Hi,
I have been fighting with msa1500/msa20/qlogic/freebsd5
issues for a while
now, and am trying to nail down where things are going bad.
I have
mentioned this before, my setup is an msa1500 controller
with 2 of the
msa(30?) SCSI shelves and two of the msa20 sata shelves. the
sata shelves
are ADG (i have also used raid5), one lun per shelf, 10
drives w/2 spares.
My msa1500s and msa20s all have the most recent firmware and
the qlogic
card(isp0: <Qlogic ISP 2312 PCI FC-AL Adapter>) with
the ispfw module
dynamically loaded.
the issues are usually that drives and luns will just take
themselves
offline, mark disks bad, and pannic my freebsd box. the luns
are
invariably fine when brought back up, and after fsck can be
used for
random amount of time before this happens again. syslog
shows occasional
timeouts and resets.
what i want is a tool or tools to help me test the setup
from the freebsd
box through to the san and help me pinpoint the problem
area. does such a
thing exist?
thanks,
Brad
