Does anyone know how to determine if a specific tape is in use?

If once I determine that nothing is using a tape, how does one remove it
from the drive, etc?

I'm concerned with tape D00634 and V00313, as these device file timestamps
are old:

# tpconfig -d: (truncated)
 11   Drive11                /dev/rmt/c5t1d0BESTnb    hcart    Yes       UP
        TLD(1) Definition       DRIVE=2
 12   Drive12                /dev/rmt/c20t2d1BESTnb   hcart    Yes       UP
        TLD(1) Definition       DRIVE=3

# ls -l  /dev/rmt/c5t1d0BESTnb
crw-------   2 root       bin        205 0x0510c0 Dec 13 14:50
/dev/rmt/c5t1d0BESTnb

# ls -l /dev/rmt/c20t2d1BEScrw-------   2 root       bin        205 0x1421c0
Dec 13 18:01 /dev/rmt/c20t2d1BESTnbTnb

I'm also getting a lot of error (52)s ("timed out waiting for media manager
to mount volume (52)".  I don't know if these are related or not.

Thanks,
