Could be a bad drive, bad tape, bad cable...

Try a new tape and cleaning the drive with a tape cleaning cartridge.

I assume you have rebooted and tried again (just to make sure it wasn't a hangup)?

Power down the server, and open up the case, look for loose data cables, or loose
SCSI card. (it happens)...


If everything checks out fine, find another tape drive to test with...

Hi,

I have a Dell PowerEdge server with a RAID 5 and a SCSI tape drive. For the
past two years, the tape drive has worked fine. All of the sudden I get:

  DUMP: Date of this level 0 dump: Mon Jun 16 01:00:00 2003
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/aacd0s1a (/) to /dev/sa0
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 297479 tape blocks.
  DUMP: Cannot open output "/dev/sa0".
  DUMP: fopen on /dev/tty fails: Device not configured
  DUMP: The ENTIRE dump is aborted.

When doing a dump. mt status shows:

server1# mt -f /dev/sa0 status
mt: /dev/sa0: Input/output error

Does this sound like a scsi bus problem, or perhaps a bad drive? Anything I
can do to tell for sure what the problem is? Thanks,

Joe

I worry about my child and the Internet all the time, even though she's
too young to have logged on yet. Here's what I worry about. I worry
that 10 or 15 years from now, she will come to me and say "Daddy, where
were you when they took freedom of the press away from the Internet?"

System Administration - It's a dirty job, but somebody said I had to do it.
