Field descriptions:
First Medium Transport Element Address:
By means of this field the host can specify the address of the accessor cartridge handler.
Number of Medium Transport Elements:
By means of this field the host can specify the number of robotic cartridge handlers within the
library. If the Number of Medium Transport Elements is greater than the default value returned in
the Mode Sense parameter data, the library shall return a Check Condition.
First Storage Element Address:
By means of this field the host can specify the starting address for the cartridge storage locations.
Number of Storage Elements:
By means of this field the host can specify the number of cartridge storage locations. If the
Number of Storage Elements is greater than the default value returned in the Mode Sense
parameter data, the library shall return a Check Condition.
First Import/Export Element Address:
By means of this field the host can specify the address of the import/export element.
Number of Import/Export Elements:
By means of this field the host can specify the maximum number of import/export elements. If the
Number of Import/Export Elements is greater than the default value returned in the Mode Sense
parameter data, the library shall return a Check Condition.
First Data Transfer Element:
By means of this field the host can specify the starting address of the installed tape drives.
Number of Data Transfer Elements:
By means of this field the host can specify the number of tape drives installed. If the Number of
Data Transfer Elements is greater than the default value returned in the Mode Sense parameter
data, the library shall return a Check Condition.
Note:
The actual number of installed elements cannot be changed by the field values in the Element
Address Assignment page. Specifying a value other than the specified number returns a Check
Condition status with the Sense Key set to ILLEGAL REQUEST.
Transport Geometry Parameters page (1Eh)
The Transport Geometry Parameters Page is provided in the SCSI-2 command set to determine whether
each medium transport element is a member of a set of elements in a robotic subsystem, and if the
medium transport is capable of media rotation. The initiator cannot change this information.

3 Member Number in Transport Element Set (0)
Field descriptions:
Rotate:
Rotation of media is not an implemented feature, so the value returned for this field bit is 0.
Member Number in Transport Element Set:
This field indicates the specific transport element in the system to apply this descriptor to. The
library has only one transport element , so the value returned for this field is 0.
