Start watching your message queue numbers on your Master,
might be time to bump them up a bit. We saw this frequently on our largest
Windows Masters and ended up having to increase the heap sizes quite a bit on
them.

Thanks
TIm,
I understand what
you mean and thats what i used to think, but bptm has already selected the media
and is stating it is writing. I've checked ACS logs and can see the associated
mount and no subsequent job grabs the same tape. So in effect it's saying it
can't lock the media itself, not sure whether the old SCSI reserve comes in to
play and something has been left around from a previous mount. I'm prepared to
be completely blown out of the water.

Michael,
The "unable to lock media"
message has to do with bptm selecting media. Without the log, my guess
is that you'll see bptm is attempting to obtain a piece of media for a
backup. One part of that process is going through it's local mediaDB to
see if it fan find a match for what it needs (correct volume pool, retention,
etc). If a particular tape is in use, then you'll see the "unable to
lock media" message.
I don't think this is related to the problem you
originally posted. BTW, what patch level?

Folks,
Not
sure whether anyone can help or give a workaround solution?
We're
having issues in NBU 5.1 environment with HP-UX media servers and
jobs not going to end writing. This is a fairly irregular occurrence but
always tends to occur with logical logs in the middle of the night (oh
joy!). This isn't a scheduler issue as everything else chugs along
nicely. We're using ACSLS 7.1.0.
>From bptm logs I can see lots of
occurences of "12:08:30.310 [27067] <2> db_lock_media: unable to
lock media at offset 14' . Which could mean the media is in use by
another host, but I know it isn't. My guess is theres a communication
error between Media server and ACSLS.
So my question is, what can I
do to kickstart this? Sometimes I can go into the Activity Monitor and
end job, and it miraculously finishes. Other times when on-bar processes
go, then it's a Master server restart.
