Hi Laura The 3584 is defined as a scsi library. Its all fairly straightforward.
There is no reason why several libraries cannot coexist. Just remember that tapes that were written in one library can't easily be moved to another library, even with the same drive type, when they have data on them. Here is one way to do a gradual migration. 1. Set up your new library and devclasses to use it. 2. set up a new set of copypools parallel to your old set of copypools, and run backup stg commands on all your primary pools until the copypools on the new library are up to date - this may take weeks, depending on how much data is to be copied, but can be stopped and restarted as necessary. Change housekeeping to copy new data to both new and old copypools. If you are using 5.3 parallel processing commands watch for the limit of 16 parallel commands at once. 3. Once the copypools are caught up, you can change your housekeeping to stop copying data to the old copypools. 4. create a new set of primary pools to parallel your old setup. Change your diskpools to migrate to the new primary pools. Change your managementclasses that go straight to tape to point to the new primary pools. Change your housekeeping to backup the new primary pools to the new copypools. 5. Make the nextstg of each of the old primary pools to be its new equivalent. Run migration on the old pools to move the data off to the new pools. The new migrate stg command with a duration will drip feed this over time. 6. Finally, when everything is copied, run del vol on each of the old copypool volumes (discardd=yes will be needed) and any old primary pool volumes (discardd=no) that need it, and clean up old definitions. Hope that helps Regards Steve. > -----Original Message----- > From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] > On Behalf Of Laura Mastandrea > Sent: Tuesday, 28 March 2006 12:01 AM > To: [email protected] > Subject: [ADSM-L] TSM SERVER MIGRATION from STK ACSLS tape > library to IBM 3584 > > > > Are there procedures for migrating a TSM server over a period > of time from one tape library system to another?
