The WWPN is 20:00: + <FIP MAC>. For example, if the FIP MAC is 00:10:18:11:22:33, then the WWPN will be
20:00:00:10:18:11:22:33.
NOTE: The default WWPN is 20:00: + <FIP MAC>. The default WWNN is 10:00: + <FIP MAC>.
NOTE: In Dell FlexAddress configurations, the SAN/FIP MAC may be overridden by the blade chassis management system.
CTRL+R Method
The CTRL+R method allows you to use the boot initiator to bring up the link and login into all available fabrics and targets.
Using this method, you can ensure that the initiator is logged into the fabric/target before making provisioning changes, and
as such, can provision without manually typing in WWPNs.
1. Configure at least one boot target through CCM as described above.
2. Allow the system to attempt to boot through the selected initiator.
3. Once the initiator boot starts, it will commence with DCBX sync, FIP Discovery, Fabric Login, Target Login, and LUN
readiness checks. As each of these phases completes, if the initiator is unable to proceed to the next phase, MBA will
present the option to press CTRL+R.
4. Once CTRL+R has been activated, the boot initiator will maintain a link in whatever phase has most recently succeeded
and allow you time to make the necessary provisioning corrections to proceed to the next phase.
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.
NOTE: This does not preclude the need to put the boot initiator into one-time disable mode as described in
Time Disable.
One-Time Disable
Broadcom'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 Broadcom 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 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 in order 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. In order 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 4 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 Disable. 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 Enable.
Wait through all option ROM banners. Once FCoE Boot is invoked, it will connect to the target, and provide a 4 second window
to press CTRL+D to invoke the bypass. Press CTRL+D to proceed to installation.
