Hello, everyone. We run a TSM server v 5.1 level 5.4 on an AIX 4.3 machine. The AIX admins here have been upgrading their other servers to AIX v 5.1 with the 32 bit kerenl. We've found that on the AIX upgraded machines that TSM restores and HSM recalls from tape are performing horribly, with a transfer rate of 200k every 20 - 30 seconds. To confuse the issue more, we've found that with restores work with test files that were backed up and then immediately restored, without being flushed to tape. Backups perform as they always have. Restore performance is great on machines that have not had the OS upgraded.
We've tested one server before and after the upgrade and saw the performance drop with the upgrade. The servers are running TSM clients at 5.1.0.6. Has anyone seen these symptons before? -- Michael Lambert <[EMAIL PROTECTED]>
