We have an issue of drives randomly going down every night. NBU 5.0 mp5
HP-UX 11.11 STK L180 w/ STK 3400 scsi bridge.
=20
For some reason, 1 or more drives go down at random every night when
backups run. Different tapes and different drives. Backups will be
running fine and then drives begin to go down. These are SDLT320 drives.
once they go down, you can't use robtest to move the tapes (medium not
present error) or use the robtest unload command (device not present).
=20
If we power cycle the scsi bridge, we can talk to the drives and do what
ever we want. STK is claiming that there is something coming from the
host that is "polling" the library from the physical layer (assume HBA).
We have had the SA for the master/media server disable any polling and
load the latest patches from HP to no avail. We have changed from auto
index to a manual map index as well.
=20
This was working from the end of June up until the second week in
October.

Thoughts/suggestions?
