We have two drives that show state unknown when queried with f=d. According
to TSM:

"Unknown The drive begins in drive state unknown as a result of being
defined, as a result of server initialization, or as a result of having its
status updated to online."

We have had to update the status of these two drives to online after some
tapes had knocked them offline.

The drives are now online but TSM is not using them.

Is there a way to change the drive state to empty or ready for operation?
