Hello Rob!

Your Options in the device class:
Set your Estimated Capacity under the maximum value of your tapes. TSM uses
this value only for calculating tha capacity of your storagepool and so on
...
Set your maximum capacity to 0. TSM writes until the tape is full! So TSM
can detect the maximum value itself!
Set compression to yes. Than TSM activates the IDRC compression of your
3590 drive. This should work then!
