Setting up the NVRAM and BIOS with the Emulex HBA
This section describes setting up the NVRAM and BIOS with the Emulex HBA.
Configure the following NVRAM settings using the Emulex Lightpulse BIOS utility. Access the BIOS
utility by hard booting the server and, when prompted, perform the procedures in this section.
NOTE: The NVRAM settings on Emulex HBAs can be changed by any server in which they are
installed. These settings will persist for an HBA even after it is removed from a server.
Enabling an Adapter to Boot from SAN
1. To start the BIOS utility, turn on the computer, hold down the Alt or Ctrl key, and press E within
five seconds to display the bootup message.
The adapter listing is displayed.
NOTE: Each HBA port is reported as a host bus adapter. The following settings need to be
applied for each HBA port.
2. Select a host adapter from the main menu.
3. From the Main configuration menu, select Enable/Disable Boot from SAN.
Adapters are disabled by default. At least one adapter must be enabled to boot from SAN
in order to use remote boot functionality.
Configuring Boot Devices
NOTE: If it is necessary to change the topology, do so before you configure the boot devices.
The default topology is auto topology with loop first.
1. On the main configuration menu select Configure Boot Devices.
A list of eight boot devices is shown.
2. Select a boot entry.
3. Select <00> to clear the selected boot entry, or select a device to configure booting by.
4. If you select a device, enter the starting LUN. The starting LUN can be any number from 0 to
255.
NOTE: You can define 256 LUNs per adapter, but the screen displays only 16 consecutive
LUNs at a time. In front of each entry, B#D or B#W specifies the boot entry number and
whether the device boots by DID or WWPN. For example, B1D means that boot entry 1 boots
from the DID. B2W means that boot entry 2 boots from WWPN.
5. Type the two digits corresponding to the entry you are selecting.
6. Select the boot method you want. If you select to boot the device by WWPN, the WWPN of
the earlier selected entry is saved in the flash memory. If you select to boot this device by DID,
the earlier selected entry is saved in the flash memory.
7. Press the Esc key until you exit the BIOS utility.
8. Reboot the system for the new boot path to take effect.
Refer to the Emulex Boot Code User Manual for more detail and additional options.
Configuring the Emulex HBA using the HBACMD Utility
This section describes how to configure the Emulex HBA using the HBACMD utility.
Emulex provides a CLI utility (OneCommand) to configure their HBAs. This is also available as a
GUI. These tools, once installed, can be used to configure many HBA and driver parameters.
