system down - can't find luns

[Dana Holland]

One of my redhat boxes (AS 3.0) uses storage on an IBM FastT box.  The 
HBA is a qla2300.  The FastT flaked out on us Friday - it has since been 
rebooted and the other servers connected to it are working fine.

One server still doesn't see the filesystem located on the SAN.  When I 
reboot, it tells me that /dev/sdb1 can't be found.  The only way I can 
get the box up is to go into /etc/fstab and comment out the two file 
systems that live on the SAN.

When I do a modprobe -r qla2300 and then a modprobe -v qla2300, doing a 
cat of /proc/scsi/qla2300/1 and /proc/scsi/qla2300/2 looks fine - or at 
least I think it does, I'm still very new to the SAN world.  Here are 
the results of the cat command:

This box had never been rebooted since it was initially set up on the 
SAN (about 90 days) ago.  I'm wondering if there was some type of setup 
that I needed to do in the init files to make it recognize the SAN each 
time I reboot.  Like I said, we've had no prior experience with SANs, so 
this is a very new world to us.
