[gpfsug-discuss] TSM and re-linked filesets

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
