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-devs command 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-children command 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-id command. Include the selected QLA2340/2340L HBA’s WWN,

loop ID, and LUN. For example:

ok 2200002037009eeb 82 0 set-boot-id

The following displays:

Calculating NVRAM checksum, please wait.... done

Boot device login successful

Boot WWN - 20000020 37009eeb WWPN - 22000020 37009eeb
