Delete and redefine TSM log

[DRNERD]

Due to a recent performace issue our hardware vendor has asked that we re-define the array that we are using for the TSM log. The log sits on it's own 36GB mirrored array. Currently the log is 13% utilized.

I am looking for the best way to offload/reset the log before the TSM server is halted, so that I can delete the log and redfine it after the disk array is redefined with out compromising my database.

How big is your log? I am presuming that by saying it is 13% utilized that it is not 13% of 36 GB or 4.68 GB. Remember that prior to TSM 6.1, your log limit is only 13 GB.

All you have to do is:

- stop all sessions/processes
- backup the database; the log should go to zero
- halt TSM
- redo your disk
- redefine the log volumes
- change the configuration files if needed
- restart TSM.

Sorry, it is defined at 9GB

Thanks Ed,

This is what I was thinking, but I wanted to make absolutely sure I could get my DB back.
