SEPTEMBER 2005 MAGNUM 1X7 LTO AUTOLOADER
9-13
COMMAND STATUS
Notes:
 When both the FixEnbl and the Auto bits are set (that is, when a cell is reserved
for a cleaning cartridge and the autoloader 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).
 If the InvACIn bit on the Unique Properties Page (see page 9-9) is set to 1, the
valid value for the Number of Storage Elements field on the Element Address
Assignment Page (1Dh) for MODE SELECT and MODE SENSE is one less than
when there is no Fixed Autoclean cell.
 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 autoloader 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 autoloader returns a status byte after processing the MODE SELECT
command. This section describes when each type of status byte might be
returned.
Good
The autoloader 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
The autoloader returns Busy status when it is processing a command for a
different initiator or when the autoloader is in the process of aborting a motion
command.
