Table 1.21 Retry Count Setting For Reselection Phase - Fujitsu MBA3073 SERIES Technical Manual

The HDD has a time monitoring feature for the SCSI bus to prevent the hang-up of the SCSI bus
in the case that the HDD cannot receive a response from the INIT in the RESELECTION phase.
The HDD monitors the response from the INIT (BSY signal) in the RESELECTION phase.
When the HDD cannot receive the response within a specified period (250 ms), the HDD executes
the timeout process (see Section 1.6.4) and releases the SCSI bus once. After that the HDD
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.
