Self-tests of each type are conducted in either of the following two modes: 

• 

Foreground mode 

• 

Background mode 

The subsequent sections explain both modes in detail. 

Before the INIT initiates a self-test in foreground mode, the HDD should be 
reserved.  If the HDD specifies the execution of a self-test in foreground mode, it 
will report the status when a pertinent command is issued after completion of the 
self-test. 

When a self-test in foreground mode is in process, the HDD will report "CHECK 
CONDITION" status (NOT READY [=2]/LOGICAL UNIT NOT READY, 
SELF-TEST IN PROGRESS [=04-09]) in response to any command other than 
the following: 

• 

INQUIRY command 

• 

REPORT LUNS command 

• 

REQUEST SENSE command 

If a test segment error occurs while the HDD is executing a self-test in foreground 
mode, the HDD will update a test result log page and report "CHECK 
CONDITION" status (HARDWARE ERROR [=04]/LOGICAL UNIT FAILED 
SELF-TEST [=3E-03]) 

The INIT can obtain additional information on the error by referencing the self-
test result log page. 

If the HDD fails to update the self-test result log page, it reports "CHECK 
CONDITION" status (HARDWARE ERROR [=4]/LOGICAL UNIT UNABLE 
TO UPDATE SELF-TEST LOG [=3E-04]). 

The INIT can terminate a foreground-mode self-test by issuing an abort request 
based on the ABORT TASK/ABORT TASK SET/CLEAR TASK SET function.  
Upon receiving an abort request, the HDD updates the self-test result log page and 
terminates the self-test in progress.
