1.5UNIT ATTENTION Condition

The UNIT ATTENTION condition is a function used to notify the INIT asynchronously of an event (status change) that has occurred in the TARG or logical unit.

1.5.1Generation of the UNIT ATTENTION condition

Events which cause a UNIT ATTENTION condition to be generated are one of the following.

(1)When power on, RESET or TARGET RESET occurs

If the IDD’s power is switched on, the IDD enters the RESET condition or is reset by a TARGET RESET message, this UNIT ATTENTION condition is generated for all the INITs, regardless of whether the disk drive is in the ready state or not.

(2)Mode parameters changed (changed by another INIT)

If the parameters specified in the MODE SELECT or MODE SELECT EXTENDED command are changed by any INIT, a UNIT ATTENTION condition is generated for all the INITs other than the INIT which changed the parameters.

(3)Commands cleared by another INIT

Commands which are being executed or which are queued are cleared if one of the following events occurs, and this UNIT ATTENTION condition is generated.

•The CLEAR TASK SET message is issued by any INIT.

•Tagged queuing is prohibited by a MODE SELECT or MODE SELECT EXTENDED command (Page A send) from any INIT. (DQue = “1”)

•The sense hold state of an INIT is released when “1” is specified in the QErr bit of MODE SELECT parameter page A.

However, the IDD does not enter the UNIT ATTENTION condition hold state for an INIT that issues a CLEAR TASK SET message, an INIT that issues a MODE SELECT or MODE SELECT EXTENDED command, or an INIT that releases the sense hold state.

(4)Changed operating definition

When the operation mode is changed by the CHANGE DEFINITION command, the UNIT ATTENTION condition is generated for all INITs.
