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.
                
                Regards
                Mike K
