CHAPTER 9—MODE SELECT (15h)
When the FixEnbl is set to 1, the storage element with the highest element
address is reserved for a cleaning cartridge. That storage element is then
unavailable for storing a data cartridge. Refer to the Product Manual more
information about the library’s Autoclean option.
Notes:
When both the FixEnbl and the Auto bits are set (that is, when a cell is reserved
for a cleaning cartridge and the library is configured to automatically handle
cleaning) the cell reserved for the cleaning cartridge, with the highest element
address, is removed from the cell geometry.
The status of reserved cell is not reported in response to the READ ELEMENT
STATUS or READ ELEMENT STATUS WITH RANGE commands.
The reserved element address is invalid for motion commands (for example,
MOVE MEDIUM, POSITION TO ELEMENT).
The handling of the element address reserved for the cleaning cartridge is
unchanged on all LOG SELECT and LOG SENSE log pages.
When a MODE SELECT command changes the values for both the FixEnbl and
the Auto bits (either both turned on or both turned off), the library returns NOT
READY TO READY Unit Attention (ASC/ASCQ of 28h/00h) message after the
successful completion of the command.
9.3 COMMAND STATUS
The library returns a status byte after processing the MODE SELECT
command. This section describes when each type of status byte might be
returned.
Good
The library returns Good status when it is able to process the command
without errors (that is, when the requested MODE SELECT parameters have
been copied over the current MODE SELECT settings and, if requested, the
saved MODE SELECT settings).
Busy
Busy status indicates that the library is temporarily unable to accept a
command from this initiator. The initiator may retry the command later.
Reservation Conflict
The library returns Reservation Conflict status when it is reserved by a
different initiator. See Chapter 20 for more information about the RESERVE
command.
Check Condition
The library returns Check Condition status for the following reasons:
