"SHOW DEVICE /FULL tape:" quirk?

So, there I was with my new (to me) $10 DLT drive (faster than a
TK50, it is), when I made the mistake of actually reading the output
from SHOW DEVICE /FULL ...

Mounted:

Magtape ALP2$MKB200:, device type Quantum DLT4000 CPQ DRV, is online, allocated,
deallocate on dismount, mounted foreign, record-oriented device, file-
oriented device, served to cluster via TMSCP Server, error logging is
enabled, controller supports compaction (compaction enabled), device
supports fastskip (per_io).

Not mounted:

Magtape ALP2$MKB200:, device type Quantum DLT4000 CPQ DRV, is online, record-
oriented device, file-oriented device, served to cluster via TMSCP Server,
error logging is enabled, controller supports compaction (compaction
nabled), device supports fastskip (per_io).


"(compaction nabled)"???


VMS Alpha V8.2 shown above. Things look similar at V7.3-2:

Magtape ALP$MKB200:, device type EXABYTE EXB-85058HE-0000, is online, allocated,
deallocate on dismount, mounted foreign, record-oriented device, file-
oriented device, served to cluster via TMSCP Server, error logging is
enabled, device is busy, controller supports compaction (compaction
nabled), device supports fastskip (per_io).

(Of course, the activity LED on the Eliant drive always shows green
instead of amber, so it seems unlikely that it's actually doing
compaction.)
