenario (2). It didn't go smoothly, but that's because we were bitten by the 44+ days uptime bug.
