This chapter provides basic troubleshooting information to help you solve some
common problems that might occur while setting up your blade server.
A problem with the BladeCenter BladeCenter QS20 can relate to either the
BladeCenter BladeCenter QS20 or the BladeCenter unit.
v A blade-server problem exists if the BladeCenter unit contains more than one
blade server and only one of the blade servers has the symptom.
v
If all of the blade servers have the same symptom, then the problem relates to
the BladeCenter unit. For more information, see the IBM BladeCenter (Type
8677) Hardware Maintenance Manual and Troubleshooting Guide .
If you install the blade server in the BladeCenter unit and the blade server does not
start, perform the following actions:
v
Make sure that the BladeCenter unit is correctly connected to a power source.
v Reseat the blade server in the BladeCenter unit ( see Chapter 4, “ Installing the
blade server in the BladeCenter unit, ” on page 1 7 ) .
v
If the power-on L E D is flashing slowly, turn on the blade server ( see “ Turning on
the blade server ” on page 9) .
v If you have j ust added a new optional device or component, make sure that it is
correctly installed and compatible with the blade server and its components. If
the device or component is not compatible, remove it from the blade server,
reinstall the blade server in the BladeCenter unit, and then restart the blade
server.
If the blade server does not start after you have performed the preceding actions,
see the Problem Determination and Service Guide for your blade server on the
Documentation CD.
F irmware startup process
The firmware displays the progress of the startup process on the serial console
from the time that ac power is connected to the system until the operating-system
login prompt is displayed after a successful operating-system startup.
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 xxxx represents the number of the error code:
Cxxxx This is an internal checkpoint. If the system hangs during the
startup process and displays this type of error, contact a service
support representative.
Exxxx This type of error means that there is a failure that does not allow
the firmware to continue the startup process. Contact a service
support representative.
Descriptions of each of the error codes for Cxxxx, and E xxxx are not included in
this document, see the Problem Determination and Service Guide for your blade
server.
