Basically it uses DB and LOG volumes by filling up the first
then moving to the next one.  Of course as things progress,
some of the first volumes can be less than 100% full, this
is more so on DB Volumes.  The LOG is a sequentially
written device.

This is most easily observered when a new system is setup
(Or new volumes are added) and DB and LOG volumes are
on many disks and you can observe the disk I/O activity to prove it.

Disk Storage POOL volumes are more even.  TSM Server
attempts to spread data evenly (more or less) over all the
volumes for a DISK STGPOOL

Dear all,

I have looked through the adsm.org archives. The answers I got from
the
archives are not consistent.

I would vary much appreciate an answer to the question: Does TSM use
all DB
volumes for I/O (like round-robin) or does it fill a volume and then
goes
to the next one?

What about LOG volumes?

Many thanks in advance!!!!

Timo
