d. If the system has been in a firmware "Pending" state, allow the system to go through
multiple reboot cycles to update the CRTM. This can take upwards of 30 minutes. The
F1 prompt displays when the system reboot is complete.
e. Load the defaults, save, and exit. The system goes down to reboot.
f. Remove the AC power, remove the primary IO book, and re-install the adapters.
g. Insert the Storage Book.
h. Reapply power and log into the IMM to power on the system. The system comes up to
the F1 prompt.
i. Load the defaults, save, and exit. The system goes down to reboot. When the system
goes down, remove the AC power.
j. Insert the remainder of the CPU books and IO Modules.
k. Reapply power and log into the IMM to power on the system. The system comes up to
the F1 prompt.
l. Load the defaults, save, and exit. The system goes down to reboot. Allow the system to
successfully complete a power recalibration cycle. When the system successfully
comes up to the F1 prompt, use the IMM or front power button to turn off the system
power.
m. Remove AC power and reinstall the remainder of the option cards.
n. Allow the system to boot to F1, load the defaults, save, and reboot.
Before adding CPU books, power off the server and remove the AC power cords. If you did
not remove the AC power when adding a CPU book and if the server fails to restart
properly (either fails to power on or goes into an endless boot loop), the IMM data might
have corrupted. The solution is to reflash both IMM banks again.
Quick method: Re-flashing the IMM can take up to 15 minutes, but you can still ping
the IMM and log in via SSH. You can use a quick "hack" method to update it. Download
and extract the UXSPI tool, grab the "iflash" directory and your .uxz file, and run the
following command to iflash it remotely out of band:
iflash64.exe --package IMMfirmwarefile.uxz --host XXX.XXX.XXX.XXX --user
USERID --password PASSWORD --unattended [--reboot ]
Make sure fillers are installed in the empty drive cages and backplanes or the system will
generate thermal alerts.
Windows 2012 R2 Installations have issues in Legacy mode. This is due to the inclusion of
the Secure Boot functionality in the system. To install Windows 2012, you must use UEFI
mode. Legacy mode installation fails with a "winload.exe" error prior to the graphical part
of the install commencing.
If the remote install SLES 11 does not boot the ISO file using the virtual, the workaround is
to:
a. Log in to the IMM and start the virtual media.
b. Mount the SLES 11 ISO file.
c. Apply power to the x3850 X6 and boot to setup using F1.
d. Select Boot Manager  Boot from File. The USB CDROM device, which is the virtual
media device, is displayed.
e. Select the device and press Enter.
f. Select EFI and press Enter.
