2. Attempt to restart the system-management processor in the compute node. You can restart the
system-management processor through the CMM user interface. Click the compute node in the chassis
view and then click
Restart System Mgmt Processor . After the system-management processor has
been restarted, attempt to power off the compute node from the CMM.
3. Attempt to power off the compute node by using the power button on the front of the compute node.
4. Attempt to reset the compute node from the CMM command-line interface (CLI) by using the rrreset eset eset
command.
5. Reseat the CMM; then, perform steps 1-5 again.
Software problems
Complete the following steps until the problem is solved:
1. To determine whether the problem is caused by the software, make sure that:
• The compute node has the minimum memory that is needed to use the software. For memory
requirements, see the information that comes with the software.
Note: If you have just installed an adapter or memory, the compute node might have a
memory-address conflict.
• The software is designed to operate on the compute node.
• Other software works on the compute node.
• The software works on another compute node.
2. If you receive any error messages while you use the software, see the information that comes with the
software for a description of the messages and suggested solutions to the problem.
3. Contact your place of purchase of the software.
Undetermined problems
Use this information to solve undetermined problems.
Any undetermined problem
Complete the following steps until the problem is solved:
1. Check the IMM event log and follow the suggested actions to resolve any event codes (see “IMM
event log” on page 63).
2. Find the symptoms that you are experiencing in the troubleshooting tables in this section and follow
the suggested actions to solve any problems.
3. If the problem remains, submit a service request (see Appendix A “Getting help and technical
assistance” on page 687).
Compute nodes are not discovered by the Flex System Manager management node or the CMM
Complete the following steps until the problem is solved:
1. Make sure that the compute node is recognized by the Flex System Manager management node (if
installed) or the CMM. It might appear as an unknown device in the chassis map. If it is not recognized,
complete the following steps:
a. Remove the compute node and inspect the compute node and the back of the node bay to make
sure that there is no physical damage to connectors.
b. Move the compute node to another node bay.
c. Replace the system-board assembly (see “Removing the system-board assembly” on page 683 and
“Installing the system-board assembly” on page 684).
