Everything has been power cycled several times. The drives appear to go
down at the end of a job.

Subject: RE: [Veritas-bu] DLT drives going down
I assume its been physically powered down / restarted the drives /
robot?
Also, do the tapes go into a DOWN STATE during the middle of a backup,
or beginning or would you say very random?

They have upgraded the FW to the latest/greatest and checked
cables. I agree on the polling.

Hmmmmm what about Firmware for the SDLT tape drives?
Any loose cables / connections or possible to change Scsi
connectors?
=20
Not too sure why they feel the software is polling a drive could
cause a problem? - if anything I would say polling a device is probably
good as Netbackup confirms it can see it!
=20
The thing that makes me wonder if its cable / firmware issue is
the comment "MEDIUM NOT PRESENT".
Thanks

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.
