Hmmmmm what about Firmware for the SDLT tape drives?
Any loose cables / connections or possible to change Scsi connectors?
 
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!
 
The thing that makes me wonder if its cable / firmware issue is the comment
"MEDIUM NOT PRESENT".
Thanks

Subject: [Veritas-bu] DLT drives going down


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.
 
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).
 
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.
 
This was working from the end of June up until the second week in October.
 
Thoughts/suggestions?
