INENAB This field is sent as 1 to indicate that the import/
export element supports movement of media into the
scope of the media changer device.

export element supports movement of media out of

Access When set to 1 it indicates that access to the element by
a medium transport is allowed. When set to 0 it
indicates that access is denied. This may occur if the
user is performing an operation from the front panel
or Ethernet connection that prohibits access from
SCSI.
IMPEXP When set to 1 it indicates that the unit of media in the
import/export element was placed there by an
operator. When set to 0, it indicates that it was placed
there by the medium transport element. When the
Except bit is 1, the value of the IMPEXP bit is invalid.
