Selecting the Boot Device

Perform the following steps to select a Fibre Channel device that is attached to the QCP2340/2342 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 QCP2340/2342 HBAs with FCode are referenced with QLGC,qla@. For example:

ok show-devs

.

.

/pci@1f,0/pci@1/QLGC,qla@4 (QCP2340, QCP2342 first channel) /pci@1f,0/pci@1/QLGC,qla@4,1 (QCP2342, second channel)

2.Select the QCP2340/2342 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 QCP2340/2342 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 QCP2340/2342 HBA’s NVRAM. Use the set-boot-idcommand. Include the selected QCP2340/2342 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 Id - 82 Lun - 0

ok

6.To boot the QCP2340/2342 HBA, type the complete boot path, including the loop ID and LUN. The loop ID and LUN must match those entered in step 5. For example:

ok boot /pci@1f,0/pci@1/QLGC,qla@4/sd@82,0

NOTE: Enter the reset command before attempting to boot if the boot was interrupted or any of the QLogic FCode commands were executed.
