IBM QS22 - BladeCenter - 0793, Installation And User Manual

Page: 83 / 114

If a serial console is not connected, you can use the Advanced Management
Module to monitor the logs and display informational and error messages.
If the firmware encounters an error during the startup process, a message
describing the error together with an error code is displayed on the serial console.
There are two types of error, where xxx represents the number of the error code:
Cxxx This is an internal checkpoint. If the system stops during the startup
process a checkpoint may be displayed.
Exxx This type of error means that there is a failure that does not allow
the firmware to continue the startup process. Check the error codes
in the QS22 Problem Determination and Service Guide . If these do
not help resolve the problem, contact a service support
representative.
There are cases where a message that is informational only is displayed on the
serial console.
Wxxx This is a warning message. The firmware allows the startup process
to continue, but indicates there maybe a problem. A warning
message can be combined with an error message to give more
complete information about an error.
Descriptions for each of the error codes are not included in this document. See the
Problem Determination and Service Guide for your blade server for further
information.
Checkpoints
Checkpoints show the progress of the boot. Each checkpoint is overwritten by the
next as the boot process continues. If the boot process stops for any reason, a
checkpoint may be displayed. Take note of the checkpoint code and any message,
then attempt to reboot the blade server.
If the problem persists, contact your IBM service representative with details of the
checkpoint and any message associated with it.
