Element Type Code Definitions
The format of Element Status data is defined in the SCSI-2 specification. The
following sections show the information returned for the medium changer. The
Element Status data is made up of a header, and one or more Status Pages (for each
element type). The Status Pages are made up of a header and one or more element
descriptors (one for each element address). The data shown assumes the CDB was
specified in such a way that all descriptors for a given element type would be returned.
The Primary and Alternate Volume Tag functions are not supported, so the flags
indicating these functions in the Element Status Pages (below) are always set to zero.
