Production side: TSM Server: 5.3.3 on AIX 5.3 Tape Library: 3584 with 8 LTO3 drives DB2 database: 8.2, 1.2TB with 7 backup drives, backup time 1.2 hour offisite copy, 2 processes, with 4 drives.
DR site: TSM Server: 5.3.3 on AIX 5.3 Tape Library: 3584 with 4 LTO3 drives My problem is, when I did twice restore test, the first time it used 4 drives to do restore, used 5 hours to restore. The second test, it only used 2 drives to do restore and it used 12 hours. My question is, how can I ensure the restore can constantly use 4 drives to do restore? TIA.
