Hi Matt,
My understanding is this....
 
If a volume is SUSPENDED the system will not write to it until all the
backup images on that volume have expired. (either automatically or if
manual expiry which can be carried out using the command tool BPEXPDATE)

If a volume is frozen the system will not write to it even after all the
backup images on that volume have expired. This means there could well be a
problem with the Media. When expired the media report in Netbackup will say Frozen Expired. If I get too many frozen tapes, I can unfreeze and use them again. But if they continually fail, remove them from the library.

Subject: [Veritas-bu] Suspend or Freeze media

We are trying to phase our our LTO 2 tapes as we go to LTO 3. My thought is that I will freeze or suspend the tapes and when they expire we can remove them from service. Does this seem logical? Also, is there a way to freeze a range of tapes? I do not have a good understanding of freezing/suspending media. From what I read it appears that once a frozen tape expires it comes back into service and a suspended tape never expires. I am interested in knowing thoughts on the best way to remove the media from service.
