I have a 2 node cluster attached to Storagetek Flex280 SAN. Twice now the
SAN has had disks go bad (2 at once - not assigned to my cluster) and this
cluster (NW6.5sp5) has abended with a Fatal SAN error. The thought is the
drives failing put a lot of traffic on the bus and these 2 lost
communication for too long with the SBD?? My NW6.0 cluster stayed up and
those servers are using Emulex HBA's.

Any ideas on what setting I need to check in the Qlogic configuration?
