WHAT THE AUTOLOADER RETURNS

15.3.2 ELEMENT STATUS PAGE

The autoloader returns one Element Status page for each group of element

descriptors of the same type (that is, it returns one page for each of the

following: cartridge loader, cartridge storage locations, and tape drive). The

Element Status page is returned only if there is at least one Element Descriptor

also being returned.

Element Type Code – Byte 00

This field indicates the specific element type (see page 15-2) being reported by

the element descriptor.

PVolTag – Byte 01, Bit 7

This field indicates if primary volume tag (bar code label) information is

present, as follows:

0 – Volume tag bytes are omitted from the element descriptors

1 – Volume tag information is present

AVolTag – Byte 01, Bit 6

The autoloader does not support alternate volume tags. The value reported for

this field is 0.

Element Descriptor Length – Bytes 02 and 03

This field indicates the total number of bytes contained in a single element

descriptor, as follows:

 If the descriptor being returned is for either the medium transport element

(the cartridge loader) or a storage element (cartridge cell), the length is either

52 bytes (if the VolTag bit is 1) or 16 bytes (if the VolTag bit is 0).
