Could you do something really nasty in the tsm db2 database to update the paths?

A quick Google has given me the answer I dreaded:

“Attention: If you are using the TSM Backup-Archive client you must use caution 
when you unlink filesets that contain data backed up by TSM. TSM tracks files 
by pathname and does not track filesets. As a result, when you unlink a 
fileset, it appears to TSM that you deleted the contents of the fileset. 
Therefore, the TSM Backup-Archive client inactivates the data on the TSM server 
which may result in the loss of backup data during the expiration process.”

So I need to relink it to the original place I think. Oh well. Not a disaster.

This is more a TSM question than GPFS but it involves GPFS to a point so I hope 
I’m ok asking this.

I’ve unlinked a fileset and relinked it at a different junction point. Will 
this cause TSM to see a “new” fileset and back up all its content? This is very 
undesireable so if I need to put it back where it belongs then I need to do 
this before tonight.

GPFS 3.5 and TSM 7.1.

Does anyone know?

Cheers

Richard
