Table 9-3. Advanced Settings Window Parameters
Parameter Description
Execution Throttle The maximum number of commands that can run on one
port. When the number of commands executing on a port
reaches the execution throttle value, no new commands can
be initiated until the current command finishes. This parame-
ter can be 1–65,535. The default is 65,535.
LUNs per Target The maximum number of LUNs per Fibre Channel port or
FCoE target device. Multiple LUN support is typically for RAID
servers that map drives with LUNs. The default is 128.
Enable Target Reset Enables or disables the adapter FCoE device drivers to issue
a Target Reset command to all devices on the loop when a
SCSI Bus Reset command is issued. The default is Yes.
Login Retry Count The number of times that the software will try to log in to a
device. The default is 8.
Port Down Retry Count The number of seconds that the software waits before resub-
mitting a command to a port that was down. The default is
30 seconds. When the QLogic adapter is connected to a stor-
age enclosure with a large number of drives, this parameter
can be increased. For recommended values, consult the stor-
age array product documentation.
Link Down Timeout The number of seconds that the software waits for a down link
to recover before reporting it to the upper layers. The default
is 30 seconds.
Operation Mode The reduced interrupt operation (RIO) mode, which enables
posting multiple command completions to the host in a single
interrupt. The default mode is 0. Operation Mode values are:
0—Interrupt for every command completion
5—Interrupt when the Interrupt Delay Timer expires
6—Interrupt when the Interrupt Delay Timer expires or
when there are no active commands.
Interrupt Delay Timer The number of 200-microsecond increments that the software
waits between accessing (DMA) a set of handles and gener-
ating an interrupt. This setting works in conjunction with the
Operation Mode parameter. The default is 0.
Enable Interrupt Enables or disables the use of the interrupt request queue
(IRQ) assigned to the adapter ASIC. When this parameter is
disabled, the BIOS polls for ISP mailbox command comple-
tion status. The default is No.
