Q
FW_Sense_Buffer_Desc
a
on, off When this parameter is on, the HBA
expects the last data segment descriptor
of the data descriptor list associated with
a Command Type 3 IOCB to be a
descriptor of a sense buffer.
When this parameter is off, the HBA
passes any sense data returned by the
target in a status IOCB.
FW_ZIO_Enable_Mode on, off When this parameter is on, the firmware
minimizes the number of interrupts it
generates to the host driver. Firmware
continues to post completions to the
queue without interrupting the driver for
each completion. When the ZIO count
threshold (ZIO parameter) is reached, the
host driver is interrupted. This interruption
notifies the host driver that there is
something in the queue that must be
drained. When an I/O completes before
the ZIO count threshold, the host driver is
interrupted, so that it can drain all the
completions for the I/Os.
AFW_Device_Timeouts on, off When this parameter is on, the HBA
firmware ignores the IOCB command
timeout values specified by the host.
AFW_Delayed_Ack on, off This parameter determines what occurs
when the HBA receives a Data-In PDU
with the Final bit set and no status
reported. When this parameter is on, the
HBA sends a TCP acknowledgment
immediately (this is the default value).
When this parameter is off, the HBA
delays the acknowledgment and waits for
more data.
AFW_AutoConnect on, off When this parameter is on, the HBA will
not attempt to autoconnect to the
configured target devices at boot time.
Instead, the host must issue Set Device
Database Entry commands (0063h) to
establish connections to targets.
