■Execution Throttle. This setting specifies the maximum number of commands executing on any one port. When a port’s execution throttle is reached, no new commands are executed until the current command finishes executing. The valid options for this setting are 1–256. The default is 16.

■Fast Command Posting. This setting decreases command execution time by minimizing the number of interrupts. The default is Disabled.

■>4GByte Addressing. This option should be Enabled if the system has more than 4 GB of memory available. The default is Disabled.

■LUNs per Target. This setting specifies the number of LUNs per target. Multiple LUN support is typically for RAID boxes that use LUNs to map drives. The default is 8. If you do not need multiple LUN support, set the number of LUNs to 0.

■Enable LIP Reset. This setting determines the type of loop initialization process (LIP) reset that is used when the operating system initiates a bus reset routine. When this setting is Yes, the driver initiates a global LIP reset to clear the target device reservations. When this setting is No, the driver initiates a global LIP reset with full login. The default is No.

■Enable LIP Full Login. This setting instructs the ISP chip to re-login to all ports after any LIP. The default is Yes.

■Enable Target Reset. This setting enables the 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. This setting specifies the number of times the software tries to log in to a device. The default is 8 retries.

■Port Down Retry Count. This setting specifies the number of times the software retries a command to a port returning port down status. The default is 30 retries.

■Drivers Load RISC Code. When this setting is Enabled, the QLA2340/2340L HBA uses the RISC firmware that is embedded in the software driver. When this setting is Disabled, the software driver loads the RISC firmware that is stored in the QLA2340/2340L HBA BIOS. The default is Enabled.
