The information in the SCSI Reservations screen is described in
the following table.
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.
