vSphere Storage n Coredump is not supported on any software FCoE LUNs, including the boot LUN. n Multipathing is not supported at pre-boot. n Boot LUN cannot be shared with other hosts even on shared storage. Best Practices for Software FCoE Boot VMware recommends several best practices when you boot your system from a software FCoE LUN. n Make sure that the host has access to the entire boot LUN. The boot LUN cannot be shared with other hosts even on shared storage. n If you use Intel 10 Gigabit Ethernet Controller (Niantec) with a Cisco switch, configure the switch port in the following way: n Enable the Spanning Tree Protocol (STP). n Turn off switchport trunk native vlan for the VLAN used for FCoE. Set Up Software FCoE Boot Your ESXi host can boot from a FCoE LUN using the software FCoE adapter a network adapter. When you configure your host for a software FCoE boot, you perform a number of tasks. Prerequisites The network adapter has the following capabilities: n Support partial FCoE offload (software FCoE). n Contain either a FCoE Boot Firmware Table (FBFT) or a FCoE Boot Parameter Table (FBPT). For information about network adapters that support software FCoE boot, see the vSphere Compatibility Guide. Procedure 1 Configure Software FCoE Boot Parameters on page 64 To support a software FCoE boot process, a network adapter on your host must have a specially configured FCoE boot firmware. When you configure the firmware, you enable the adapter for the software FCoE boot and specify the boot LUN parameters. 2 Install and Boot ESXi from Software FCoE LUN on page 65 When you set up your system to boot from a software FCoE LUN, you install the ESXi image to the target LUN. You can then boot your host from that LUN. Configure Software FCoE Boot Parameters To support a software FCoE boot process, a network adapter on your host must have a specially configured FCoE boot firmware. When you configure the firmware, you enable the adapter for the software FCoE boot and specify the boot LUN parameters. Procedure u In the option ROM of the network adapter, specify software FCoE boot parameters. These parameters include boot target, boot LUN, VLAN ID, and so on. Because configuring the network adapter is vendor specific, review your vendor documentation for instructions. 64 VMware, Inc.
Install and Boot ESXi from Software FCoE LUN When you set up your system to boot from a software FCoE LUN, you install the ESXi image to the target LUN. You can then boot your host from that LUN. 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. n Use the esxcli command to verify whether the boot LUN is present. esxcli conn_options hardware bootdevice list Chapter 8 Booting ESXi with Software FCoE VMware, Inc. 65
