When I got in this morning, I noticed that a Novell client backup was
running and was waiting on a media mount for over 10 minutes.  I
queried the active processes and there was an active migration process.
 The tape that was being written to was the one that the bkup session
needed.  I raised the migration threshold of the disk stg pool that was
being migrated from (its high threshold is low: 55%) and cancelled the
migration process.  The bkup session immediately took off again.  I am
wondering though, the %util on the disk storage pool is hovering right
arount 100% while this bkup is occuring.  And its seems to come down a
few fractions of a percent while the %migrated seems to go up roughly
the same amount.  I have file caching on on the disk pool, but does
ADSM only free up disk space occupied by cached files on a as needed
basis???? I thought that anything that was cached would disappear once
ADSM saw it needed disk space.  Also I can't tell at what point the
migration will start up again since the %utilized is, like I said,
about 100%.   Do you subtract the %migr from the %util to get the
actual non-cached disk pool utilization????
Could someone tackle this one?????
