Hello everybody, It seems like TSM performance problems will neer end!!!
Here is the new problem: The customer is running TSM 4.2.1.0 on a Windows 2000 server machine . An IBM rack case 82XX which contains a Quantum DLT8000 tape drive is connected to the server. The driver version for the Quantum DLT drive is 1.5 and is installed on the W2K machine. We tried a backup of 350MB on the local server with the Windows 2000 Backup utility and it took us approximately 75 seconds . Next , we tried the same Backup from TSM using its Device Driver and it took us about 9 minutes . We tried switching TSM to use the Native device driver but still we got the same performance result . So we upgraded to 4.2.2 ; In the Device Manager for TSM,we can see that TSMSCSI.exe is upgraded to 4.2.2.25 and the ADSMSCSI.sys is 4.2.2.3 . The server has a version of 4.2.2.25 . Still , we obtained poor backup performance . We suspected that maybe it was a database bottleneck ( eventhough it is still empty) ; so we tried the same Backup using TSM but the destination was on the HardDisk. The performance was good and the backup finished within 75seconds . So, we can eliminate the database problem. Also, we noticed with version 4.2.2.0 that it is crashing frequently . It was exiting abnormally . On the site of tivoli, the latest version of TSM server is 4.2.2 . We do not have the 5.1 release . does anyone have a suggestion? thx a lot Sandra __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo!
