Tandberg SLR Autoloader SCSI Functional Specifications

Byte Count of Descriptor Data Available

The byte count of descriptor data available field indicates the number of
bytes of element descriptor data available for elements of this element type
meeting the request of the CDB. The value shall not be adjusted to match
the allocation length available.

Element Address

The element address field gives the address of the medium changer element.

Except

An exception (Except) bit of one indicates the element is in an abnormal
state. An Except bit of zero indicates the element is in a normal state. If this
bit is one, information on the abnormal state may be available in the
additional sense code and additional sense code qualifier bytes.

Full

A full bit of one indicates that the element contains a unit of media. A value
of zero indicates that the element does not contain a unit of media.

Additional Sense Code

The additional sense code field provides specific information on an abnormal
element state. The values in this field are as defined for the additional sense
code of the REQUEST SENSE data.

Additional Sense Code Qualifier

The additional sense code qualifier field provides more detailed information
on an abnormal element state. The values in this field are as defined for the
additional sense code qualifier of the REQUEST SENSE data.

SValid

A source valid (SValid) bit value of one indicates that the source storage
element address field and the invert bit information is valid. A value of zero
indicates that the values in these fields are not valid.

Invert

An invert bit value of one indicates that the unit of media in this element
was inverted. A value of zero indicates that no inversion occurred. This bit
shall always be set to zero.

Source Storage Element Address

The source storage element address field provides the address of the last
storage element this unit of media was moved from. This field is valid only if
the SValid bit is one.
