Chapter 7 Booting ESXi from Fibre Channel SAN2 Configure the storage array.abcdefFrom the SAN storage array, make the ESXi host visible to the SAN. This process is often referredto as creating an object.From the SAN storage array, set up the host to have the WWPNs of the host’s adapters as portnames or node names.Create LUNs.Assign LUNs.Record the IP addresses of the switches and storage arrays.Record the WWPN for each SP.CAUTION If you use scripted installation to install ESXi in boot from SAN mode, you need to takespecial steps to avoid unintended data loss.Configure Storage Adapter to Boot from SANWhen you set up your host to boot from SAN, you enable the boot adapter in the host BIOS. You thenconfigure the boot adapter to initiate a primitive connection to the target boot LUN.PrerequisitesDetermine the WWPN for the storage adapter.ProcedureuConfigure the storage adapter to boot from SAN.Because configuring boot adapters is vendor specific, refer to your vendor documentation.Set Up Your System to Boot from Installation MediaWhen setting up your host to boot from SAN, you first boot the host from the VMware installation media.To achieve this, you need to change the system boot sequence in the BIOS setup.Because changing the boot sequence in the BIOS is vendor specific, refer to vendor documentation forinstructions. The following procedure explains how to change the boot sequence on an IBM host.Procedure1 During your system power up, enter the system BIOS Configuration/Setup Utility.2 Select Startup Options and press Enter.3 Select Startup Sequence Options and press Enter.4 Change the First Startup Device to [CD-ROM].You can now install ESXi.VMware, Inc. 57
