Fibre Channel Interface Manual, Rev. D 233
12.13.8 Mode Sense/Mode Select Control Mode page (0Ah)
The Control Mode page provides controls over several SCSI-2 features which are applicable to all device types
such as tagged queuing, extended contingent allegiance, asynchronous event notification, and error logging.
See the individual drive’s Product Manual, Volume 1, Mode Sense Data table for changeable values.
Field definitions (listed alphabetically)
Busy Timeout Period
The maximum time, in 100 millisecond increments, that the initiator allows for the target to remain busy for unanticipated
conditions that are not a routine part of commands from the initiator. This value may be rounded down as defined in Section
4.8 of this manual.
0000h Undefined.
FFFFh Unlimited period.
DQue (Disable Queuing)
Drives supported by this manual require this bit to be set to zero (0).
1 Tagged queuing is disabled on the disc drive. This is not a valid value for the drives supported by this manual.
0 Tagged queuing is enabled.
Extended Self-Test Routine Completion Time
This field contains an advisory parameter that the application client may use to determine the time, in seconds, that the
device server requires to complete the extended device self-test when the device server is not interrupted by an application
client and no errors occur during execution of the device self-test. The application client should expect this time to increase
significantly if other commands are sent to the logical unit while a test is in progress or if errors occur during execution of
