When 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 for instructions. The following procedure explains how to change the boot sequence on an IBM host.


During your system power up, enter the system BIOS Configuration/Setup Utility.


Select Startup Options and press Enter.


Select Startup Sequence Options and press Enter.


Change the First Startup Device to [CD-ROM].

You can now install ESXi.
