381.0. "Pool problems" by ALFSS2::WHITTINGTON (Plug & Plague) Tue Feb 04 1997 08:26

    I was 'playing' around with pools on my jukebox, and I amd getting a
    media alert event: backup to pool 'Full' waiting for 2 writable backup
    tapes' message in my message gui. What would cause this?
    My pool definition for Full is = 
    Enabled -yes
    Pool type - Backup
    Archive only - no
    Label template - Full
    Groups - NT
    levels - full
    devices - \\.\Tape0
    store index entries - yes
    auto media verify - yes
    
    If I try to change any of these settings I get a message from
    Administrator - Cannot create or modify pools while server is busy.
    
    Any help would be appreciated

381.1everything is detective work, why make us guess this stuff?DECWET::LENOXAttack the future!Tue Feb 04 1997 08:4327
If something in a savegroup match the pool's specifications,
that is when one gets requests for tapes in the pool to be mounted.

What kind of saves are running (group NT should be running)?  What
is the schedule they are using (should be full for the day that 
the save started)?

It should be asking for 2 devices to be mounted if you have x
as the number of active devices and x-2 devices with tapes.
It should use \\.\Tape0, but either \\.\Tape0 is already in
use, or you don't have a tape with space in pool Full.

The server is busy... you can't modify something while the
server is using the definitions on what you're trying to modify.
Try modifying a jukebox resource during a save which uses the
resource, same thing happens.

So does this match with what is happening?  Only you can say,
but you haven't.  If I can guess this much, so can you.  If
something is wrong, you need to state what it is.  Sounds like
a perfectly normal state that one could get oneself into, 
although it would be nice if the server could catch that only
one tape could satisfy the request.  Pools are very tricky and
I don't expect that I will always get them right.  Knowing 
what else is happening on the system is critical to knowing if
there is a problem.
381.2Reboot cleared it upALFSS2::WHITTINGTONPlug & PlagueTue Feb 04 1997 09:437
    Well, I rebooted the server and the messages cleared up and I am back
    in business as far as backing up again. I looked like the group NT was
    not finished running for whatever reason.
    
    Thanks for the quick response.....
