FRU SVCPROC-replace SP
The service processor is failing. After you have replaced the part, set the configuration ID for
SPCN before powering up, otherwise the machine will not IPL.
You can change the processing unit identifier, also referred to as the processing unit SPCN
(system power control network) ID. The processing unit SPCN ID is used by the SPCN
firmware to identify the system type. It is also used to identify the primary service processor if
there are two service processors in the system.
To perform this operation, your authority level must be one of the following:
򐂰 Administrator
򐂰 Authorized service provider
To change the processing unit identifier, do the following operations:
򐂰 On the ASMI Welcome pane, specify your user ID and password, and click Log In.
򐂰 In the navigation area, expand System Configuration.
򐂰 Select Processing Unit Identifier.
򐂰 Enter the desired information into the 2-character text area. Then click OK.
6.10 HMC boot up fails with “fsck”
There are certain circumstances where the HMC can fail and leave the file subsystem corrupt
or damaged. Power failure is the most common form of incident, caused by inadvertently
hitting the white power button, pulling the power cable, or power supply failure.
The HMC has the ability to recover itself in most incidents. Consider a failure when the HMC
was performing a normal shutdown. During boot up, the HMC could stop with the following
message displayed in the HMC windows:
'fsck failed please repair manually. login with root
In this case, root is the operating system Root password. If you have not completed the
Guided Setup, the default password will still be active, the default password is ‘passw0rd’
and is case sensitive. If you have completed the Guided Setup, you will have changed the
default root password. You should use this new password.
Once you have logged in with root password, you will be presented with a command prompt.
At the prompt type in ‘fsck’ and press Enter. You will see the fsck process running in line
mode. You will be asked if the OS should repair certain components. You should say yes to
all prompts unless you are instructed otherwise. Once fsck completes, you may automatically
return to the GUI signon screen. If you are not returned to the GUI, you should type ‘reboot’
at the prompt and press Enter. The HMC GUI signon screen will appear.
When you sign onto the HMC and the management pane appears, you may have to
reconnect or find the managed server if it does not automatically appear.
