4 Fabric-based boot LUN discovery NOTE Fabric-based boot LUN discovery is not supported for booting from direct-attached targets. Configuring fabric-based boot LUN discovery (Brocade fabrics) For Brocade fabrics, the following methods are available to store the boot LUN information in the fabric zone database: • Using the Fabric OS bootluncfg command to transparently configure the boot LUN. • Using the BCU boot --blunZone command to provide the zone name and zone members to use as operands in the Fabric OS zoneCreate command. Using Fabric OS bootluncfg command Fabric-based boot LUN discovery allows the host's boot LUN information to be stored in the fabric zone database by using a zone name that contains the PWWN of an HBA port. The zone members consist of storage target PWWN and LUN ID. The bootluncfg command provides a simplified and transparent procedure for configuring the boot LUN. Once configured, the HBA boot code queries the zone member list for the zone name matching the HBA PWWN to determine the boot target and LUN. For details on this command and additional parameters, refer to the Fabric OS Command Reference Guide. Using BCU boot --blunZone command Use the Fabric OS zoneCreate command to create a zone on the switch where the adapter is connected. zonecreate "zonename", "member[; member...]" • The "zonename" operand will be "BFA_[adapter port WWN]_BLUN." For example, if the adapter PWWN is 01:00:05:1E:01:02:03:04, the zone name will be the following. BFA_0100051E01020304_BLUN • The zone "member" operands must be specially coded values for the target PWWN and LUN identification (for example, 06:00:00:02:DD:EE:FF:00). To obtain the zoneCreate operand values, you will run the BCU boot --blunZone command from your host system's command line. Use the following steps to configure fabric-based boot LUN discovery. 1. Set the adapter's BIOS configuration to fabric discovered using one of the following interfaces: • Brocade BIOS Configuration Utility Adapter Settings > Boot LUN > Fabric Discovered • HCM Basic Port Configuration > Boot-over-SAN > Fabric Discovered • BCU bios --enable -o auto 2. Enter the following BCU command to provide the zone name and zone members to use as operands in the Fabric OS zoneCreate command. 164 Brocade Adapters Installation and Reference Manual 53-1002144-01
