CHAPTER 9—MODE SELECT (15h)

First Storage Element Address – Bytes 06 and 07

This field identifies the starting address of the cartridge storage locations. The

default starting address is 01h (1). When assigning new addresses, you assign

the first number and the autoloader automatically assigns the others

sequentially.

Number of Storage Elements – Bytes 08 and 09

This field identifies the maximum number of cartridge storage locations within

the autoloader. The maximum valid value for this field is 07h (7).

The number of storage elements is fixed and cannot be changed using the

MODE SELECT command. See the Magnum 1x7 LTO Autoloader Product

Manual for more information about limiting the number of cells used by the

autoloader.

Note: If both the Fixed Cleaning Cell and Auto-Clean flags are set to 1 on the

Cleaning Configuration Page (see page 9-12) and the InvACIn bit on the

Unique Properties Page (see page 9-9) is set to 1, the cell with the highest

address may not be available to SCSI. In this case the maximum number of

storage elements is six and the value for this field is 06h.

First Import/Export Element Address – Bytes 10 and 11

This field identifies the address of the entry/exit port. The autoloader does not

have an entry/exit port. The value for this field must be 0.

Number of Import/Export Elements – Bytes 12 and 13

This field identifies the total number of locations used for importing and

exporting cartridges to and from the cartridge storage areas. The autoloader

does not have an entry/exit port. The value for this field must be 0.

First Data Transfer Element Address – Bytes 14 and 15

This field identifies the starting address of the installed tape drive. The

autoloader has only one tape drive with a default address is 52h (82).

Number of Data Transfer Elements – Bytes 16 and 17

This field identifies the number of tape drive installed in the autoloader. The

autoloader has only one tape drive. The valid value for this field is 0 or 1.

Note: The actual number of tape drives installed cannot be changed by this field

because the autoloader automatically determines the number of tape

drives during power-up. It is not an error to specify a value that is different

from the actual number of tape drives installed, as long as that value is 0 or

1. If the value is not 0 or 1, the autoloader returns Check Condition status

with the sense key set to Illegal Request.
