13–Fibre Channel Over Ethernet
FCoE Boot from SAN
222 BC0054508-00 M
For OS installation over the FCoE path, you must instruct the Option ROM to
bypass FCoE and skip to CD or DVD installation media. As instructed in
“Preparing Marvell Multiple Boot Agent for FCoE Boot (CCM)” on page 214, the
boot order must be configured with Marvell boot first and installation media
second. Furthermore, during OS installation, it is necessary to bypass the FCoE
boot and pass through to the installation media for boot. To do so, perform
one-time disable of the FCoE boot ROM from booting, and not by simply allowing
the FCoE ROM to attempt to boot and allowing the BIOS to fail through and boot
the installation media. Finally, the FCoE ROM must successfully discover and test
the readiness of the boot LUN for installation to proceed successfully. Failure to
allow the boot ROM to discover the LUN and do a coordinated bypass will result in
a failure to properly install the OS to the LUN.
The two choices for the coordinated bypass include:
 When the FCoE boot ROM discovers a ready target LUN, it prompts you to
press the CTRL+D keys within four seconds to Stop booting from the
target. Press CTRL+D, and proceed to boot from the installation media.
 From CCM, set the Option ROM setting under MBA settings to One Time
Disabled. With this setting, the FCoE ROM loads and automatically
bypasses when the ready LUN is discovered. On the subsequent reboot
after installation, the option ROM will automatically revert to Enabled.
Wait through all option ROM banners. When FCoE Boot is invoked, it connects to
the target, and provides a four-second window to press the CTRL+D keys to
invoke the bypass, as shown in Figure 13-10. Press CTRL+D to proceed to
installation.
