I think you mean volumes on your system, not TSM volumes. Without running another backup, I don't believe you can change the retention on specific volumes. If you change the retention policy in the management class for the node, all of the data will be retained in that way. You are correct: if you create a new management class with the desired retention, then include those volumes requiring that retention in your dsm.opt file, running another backup will rebind those volumes to the new management class. That is the only way to be discrete to the volume level.

How do you know what is on those volumes? Need more information... Is this copy pool data? Is it data for a single node and you know what is on it because of collocation?

I do not want to change all of the volumes on a node, only select volumes. I know that retention is determined by the management class and if you change the management class it rebinds on the next backup but I need to be able to change it on existing volumes without backing up again or changing it on all of the data. Is there any way to do this and if so, how can I accomplish this quickly. We were informed today and they want it by tomorrow. Thanks for the help. Debbie Haberstroh Server Administration
