SEPTEMBER 2005 MAGNUM 1X7 LTO AUTOLOADER
10-15
WHAT THE AUTOLOADER RETURNS
Auto – Byte 02, Bit 1
This bit indicates whether the autoloader will use an available cleaning
cartridge to clean the drive automatically when required, as follows:
0 – Do not automatically clean drive.
1 Automatically clean drive when required if a cleaning cartridge is available.
This bit is only valid when the FixEnbl bit is 1.
FixEnbl – Byte 02, Bit 0
This bit indicates whether the autoloader has a fixed cell reserved for a
cleaning cartridge, as follows:
0 – No cleaning cartridge reservation
1 – Highest numbered Storage Element reserved for cleaning cartridge
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 Magnum 1x7 LTO
Autoloader Product Manual more information about the autoloader’s Autoclean
option.
Notes:
When both the FixEnbl and the Auto bits on the Cleaning Configuration Page are
set to 1 (that is, when a cell is reserved for a cleaning cartridge and the
autoloader is configured to automatically handle cleaning) and if the InvACIn bit
on the Unique Properties Page (see page 9-9) is set to 1, 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 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.
