Solving shared BladeCenter resource problems
Problems with BladeCenter shared resources might appear to be in the blade
server, but might actually be a problem in a BladeCenter unit component.
This information provides procedures to help you isolate blade server problems
from shared BladeCenter resource problems.
If the problem is thought to be with a shared resource, see the online information
center or the
Problem Determination and Service Guide or the Hardware Maintenance
Manual and Troubleshooting Guide for your BladeCenter unit, or see the
documentation for BladeCenter unit components for additional information. If the
problem cannot be solved, see “Solving undetermined problems” on page 231.
To check the general function of shared BladeCenter resources, complete the
following operations.
1. Verify that the BladeCenter unit has the required power modules installed and
is connected to a working power source.
2. Verify that power management is set correctly for your BladeCenter unit
configuration.
3.
Verify whether the problem is being experienced on more than one blade
server.
4. Perform a test of the failing function on a blade server that is known to be
operational.
5. Try the blade server in a different blade bay.
6. Try a blade server that is known to be operational in the blade bay with the
failing blade server.
7. Verify that the blade server and the monitor are powered on.
8.
Check for keyboard problems, as described in “Solving shared keyboard
problems” on page 226.
9. Check for problems with the media tray (removable media drives and USB
ports), as described in “Solving shared media tray problems” on page 226.
10.
Check for network connection problems, as described in “Solving shared
network connection problems” on page 228.
11. Check for power problems, as described in “Solving shared power problems”
on page 229.
