I don't know where else to ask this, hoping you'll forgive me! I am
using bareos, but this seems to be something else.
I have an HP-branded HH SAS LTO5 tape drive that has been working fine
until just recently, when it has started rejecting tapes. The symptom is
that reading from the tape basically works, but attempts to write any
noticeable amount of data (more than a second or so of writing at speed)
cause it to abruptly stop mid flight, and then what I can only presume
is some sort of reset before it rewinds and errors the write out with an
I/O error. I can write a bareos label to the tape, but starting a job
fails after about 700 tape blocks.
I've tested the drive with the hp_ltt console tools (linux) and it is
reported as being fine. (excellent margin). Testing with hp_ltt a tape
on which it's already errored fails again in the same way, and at least
once the test failed to complete. Switching to a once-written tape
experienced the same issues although that drive had written to that tape
before without issue. I don't currently have any *new* LTO5 media to try
with though the tape this all started on was new at that time.
Any ideas what's wrong?
One thing I'm concerned about is that possibly the drive is somehow
damaging otherwise good tapes... is that possible?
Thanks in advance,
Ruth
