9. If you are also installing a new system board, you must complete this
procedure before installing the new system board:
a.
Shut down the operating system, turn off the blade server, and remove the
blade server from the BladeCenter unit. See “Removing the blade server
from a BladeCenter unit” on page 241.
b. Perform the procedure for replacing the system board to install the new
system board. See “Replacing the Tier 2 system-board and chassis
assembly” on page 274.
Entering vital product data
The management card contains the vital product data (VPD) for the service
processor.
IBM sets the correct VPD values for a new JS12 blade server. If you order a
replacement management card, the replacement part is not configured. If you
install the management card on the original system board and chassis assembly,
the firmware recognizes the new management card during the initial program load
(IPL) and uses cached values to initialize the management card correctly. After the
management card is initialized, nothing can change its data values.
If you also replace the system board and chassis assembly, or if you somehow
delete the cached data from NVRAM, the firmware cannot initialize the new
management card. At that time, the firmware prompts you for values for the vital
product data.
You cannot boot the blade server until you enter valid values for the data.
Important: The first time that you turn on the blade server after you replace the
system board and chassis assembly and the management card, the firmware
prompts you to enter the product type and model and other vital product data
(VPD). If you enter the wrong values, you cannot correct them after the firmware
initializes the management card. Wrong values can prevent the JS12 blade server
from booting.
Refer to the VPD information that you recorded when you installed the JS12 blade
server, as described in the introduction of the
Installation and User’s Guide . To
determine the values for your JS12 blade server, use the management module and
the
lsvpd
command. If you are running Linux, download and install the service
and productivity tools for Linux on POWER systems to install the lsvpd command.
The following table includes a place for you to record the JS12 vital product data.
If you must replace the system board and chassis assembly, you will need the
information.
