SCSI Interface
The StorDT, StorIE, StorST, and StorMT fields indicate whether an
element of the indicated type (DT, IE, ST, or MT) is capable of storing a
tape cartridge.
The XX->YY fields indicate whether a transfer from an element of type
XX is possible to an element of type YY. A one in any of these fields
indicates that all Move Medium commands where the source element
is type XX and destination element is type YY are supported. A zero in
these fields indicates the move may or may not be valid depending on
the particular element requested.
The library does not support the Exchange Medium command. Bytes
12 through 15 in this parameter page contain the individual fields
specifying the library exchange capabilities. Since the library has no
exchange capability, all of these fields are zero.
The format of the Vendor Unique Page 20h is shown in Table 22.
