11 – Updating the HBA
Configuring an HBA’s Firmware Values
11-4 IS0054602-00 A
Q
In initiator mode, when this value is nonzero, the firmware limits the number
of outstanding commands to the smaller of this value and the number of
commands advertised by the target's MaxCmdSN value.
❑ Device Timeout. When this check box is selected, the QLA4xxx HBA
firmware ignores the IOCB command timeout values specified by the host.
❑ MaxBurstLength. This column indicates the maximum length for data
sequences the QLA4xxx HBA uses when negotiating with a device during
login phase. This parameter indicates how many units (512 bytes/unit) of
data the QLA4xxx HBA can send/receive. Valid values are in the range 0
to 32767 units (512 to 16 MB–1 bytes); a value of 0 indicates unlimited
data units.
❑ FirstBurstLength. This column indicates the maximum length for
unsolicited data the QLA4xxx HBA uses when negotiating with a device
during the login phase. This parameter indicates how many units
(512 bytes/unit) of unsolicited data the QLA4xxx HBA can send/receive.
Valid values are in the range 0 to 32767 units (512 to 16 MB–1 bytes); a
value of 0 indicates unlimited data units.
❑ RSVAddFWOpBinary. This field is used for debug and test purposes.
Contact QLogic for more information.
❑ Jumbo Packets Enable. When this check box is selected, jumbo packets
are enabled on an Ethernet network. This feature is not currently
supported.
❑ Delayed ACK. This parameter determines what occurs when the QLA4xxx
HBA receives a Data-In PDU with the Final bit set and no status reported.
When this check box is selected, the QLA4xxx HBA sends a TCP
acknowledgment immediately (this is the default value). When this check
box is not selected, the QLA4xxx HBA delays the acknowledgment and
waits for more data.
❑ Autoconnect. When this check box is selected, the QLA4xxx 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.
❑ MaxOutstanding R2T. This column indicates the maximum number of
outstanding R2Ts the QLA4xxx HBA uses when negotiating with a device
during the login phase. This parameter indicates how many R2Ts can be
outstanding on a SCSI task. Valid values are in the range 1–65535.
❑ Logout on Discovery Session. When this check box is selected, the
QLA4xxx HBA initiates an iSCSI logout on a discovery session when
discovery is complete (before closing the connection). When this check
box is cleared, the QLA4xxx HBA closes the TCP connection when
discovery is complete.
