Hi all,
I have an AIX client (5.1.6.9, TSM server at 5.2.2.1), which needs to
backup it's files as fast as possible, therefore I modified it's dsm.sys
to give it "Resouceutilization 10". On TSM server this node has "max
mount points  2", and belongs a domain where primary pool (called
diskpool_aix) is on disk. This diskpool has a next storage pool called
"tapelto1_aix" which is collocated, and has no max size threshold.
Since I increased this resourceutilization parameter, it looks like the
client regularly sends it's backups directly to tapelto1_aix, even
initiating two parallel tape mounts, without going thru diskpool ...

Activity log looks like this (node name hidden for security reasons):
Date/Time Message --------------------

Tcp/Ip XXXXX (50490)). (SESSION: 419 574)

Tcp/Ip XXXXX (50491)). (SESSION: 419 575) 
04/05/04 02:21:06 ANR8337I LTO volume 000217 mounted in drive LTO1DR4

419575 opened output volume 000217. (SES SION: 419575)
Off course this is not really what I intended to get : I now have a node
monopolizing several tapes with very low occupation, that can't even be
reclaimed ...
Nothing special noticeable at the same time, except that a migration
happenend for this disk pool approximatively 20 minutes later, so it was
quiet full. Could that be a reson for such a behaviour ? Any other
explanations, ideas ?!
Thanks in advance !
