5.
If the initiator logs into the fabric, but is unable to log into the target, a
CTRL+R will pause the boot process and allow you to configure fabric
zoning.
6.
Once zoning is complete, the initiator will automatically log into all visible
targets. If the initiator is unable to discover the designated LUN on the
designated target as provisioned in step 1, CTRL+R will pause the boot
process and allow you to configure selective LUN presentation.
7.
The boot initiator will periodically poll the LUN for readiness, and once the
user has provisioned access to the LUN, the boot process will automatically
proceed.
One-Time Disabled
QLogic's FCoE ROM is implemented as Boot Entry Vector (BEV). In this
implementation, the Option ROM only connects to the target once it has been
selected by BIOS as the chosen boot device. This is different from other
implementations that will connect to the boot device even if another device has
been selected by the system BIOS. For OS installation over the FCoE path, it is
necessary to instruct the Option ROM to bypass FCoE and skip to CD/DVD
installation media. As instructed earlier, the boot order must be configured with
QLogic boot first and installation media second. Furthermore, during OS
installation, it is required to bypass the FCoE boot and pass through to the
installation media for boot. It is required to do this by one-time disabling 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,
it is required that the FCoE ROM successfully discover and test the readiness of
the desired 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 O/S to the LUN. To affect this coordinated bypass, there are
two choices:
Once the FCoE boot ROM discovers a ready target LUN, it will prompt you
to press CTRL+D 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 will load once and automatically
bypass once the ready LUN is discovered. On the subsequent reboot after
installation, the option ROM will automatically revert to
Enabled
.
NOTE
This does not preclude the need to put the boot initiator into one-time
disabled mode as described in
