Figure 87. Vendor Unique Parameters - Page 0
Parameters in [] such as [CPE] are ignored. Ignored parameters can take any value. Reserved (RSVD)
parameters should be set to zero.
Fields marked in the table as 'Ignored' are not used or checked by the drive. They will be initialized to zero
but may be set as desired for compatibility with older drives.
!
QPE (Qualify Post Error) of one causes the drive to report only those recovered data errors which
exceed the QPE Read/Write Threshold. If QPE is set to one, IRT and IVR should be set to zero. QPE
of zero causes the drive to report all recovered data errors.
!
SSM (Synchronous Select Mode) of one enables the drive to initiate an SDTR message and a WDTR
message the first time a LUN is selected with Attention and is in asynchronous mode or narrow mode
if Enable TI-SDTR jumper is not installed. If Enable TI-SDTR jumper is installed, this bit is ignored.
!
UAI (Unit Attention Inhibit) is ignored when the UAI jumper is removed from the drive. If the UAI
jumper is added to the drive, then this bit controls the generation of unit attention conditions.
!
MRG (Merge G-List into P-List) of one enables the merging the Grown Defect List (G-List) entries into
the Primary Defect List (P-List) during FORMAT UNIT command.
!
ARHES (Automatic Reassign Hard Error Sites) of one causes the LBA of a unrecovered read error
internally registered as a reassign candidate and, when a WRITE command is received to the failing
LBA, the data is written and verified if the error still exists. If the error still occurs on the failing LBA, it
will be reassigned. If the error is cleared, the drive will remove the reassign candidate for the LBA.
