Is this using a seperate RAID card in each server, with the shared disk
subsystem being a JBOD (Just a Bunch Of Disks).

The only raid controllers I know of that support that configuration are
the IBM ServeRAID cards.  Is that what is in use?

If so, I have considered using those cards and would be interested in
what caused the failure.

FYI: Alan Robertson on the Linux-HA mailing lists works for IBM and
seems willing to chase down problems related to the ServeRAID cards. 
That may assume you are using the heartbeat clustering software.  

ie. Alan works for IBM, but I think working on Linux-HA (heartbeat) is
his full-time job.
