The Tuning guide recommends (for AIX servers) using raw LVs for db and log vols only. They recommend using JFS for stgpool volumes.

Hi *,
I use on both server logical volumes and jfs-filesystems. All (DB, log and disk pool) are on jfs-filesystems.
Is it better when I change to RAW devices?

Are you using RAW volumes or logical, file system mounted volumes for DB, log, and disk pool? RAW volumes make a HUGE difference. You should also have your client's NIC's forced to 100/Full (the ones using fastethernet), don't let them auto negotiate, kill's backup performance.

Hi *,
our TSM environment is very slow (backup from the clients and the backup storage pool from the first to the second server). So I would like to describe our environment once roughly: We have 2 TSM server (Version 5.1.8) which runs both on AIX boxes with AIX 5.1. On the first server is an 3494 library (with 4 3590 drives) connected and on the second server an 3583 (with 3 LTO Ultrium1 drives).
The clients (AIX-clients and Windows clients) are connected over fastethernet or gigaethernet. First TSM server has both adapter (fast and giga). The connection between the first and the second TSM server is gigaethernet.
Can you give me some tips to increase the performance? I think that are some TSM and AIX options (TCPWindowsize etc on TSM side and son no-Paramter on AIX site).
What is a good start for this options?
Best regards, Frank Mueller
