De-gaussing is the only practical way to erase a significant quantity of
tapes, and degaussing will render a number of modern tape formats
useless forever. One of them is LTO. Not sure about 3x9x. (It's

Are you seeing anything in the server activity log?
One issue that I ran into was that the logs and database should be stored in
different storage pools when using the include logs option. Otherwise the

Did you examine the TSM Server activity log closely?
Was there a problem where a tape did not get mounted in time?
How many stripes are you using for the backup?
If you are using multiple stripes and one of those stripes
is waiting for the TSM server to mount a tape, it can cause this.

I don't see anything in the activity log. The backups are going straight

This sounds like PMR#64846-122, which is still open after months of

3590 tapes are where IBM servo tracks were first invented
(unless it was 3570, I may be mistaken). 3592 and LTO are follow-on
technologies built from those first ones.
De-guassing shouldn't be the only way this could be done. It

The tape erase function is written up in the tape driver prog ref.

I didn't say it was the only way. I said it was the only practical way.
The erase function takes too long per tape to be used in bulk.

In the Windows client, you can go to the GUI and under 'View policy

Avy,
There is no direct way of finding a node's management class bindings, as
it is defined at the client's include-exclude list.
Also, A node's data can be bound to multiple management classes.

You can get the same information form the web client of the Linux host.
