If a cartridge is FULL, does the estimated capacity include files that have
been expired on that cartridge? E.g. assuming a tape takes time to fill up,
it's possible some of the files on that tape may expire before the tape
reaches FULL status. It's also unlikely the space has yet been reclaimed.
Once the tape reaches FULL status does the estimated capacity include those
files that have expired?

Divide the amount of data on your FULL tape volumes by the native capacity.
Here's a sample SQL statement. You'll need to filter it for your tape
storagepools and only FULL volumes.

select volume_name,cast(est_capacity_mb/xxxx as decimal(3,1)) from volumes

Use these values for xxxx:

        3590B           10240 (10GB native)
        3590E           20480 (20GB native)

Extended length cartriges double the value.

Hello!

Is there any way to find out how much compression I am getting on a IBM 3494
library?

Thanks.

Mahesh
