RWWP bit
0 A reject write without protection (RWWP) bit set to zero specifies that the device server shall process write commands that are specified
to include user data without protection information (e.g., a WRITE(10) command with the WRPROTECT field set to 000b (see 3.60)).
1 A RWWP bit set to one specifies that the device server in a logical unit that has been formatted with protection information shall termi-
nate with CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and the additional sense code set to INVALID FIELD IN
CDB any write command that is specified to include user data without protection information.
AUTOLOAD MODE field
The AUTOLOAD MODE field specifies the action to be taken by a removable medium device server when a medium is inserted. For devices
other than removable medium devices, this field is reserved.
Table 382 shows the usage of the AUTOLOAD MODE field.
READY AER HOLDOFF PERIOD field
NOTE This field has been declared obsolete by the T10 committee and are not supported.
BUSY TIMEOUT PERIOD field
The BUSY TIMEOUT PERIOD field specifies the maximum time, in 100 milliseconds increments, that the application client allows for the device
server to return BUSY status for unanticipated conditions that are not a routine part of commands from the application client. This value may
be rounded down as defined in
Clause 2.3. A 0000h value in this field is undefined by this manual. An FFFFh value in this field is defined as an
unlimited period.
EXTENDED SELF-TEST COMPLETION TIME field
The EXTENDED SELF-TEST COMPLETION TIME field contains advisory data that is the time in seconds that the device server requires to com-
plete an extended self-test when the device server is not interrupted by subsequent commands and no errors occur during processing of the
self-test. The application client should expect this time to increase significantly if other commands are sent to the logical unit while a self-test is
in progress or if errors occur during the processing of the self-test. Device servers supporting SELF-TEST CODE field values other than 000b for
the SEND DIAGNOSTIC command
(see 3.46) shall support the EXTENDED SELF-TEST COMPLETION TIME field. The EXTENDED SELF-TEST COM-
PLETION TIME field is not changeable.
