Configuring SAN Boot

You can configure SAN Boot on the Emulex FCoE BIOS configuration screen.

When you select a working mode, Personality must be set to FCoE.

To configure SAN Boot, perform the following steps:

1. Start the MZ510, and press Ctrl+E when the message shown in Figure 4-27 is displayed.

5. (Optional) Scan for a disk array.

   Select Scan for Target Devices, and press Enter. The screen for scanning for disk arrays is displayed, as shown in Figure 4-31. If the MZ510 is successfully connected to a disk array, the information about the disk array is displayed, as shown in Figure 4-32.

6. Configure the SAN Boot device.

   Select Configure Boot Devices, and press Enter. The screen for configuring boot devices is displayed.

11. Set the boot mode of a boot device to WWPN or DID. WWPN is the WWN of the interface on a target device (disk array), and DID is the N_Port_ID assigned to the interface on a target device (disk array) by the FC name server.
