Roger,
We flush our disk pools daily by setting the hi & low parameters to 0
during the late afternoon and then reverting back to standard settings
prior to the start of the backup windows. This works fine. We also
backup the disk stgpool to the offsite tapes for a 2nd time just prior
to the flush to catch data that has been backed up during the day.
This just avoids an extra few tapes mounts later.
Cheers,
Simon

| We are using adsm v.3 with disk and tape storage pool. When our disk pool
| is nearly at high threshold and multiple backup schedules are starting, our
| disk pool likes to overflow because the migration processes can't move the
| data as fast as needed to tape. The backup and migration processes are
| interfering, backup becomes sloooow.
|
| I would like to empty my disk pools before backup starts. May I switch hi
| threshold to 0 to start migration and then switch back or should I use
| "move data"? Does anyone know? Any other ideas?
|
| Thanks in advance
