It's not wrong, it just means you are doing something manually that
normally
ADSM takes care of automatically.

If you have only 1 tape drive, then you must do reclaims by using MOVE DATA
to shuffle data from tape back to disk, then back to tape.

If you have more than 1 tape drive, ADSM should do it for you.

How many tape drives do you have?

Check the mountlimit for the device class:  q devclass * f=d

Kelly, can you think of anything else that would prevent reclaims from
happening automatically?
