If the installation or boot of ESXi from a software FCoE LUN fails, you can use several troubleshooting methods.


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.


  • Make sure that you correctly configured boot parameters in the option ROM of the FCoE network adapter.

  • During installation, monitor the BIOS of the FCoE network adapter for any errors.

  • If possible, check the VMkernel log for errors.

  • Use the esxcli command to verify whether the boot LUN is present.
