WHAT THE AUTOLOADER RETURNS
19.3.5 STORAGE ELEMENT DESCRIPTOR
Each of the autoloader’s seven cartridge cells is a storage element. If the
autoloader’s Limit Number of Cells option is turned on, or if the MaxStor and
MaxStorAddr fields are set on the MODE SELECT Unique Properties Page (see
page 9-7), the number of storage elements reported is equal to the number of
addressable cells specified. See the Magnum 1x7 LTO Autoloader Product Manual
for more information about changing the number of addressable cells from the
LCD.
Note: If both the Fixed Cleaning Cell and Auto-Clean flags are set to 1 on the
MODE SELECT Cleaning Configuration Page (see page 9-12) and if the
InvACIn bit on the MODE SELECT Unique Properties Page (see page 9-9)
is set to 1, the cell with the highest address is not be available to SCSI. In
this case the maximum number of storage elements is six.
For each storage element, the autoloader returns the following storage
element descriptor.
