Unit reservations

Reservation	or 0 if it is not) and the host’s ID, if the library is
	reserved.
Elem reservations
Elem Addr	The address of the element.
Elem Type	The category of elements. There are three
	categories: CHM, Drive, and Slot.
Host ID	The SCSI ID of the host that currently has the
	element reserved.
Res ID	The ID that the element is reserved under. This is
	a number assigned to the element by a host when
	the reservation was made. If there is no
	reservation, the Res ID and Host ID columns
	display “ -NONE-.”

SCSI sense data

When an error or change of state occurs, the application software can issue a SCSI REQUEST SENSE command to the library to obtain information. Some of this information, called sense data, is displayed on the SCSI Sense Data screen. Sense data provides information to help diagnose problems with the library. For more detailed information about SCSI sense data, refer to the EXB-440 and EXB-480 8mm Libraries SCSI Reference.
