Prerequisites n Configure the option ROM of the network adapter to point to a target LUN that you want to use as the boot LUN. Make sure that you have information about the bootable LUN. n Change the boot order in the system BIOS to the following sequence: a The network adapter that you use for the software FCoE boot. b The ESXi installation media. See the vendor documentation for your system. Procedure 1 Start an interactive installation from the ESXi installation CD/DVD. The ESXi installer verifies that FCoE boot is enabled in the BIOS and, if needed, creates a standard virtual switch for the FCoE capable network adapter. The name of the vSwitch is VMware_FCoE_vSwitch. The installer then uses preconfigured FCoE boot parameters to discover and display all available FCoE LUNs. 2 On the Select a Disk screen, select the software FCoE LUN that you specified in the boot parameter setting. If the boot LUN does not appear in this menu, make sure that you correctly configured boot parameters in the option ROM of the network adapter. 3 Follow the prompts to complete the installation. 4 Reboot the host. 5 Change the boot order in the system BIOS so that the FCoE boot LUN is the first bootable device. ESXi continues booting from the software FCoE LUN until it is ready to be used. What to do next If needed, you can rename and modify the VMware_FCoE_vSwitch that the installer automatically created. Make sure that the Cisco Discovery Protocol (CDP) mode is set to Listen or Both. Troubleshooting Installation and Boot from Software FCoE If the installation or boot of ESXi from a software FCoE LUN fails, you can use several troubleshooting methods. Problem When you install or boot ESXi from FCoE storage using a VMware software FCoE adapter and a network adapter with partial FCoE offload capabilities, the installation or the boot process fails. Solution n Make sure that you correctly configured boot parameters in the option ROM of the FCoE network adapter. n During installation, monitor the BIOS of the FCoE network adapter for any errors. n If possible, check the VMkernel log for errors.

Best Practices for Fibre Channel Storage 9 When using ESXi with Fibre Channel SAN, follow best practices that VMware offers to avoid performance problems. The vSphere Web Client offer extensive facilities for collecting performance information. The information is graphically displayed and frequently updated. You can also use the resxtop or esxtop command-line utilities. The utilities provide a detailed look at how ESXi uses resources in real time. For more information, see the vSphere Resource Management documentation.
