Use the set-data-rate command to change the current QLA2340/2340L Fibre Channel data rate. For example:

ok 1 set-data-rate

Calculating NVRAM checksum, please wait...

Current HBA data rate: Two Gigabit rate

Table 2-6lists the values to enter and their corresponding data rates. QLogic recommends the Auto-negotiated rate (2), which works for most devices.

Selecting the Boot Device

Perform the following steps to select a Fibre Channel device that is attached to the QLA2340/2340L HBA as the boot device:

1.Use the show-devscommand to display the device tree for all devices attached to the machine.

ok show-devs

The device tree displays. The QLA2340/2340L HBAs with FCode are referenced with QLGC,qla@. For example:

ok show-devs

.

.

/pci@1f,0/pci@1/QLGC,qla@4

2.Select the QLA2340/2340L HBA attached to the Fibre Channel device from which you want to boot. For example, type the following at the ok prompt:

ok " /pci@1f,0/pci@1/QLGC,qla@4" select-dev

3.Use the show-childrencommand to view the devices attached to the QLA2340/2340L HBA. For example:

ok show-children

4.The list of devices displays. Write down the boot device’s world wide name (WWN), loop ID, and logical unit number (LUN).

5.Save the boot device information to the QLA2340/2340L HBA’s NVRAM. Use the set-boot-idcommand. Include the selected QLA2340/2340L HBA’s WWN, loop ID, and LUN. For example:

ok 2200002037009eeb 82 0 set-boot-id
