Time Monitoring Feature; Retry Count Setting For Reselection Phase - Fujitsu MAN3184 SERIES Specifications

1.6.11

Time monitoring feature

The IDD has a time monitoring feature for the SCSI bus to prevent the hang-up of the SCSI bus in
the case that the IDD cannot receive a response from the INIT in the RESELECTION phase.
The IDD monitors the response from the INIT (BSY signal) in the RESELECTION phase. When
the IDD cannot receive the response within a specified period (250 ms), the IDD executes the
timeout process (see Section 1.6.4) and releases the SCSI bus once. After that the IDD executes
the retry process of the RESELECTION phase (see Section 3.1).
The user can select the number of retries of the RESELECTION phase by the CHANGE
DEFINITION command.
