Meaning
The library does not return block descriptors even if requested to do so. This is
not an error condition. It simply returns a block descriptor length of 0.
Requests current mode parameter values.
Requests changeable parameters. The requested mode pages are returned,
but rather than parameter values, bits are set to 1 if changeable or 0 if not.
Requests default values.
Requests saved values. If a page has not been saved, default values are
returned.
Requests the library return all available mode pages.
Requests element address assignment page only.
Requests transport geometry parameters page only.
Requests device capabilities page only.
Specifies the number of bytes the initiator allocates for data returned. Zero
indicates no mode data is to be transferred; this condition is not considered
an error. The library terminates the data in phase when it transfers either the
number of bytes specified by the allocation length field or all of the available
mode parameter data, whichever is less. The data length for all mode
parameter pages returned by the library is 48 bytes (30h).
