How to resolve warning "There are not enough scratch volumes available."?

[Hsing1]

The TSM daily report show warning "There are not enough scratch volumes available".
How can I extend the scratch volumes?
It seems the scratch number is not the Number of scratch volumes in TS3500 or TS3310.

Hi !

You should recheck and add new Tape to your Library

Add more scratch tapes, or since you have 1 scratch, start doing reclamation with 50% at first, if you need more scratch, you can reclaim again more aggressively (40, 30, 20, 10). Also make sure expiration runs daily and successfully.
