11.BootBIOS displays a menu of bootable devices. The devices are listed in boot order. The
primary boot device is the first device listed. If the primary boot device is unavailable, the
host boots from the next available device in the list. In the example shown in Figure 18-18,
only one LUN is available. This is because SAN zoning is configured to one path as
suggested in 18.2.1, "Configuration limits and preferred configurations" on page 221.
Select 01 to select the primary boot entry, and press Enter.

12.After the LUN is selected, another menu prompts you to specify how the boot device will
be identified. Generally, use the WWPN for all boot-from-SAN configurations. Select item
1 to boot this device using the WWPN as shown in Figure 18-19.
