Greetings, and Apologies for the second post-
Recap: I've replaced an external Python DDS2 (4mm tape, 4/8GB on 120m
tape) sitting on our 1000A's (narrow) SCSI bus, with a DDS3 (12/24GB on
125m tape). I'm having some trouble with it - it appears to back-up the
first partition of a multi-filesystem BRU backup, at about 907MB in
23minutes, but then something dies, the tape goes idle (and rewinds - this
is not behavior I saw with the DDS2. I didn't touch the backup script),
and the backup script essentially hangs, waiting for response from the
tape, which it seems to think is backing up the next filesystem.
This is under Tru64 4.0D.
I had a look at uerf, and I'm seeing a large number of CAM SCSI error
events. We have 4.3GB disk on target 0 and 18GB disk on target 2; the
tape is target 5. All of these are on bus 0. The errors involve class
DISK (TARGET x0 and x2) and TAPE (TARGET x5 - surprisingly, not very often
at all. Most errors are associated with the disks), and something new to
me: DEC SIM.
We're also experiencing long pauses in system response, not surprisingly.
Ideas? Perhaps the real problem is that our SCSI controller is failing?
Anything would be appreciated.
Cheers
Chris
