next in thread | raw e-mail | index | archive | help
Hi all,
I would appreciate any thoughts on the following:
PII/233, 128MB RAM clone running FreeBSD 2.2.6
Adaptec 2940UW, SCSI ID 7
sd0, sd1, sd2 are IBM DCAS-34330W S65A wide drives (SCSI ID 0,3,and 5 respectively)
sd1 and sd2 make up a ccd mirror set mounted at /usr/home
other devices: Seagate tape drive at SCSI ID 2 and Toshiba CD-ROM at SCSI ID 6
dmesg shows all kinds of SCSI-related errors (excerpts included) and I would entertain any opinions on whether I should suspect the host adapter, the drives, or both. Incidentally, I have another identical box where everything's the same except the mount point for the ccd pair, and it works fine.
My vendor will happily replace whatever hardware I send back, but I'd like to know I'm addressing the right issue. Thanks in advance for the help.

Sometimes this command executes instantly, other times it takes up to ten seconds to return, and when it does I get lots of the above unpleasant log entries.
Here's dmesg after a boot (it will boot cleanly):
