❑
Snack. When this check box is set and the firmware is configured as an
initiator, the QLA4010/4010C firmware sends SNACK requests to the
target when it detects missing PDUs. When this check box is cleared and
the firmware is configured as an initiator, the firmware aborts the command
and/or closes the connection when missing PDUs are detected.
❑
Initial R2T. When this check box is selected, the QLA4010/4010C HBA
negotiates (during login phase) for InitialR2T=yes. When this check box is
cleared, initial R2T is disabled and the QLA4010/4010C
HBA negotiates
for InitialR2T=no.
❑
Immediate Data. When this check box is selected, the QLA4010/4010C
firmware negotiates (during login phase) for Immediate Data=yes. When
this check box is cleared, immediate data is disabled and the firmware
negotiates for ImmediateData=no.
❑
Execution Throttle. This column specifies the execution throttle value.
The execution throttle is used by the QLA4010/4010C firmware to limit the
number of concurrently executing commands. Valid values are in the
range 0–65535.
In target mode, this column is used by the QLA4010/4010C to determine
the MaxCmdSN (maximum command sequence number) to report to an
initiator during a logged in iSCSI session.
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 QLA4010/4010C
firmware ignores the IOCB command timeout values specified by the host.
