Setting up boot LUN zoning
You must configure the server, HBA, and Brocade switch for boot LUN zoning to work. You must also know how to flash the HBA BIOS
or upload the latest version of Brocade Fabric OS (FOS) on a Brocade SAN switch or director. Note that Brocade FOS 6.2 or later and
HBA BIOS version 1.1 or later are required, and we recommend always using the latest BIOS and FOS version. Other than that, no
additional hardware or extra license or software is needed to deploy Fabric-Based Boot LUN Discovery. Use the FOS Command-Line
Interface (CLI) for configuration: neither Brocade DCFM nor Brocade Web Tools are required.
Configuring the server and HBA for BLUN zone
Brocade HBAs are factory-configured to support Fabric-based Boot LUN Discovery in the default BIOS setting. Verify that the BIOS is
enabled and that the Boot LUN is set to Auto Discover, as shown in the screen capture below.

Configuring the Brocade switch for BLUN zone
In addition to zoning and masking, you must configure an additional Boot LUN (BLUN) zone on the switch. At server boot, the Brocade
HBA (set to Auto Discover) makes a connection to the switch, retrieves the remote pWWN and the LUN from this BLUN zone, and tries
to boot from this LUN.
1. To configure a BLUN zone, use the bootLunCfg --add command.
