QPE (Qualify Post Error) bit allows the Initiator to inhibit the reporting of recovered data errors which
are recovered under Data Recovery Procedure (DRP) step. A QP E bit of zero causes the Target to
report all recovered data errors. A Q P E bit of one causes the Target to report only those recovered data
errors which exceed the Q PE threshold.
UQE (Untagged Queuing Enable) bit controls whether or not untagged queuing is allowed.
UAI (Unit Attention Inhibit) bit is not used during normal operation while the UAI jumper is removed
from the drive. It may however be changed by the user with no effects. 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) bit is set to 1 to merge the Grown Defect List (G-List) entries into the
|
Primary Defect List (P-List) when Format Unit command is executed.
SCAM level, SCAM level control bits, specify the SCAM function level to be supported.
DADM, Disable Automatic Drive Maintenance bit, is set to zero to indicate that the A D M function is
enabled to maintain M T T F of the drive. The D A D M bit of one disables the A D M function.
CMDAC (Command Active) bit determines in conjunction with LED Mode bits if an L E D on the file is
activated while commands are active. If C M D A C bit is one and L E D bits are zero, an L E D driver is
active when a command is queued or executed.
CPE (Concurrent Processing Enable) bit is allowed to be modified by the initiator for host system device
driver compatibility. Read(6), Read extend(10), Write(6), Write extend(10), untagged and unlinked
Request Sense or Inquiry can be executed concurrently in both CPE bit set to 0 and 1.
