Table 4.22

Code	Status of unit

00100	BUSY
	A target or logical unit cannot accept a new command.
	∙ The logical unit is executing processing.
	∙ The target is executing processing on a specified logical unit or other logical unit.
	∙ The target intends to report to an other initiator the sense data of a specified logical unit.
	∙ The target intends to report to an other initiator the sense data of a logical unit that was not specified.
	∙ The target intends to report the status to any initiator.

01100	RESERVATION CONFLICT
	∙ The specified unit is already reserved by another initiator.

When a target is released from the BUSY status, it will not issue a notification of the release. Therefore initiator needs to check the status of units periodically and needs to issue the command again.

4.6 Messages

This section describes the detection of an ATN signal and explains the types of messages supported by this scanner.

4.6.1ATN detection

The following table summarizes the timing at which this scanner detects and ATN signal.

	Table 4-23

Phase	ATN detection timing

SELECTION	Immediately before a phase change

COMMAND	Immediately before a phase change

DATA OUT	Immediately before a phase change

DATA IN	Immediately before a phase change

STATUS	Immediately before a phase change

MESSAGE OUT	Upon each reception of a message

MESSAGE IN	Upon each transmission of a message
