Then, notice the volumes in the LTO3POOL are LTO3 tapes, 800GB capacity,
compressed that is, and should be 400GB native.
You didn't post the output of 'q devc LTOCLASS2 f=d' - the value of
FORMAT should be 'ULTRIUM3C' if you want to use compression. The
"estimated capacity" gives an idea about the tape's capacity, but doesn't
force compression, in fact you can set it to anything you want.
Maybe herein lies the problem, format is "DRIVE". We've had an LTO2
library on the same server for two years, and that is LTOCLASS1, and that
is just fine (220/400), and that also has a format value of 'DRIVE'. The
LTO3 library is new as of a few weeks ago, and I didn't notice the
capacity issue until one the tapes filled up. Here is the output:

Do I need to declair a new value for that parameter? If so, then does that
mean the data on the media needs to be moved off before hand?
Thanks!
