Two oddities I notice so far: 1). I created a devclass with vola-vole then started the copypool creations. I subsequently added volf. While it has created volumes in volf, only a few. It seems to use a roundrobin algorithm and since it had created a lot of volumes before the devclass def was updated to include volf, volf has gotten little use.
2).TSMMANAGER daily reports shows write errors to many of the volumes. I think this is generated when the 'volume' is full, because otherwise I can view the contents of the volume and the scheduled copyool creations completed succ4essfully over the weekend.

Yes, thank you. After posting my question I went to the 5.3 Admin Ref and saw I needed a file type device class for copypools. Defined then, changed the script, and since TSM saw them as a new copypool it copied all the data over, over this past weekend. about 2 TB of copypool data. We just have the large volumes ( that are RAID5) on a DS4800. TSM auto creates the volumes: /var/diskpool/satacopyv- CPSATABG CPSATABG 2,048.0 0.0 Empty oc/00008733.BFS /var/diskpool/satacopyv- CPSATABG CPSATABG 2,048.0 77.1 Filling oc/00008738.BFS /var/diskpool/satacopyv- CPSATABG CPSATABG 2,048.0 51.4 Filling oc/0000873E.BFS /var/diskpool/satacopyv- CPSATABG CPSATABG 2,048.0 98.6 Filling oc/00008743.BFS /var/diskpool/satacopyv- CPSATABG CPSATABG 2,048.0 98.6 Filling oc/00008747.BFS >From AIX mounted filesystem view: /dev/lvvgsata2 1042022400 0 100% 266 1% /var/diskpool/satacopy vola /dev/lvvgsata3 1042022400 0 100% 265 1% /var/diskpool/satacopy volb /dev/lvvgsata4 1042022400 0 100% 266 1% /var/diskpool/satacopy voc /dev/lvvgsata5 1042022400 0 100% 265 1% /var/diskpool/satacopy vold /dev/lvvgsata6 1042022400 0 100% 265 1% /var/diskpool/satacopy vole /dev/lvvgsata1 1042022400 1037871320 1% 17 1% /var/dispool/satacopy volf >>> [EMAIL PROTECTED] 12/04/06 12:24 PM >>> We tried file device class with our onsite pool with disappointing results. I believe the problem was our decision not to stripe across LUN's. This would have made performance much better, at the cost of a LUN failure causing more damage than if we used them indicidually. Now, I can't remember the last time I saw a LUN failure, but YMMV. We will probably address this issue again when the decision is made to move our copy pool to disk.
