If I have defined the following (AIX server, ADSM 3.1): Primary Pool: Arcpool1 Copy Pool: Backuppool1 NextStgpool: Arcpool2 Copy Pool: Backuppool2
Arcpool1 is backed up to Backuppool1. Arcpool2 is the next storage pool, and is backed up to Backuppool2. If I migrate all the data in Arcpool1 to Arcpool2, do the files in Backuppool1 expire? Or do the files get backed up into the second pool, duplicating the data again? >>>>If you migrate the data in Arcpool1 to Arcpool2, the files in Backuppool1 do NOT expire. And if you then do a BACKUP STGPOOL from Arcpool2 to Backuppool2, then you are making a SECOND copy pool of your data. Think of it this way: The purpose of the copy pool is make a copy of ALL your primary data, whether it has migrated into your NextStgpool yet or not. What you should do, when you are ready to run your BACKUP STGPOOL, is run it twice: backup stgpool arcpool1 backuppool2 backup stgpool arcpool2 backuppool2 Backup stgpool is incremental; so when you run these commands TSM checks to see if there is any data in arcpool1 that is not ALREADY in backuppool2 and copies it; then does the same with arcpool2. So you don't have to worry about missing any data if you have an extra heavy load one day, and migration from arcpool1 to arcpool2 kicks in before you have a chance to do the backup stgpool to backuppool2. Running both commands makes sure ALL your data is covered in backuppool2. (On the other hand, if all the data is is ALREADY in arcpool2, nothing happens, so you don't get multiple copies of the same data in the same copy pool. TSM is smart that way!) And to get rid of your unneeded copy pool: FIRST run the two commands above to make SURE you have everything represented in backuppool2. Then for EACH VOLUME in backupool1, enter the command: DELETE VOLUME xxxxxx DISCARDDATA=YES. (You can do it from the command line or the admin interface, whatever.) That will purge the DB entries for all the data in THAT copy pool, and return all the tapes to 0% used. Then you can just delete the copy pool definition. Hope that helps. ************************************************************************ Wanda Prather The Johns Hopkins Applied Physics Lab 443-778-8769 [EMAIL PROTECTED] "Intelligence has much less practical application than you'd think" - Scott Adams/Dilbert ************************************************************************
