I have experienced a similar problem that was traced back to the way the
tape drives were setup. In my case, the engineer from the vendor daisy
chained my tape drives (shared the scsi bus) and Netbackup had a hard
time locating the correct drive etc. After we gave each drive their own
channel, remove the drives from Netbackup, and then setup each drive in
Netbackup everything started working again. I would start with Robtest
to see if I can mount a tape, rewind, & eject the tape from each drive.=20

Subject: [Veritas-bu] More strangeness
=20
Hi Gang -=20
=20
While I'm awaiting a call back from Veritas support, I'm wondering
if anyone knows what I can start looking at to troubleshoot this
problem. We are having more strangeness occurring in our environment,
but I'm not sure if this could be my system, or network or a combination
of the two. Our environment consists of an e250 Sun Master Server
running Solaris 7 and NBU 5.0 attached to a Quantum ATL Library, an e250
Sun Media Server running Solaris 8 attached to a Storagetek L700e w/7
drives. We are running remote-NDMP jobs to a NetApp Filer, and an EMC
Celerra system. For some reason, both of these jobs are failing with a
52 error - Media Manager timed out trying to mount a volume. And then
it eventually fails with a 219 error: the Required Storage Unit is
Unavailable.
=20
We have had this happen once before in December, and a power cycle
of the media server and tape library fixed the problem. What I
witnessed happening while this was going on is that when the job tries
to mount a tape in one of the NDMP assigned drives, drives 5 & 6 will go
into a DOWN-TLD state. When I bring those drives back up, drive 5 will
go down, but 6 will stay up. When I bring drive 6 up, they both go down
again. And this cycle repeats until the job is cancelled. I
power-cycled the library and media server yesterday, but the problem
persists.
=20
Has anyone seen this and know what might be happening? Should I get
my network people looking at this?
=20
Thanks so much!
