The problems were mostly related to SSO - problems discovering devices &
managing scsi reserves placed by other media servers on shared tape drives.

Those using one-drive-one-server architectures didn't seem to have
complaints.

I don't have answers to what you wrote but did want to caution you about
using RH for your master.  I've not been able to get RH EL AS 3 to
properly recognize my SAN environment.   From an earlier thread on this
list it appears I wasn't the only one.

Not sure if you're running SAN or direct SCSI but if the former thought
it best to mention it.

Greetings, list. 

Here's my situation. I have a HP-UX media/master server on 5.1 with a
newer Neo SDLT bot and an ancient DLT4000 Surestore bot. We're going to
be getting a shiny new Red Hat box soon to take over migrate backup
services.

I've just read the upgrade docs for 6.0, and I have to say that I'm a
little overwhelmed. If I read it right, an upgrade to 6 requires all the
clients to get the security software installed and upgraded to 6 as well
before they can get backed up, something I'm not sure I can accomplish
in a day.

In short, I'm considering leaving my HP-UX box at 5.1, and building the
new RH box on 6. My plan was to remove the Neo SDLT juke out of the 5.1
environment, plug it into my RH box,and import tapes there (as we've
used less than 30 SDLT's, it shouldn't be a huge deal). This would allow
me to do the icky client-side upgrades piecemeal, as I moved them to
6.0, they would then back up to the new box. Eventually, as all the
clients moved over, I could then move the old jukebox and stop
operations on the HP-UX box. 

The obvious problem is recovery; until I import every single tape, I
wouldn't know what tapes had backups from the 'old' system. 

I guess the thrust of the matter is:

1) Is the upgrade of an in-place 5.1 server to 6 easier than it reads
on paper?
1a) Do I really have to upgrade my clients to 6 before the server will
talk to them?
2) If I was running 6 on the 'old' system, could I follow the previous
advice, and move /usr/openv/netbackup/db and 
/usr/openv/volmgr/database, run the proper vmglob and bpmedia commands
on the new box and be done?

Thanks again for all your help!
