Field descriptions:
Element Type Code:
The Element Type Code field specifies an element type specification as defined in the Read
Element Status command. If the Send Action Code field indicates a translate operation, this field
indicates the element types to be searched. If the value is zero, all element types are candidates
for a translate operation. If the Send Action Code does not indicate a translate, this field shall be
treated as reserved.
Element Address:
The Element Address field gives the media changer element address whose interpretation
depends on the Send Action Code field. When the Send Action Code field is a translate, the
Element Address field gives the starting element to be examined for the search operation. When
the Send Action Code field is assert, replace, or undefined, the Element Address field gives the
specific Element Address where the volume tag information for a volume is to be modified.
Send Action Code:
The Send Action Code field gives the function to be performed by this command as specified in
next table:
