Hi Volker. How about your migration thresholds on the disk storage pool? Perhaps they are set very low so that anytime data lands in the disk storagepool it is almost instantly migrated. Check with a "q stpg xxxx f=d". Look for the High Mig Pct: Low Mig Pct: values. If these are set low (e.g. zeroes) migration will begin immediately any data is placed into the pool. At my site, these are usually set at H=90 & L=70, but once a day I set them both (via administrative command schedule) to zero to force the disk pool to empty. Cheers.

Our daily incremental backups go first do a disk storage pool on the TSM server. All 3 WinNT servers are associated to one schedule DAILY_INCREMENTAL with a 1 hour start up window. The backup processes spend most of the time looking for changed files. The overall amount of backed up data is 1-3 GB per night. During the backup process the TSM server mounts a tape in the ADIC every time one of the server systems start some activity. This happens in intervals of 2-4 minutes. These are by far too many tape mounts. The questions is WHY? The backup is supposed to go to disk, not to tape, so i expect to see NO or at least reduced tape activity. If this is a lack of knowledge on my part i will take your RTM recommendations. If not any help is appreciated. With kindest regards Volker --------------------------------------------------------------------------- - Volker Arendt mailto:[EMAIL PROTECTED] Gau
