Selecting The Boot Device; Fibre Channel Data Rates - Qlogic SANblade 2300 Series User Manual


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 2-6 lists 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-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
