Hi All, I have a performance problem when doing Space-Reclaamtion, or backup storage pool, when TSM is copying data from one tape drive to the other. Environment: Windows 2K server, TSM 4.2.1.15. Library, Compaq MSL5026, with 2 SDLT drives (Single Module Library). SCSI Controller, Compaq 64-bit/66Mhz Dual Channel Wide Ultra3 SCSI Adapter (Compaq version of Adaptec 39160)
Moving data from Disk to Tape runs with expected speed (8-10 MB/s). >From Tape to tape speed is around 2MB/s. (50GB takes about 7-8hours.) Does anyone know why? It is killing my daily operations. Mvh Geirr G. Halvorsen TSM Enterprise Backup Specialist WMdata Danmark A/S
