BUG or hardware failure?
Over the last two weeks a very overworked Alpha running 2.2.16 has been
experiencing some SCSI issues. I can't tell if these crashes are hardware
or software related. If it is hardware related is it a drive going bad or
is it a controller card, cable, or some other issue? The machine runs
fine for a few days and then it occasionally displays odd messages about
inodes still having aliases (seen in table 1). Later after about 4 days
of uptime it gets stuck is a loop message (seen in table 2). It happens
about once a week now. After the machine is rebooted and fsck's it will
run fine for another week or so.
Some insight to this would be helpful, for if we have bad hardware I would
like to replace it, but if it's a kernel issue we would like to supply as
much information possible to fix it.
Review table 3 for hardware details. Thank you - Barrett
