Also, make sure that in the management GUI for your Qlogic switch,
you have disabled "I/O Streamguard" for the ports connected to the
RAIDs, and enabled it for the ports connected to the hosts. Make
sure you are running a compatible firmware as well. IIRC 4.0.6.x was
compatible (older) and 5.x is compatible, but 4.2 wasn't (esp if you
used copper cables with the Apple card). No reason not to use 5.x if
you haven't updated yet.

I had this same problem as well with a QLogic switch. Swaping the
card with a new one resolved the problem instantly. I made some
posts on the Apple boards as well about this issue.
Hello,
We have 3 xserves running osx server 10.3.9 connecting through a
Qlogic sanbox fiber switch to Five (5) xraid controllers. We us
lun masking control which server sees which xraid. We have been
having a problem with two of the xserves now. AFP craches due to
the a Volume off one of the xraids is unmounting. We get the
below in syslog at the time it occurs:
Nov 5 00:17:56 dragon kernel: FusionMPT: Notification = 5
(External Bus Reset) for SCSI Domain = 0
Nov 5 00:17:56 dragon kernel: FusionMPT: External Bus Reset for
SCSI Domain = 0
Nov 5 00:17:56 dragon kernel: FusionMPT: Notification = 7 (Link
Status Change) for SCSI Domain = 0
Nov 5 00:17:56 dragon kernel: FusionFC: Link is down for SCSI
Domain = 0.
Nov 5 00:18:04 dragon kernel: FusionMPT:
FindTaskForControllerIdentifier() failed, targetID = 3, context = 0x
There is not link down notices on the xraid. So I was thinking
that it is either the switch, cable, card or xserve.
On one of the servers a couple weeks back when we were having the
problem I swapped cables with no effect. I then swapped fiber card
and it seemed to help. But now one of the other xserves is doing
it. Could I have two fiber cards go bad in a month?
