I'll try to answer these best I can ...
1) The tape heads were cleaned to begin the process, and I have cleaned them
once since. So, best I can tell, the heads are clean.
2) Have not run diagnostics specifically on the Overland, but I have tried two
separate Overland Powerloader LTO jukeboxes, both with the same result. So,
since I've tried a couple of different units, that was my attempt to rule that
out as a possible reason.
3) I am receiving the errors on multiple tapes. In fact, I recently took out a
few tapes that were empty that I had been attempting to use and replaced them
with newly opened tapes, and the result has been the same.
This is one thing I have done that may be helping though ... last night, I
changed out the SCSI card for another one we had, a LSI Logic PCI-X Ultra320
SCSI host adapter. Windows picked up on it right away, it appears to be using a
generic Microsoft driver (which is different than the Adaptec, which was using
a newer driver from 2007 off their site).
When I attempted to re-run the tape label from the GUI, it did not take the
long period (30 minutes) to time out, it finished its efforts in about 2
minutes. The error I got then was a tape rewind error, saying that the tape
status was that the drive was ready.
Additionally, when I ran scanner -vv \\.\Tape2, it did not show the block
error. It then (properly I think?) showed the default block size zt 32kb, and
the maximum at 64kb.
Not sure at this point, might be making progress on it, hard to say. What
settings in Networker should I be looking for at this point, should I hard code
the HBA size to 64kb or leave it at handler default?
