If you are not at 2.1.0.8 GO TO IT NOW ! ! ! ! !
We've been running with only two 3590 tape drives in a 3494 atl and
were experiencing difficulties with mount request denied messages
where all (both) the tape drives were busy with reclamation (or two
migration processes) and would see where a tape would fill and while
the output tape was rewinding the request for a scratch would fail due
to no drives available...(sigh!) anyway, life is much better in
2.1.0.8... This is not your exact problem below but I would bet has
something to do with it.... BUT I've noticed that in 2.1.0.8 with two
tape drives active with two processes (say migration & recover or 2
migs, etc) that a Q MOUNT will return NO TAPES MOUNTED where if you
kill one process then a q mount will show a tape mounted... (sighx2)
I think I'm turning up a lot of odd problems because the two servers
we have here have up to 225GB/night tossed at them... within the last
two weeks things have grown beyond belief and I'm finding myself with
two ADSM servers running at 100% about 12 hours of the day and 80+%
the rest of the time... (sighx5) heck, I just got through producing
the numbers for 2 more tape drives / atl and now I'm thinking I need
two more servers and two extra tape drives along with another couple
hundred GB of dasd buffer pool... July we had @ 6TB of traffic on two
servers (3.5TB & 2.6TB) and I would bet that august numbers will show
7+terabytes of traffic.... (oh, my two servers are 59H & 591 w/ AIX
4.1 & about 120GB&180GB diskpools) 24hour periods show up to 225GB of
traffic with a majority (200GB) being backup/archive events
Summary: get on 2.1.0.8 it is MUCH better than 2.1.0.3 in heavy load
environments...
later
Dwight

Don't make ADSM fool on you:
q event * t=a gives the following output:
Scheduled Start Actual Start Schedule Name Status

So the BACKUP DATABASE and BACKUP STORAGEPOOL seems to completed successfully, B
,
looking in the actlog, you find the following:

Did I missed something and fool myself, or what?
(we are running ADSM V2.1.0.3 on a SP2 (AIX 4.1.4.0) using 3494 with 3590
units).
