Neil and Muthyam. Got it! Thanks for your kind clarification.
Gus >>> [EMAIL PROTECTED] 8/11/2004 11:57:52 AM >>> Gus I'm not sure I've understood your setup. Are you saying you have a primary disk pool, a primary tape (LTO) pool as the destination for migration from the disk pool, and a copy tape (LTO) pool? My guess is that you want migration processing on the server to simultaneously write data to both the primary and copy tape pools, but I don't believe this is possible. My understanding of simultaneous writes is that it is only possible during client operations - a client session will mount tapes from multiple storage pools. The Administrator's reference guide says "the server simultaneously writes data when a client backup, archive, or migration operation stores data to the primary storage pool". However I believe the reference to migration in this context is talking about HSM-style client migrations only. In order to simultaneously write to both the primary and copy tape pools, you are going to have to bypass the disk pool completely and have your clients write direct to tape. An intermediate solution would be to set a maxsize threshold on the disk storage pool, so large files are simultaneously written to primary and copy tape pools. Small files would go to disk and then be migrated to primary tape and separately copied to copy tape. Does anybody else agree? Regards Neil Schofield Yorkhire Water Services Ltd.
