David,
Check your definition for the 3590 device class. Make sure that
format=3590c or format=drive. A 'q vol' on 3590 volumes will return an
estimated capacity of 10gb until the actual data stored on the volume goes
beyond that number. In that case, the estimated capacity will then reflect
the actual data bytes stored until the volume is full. After that the
number will again decrease as data on the volume gets expired.

Have a nice day or whatever's left of it.
