Symptom
Single node does not power on
Multiple nodes do not power
on
Compute node does not power
off
Single node does not power on
Complete the following steps until the problem is solved.
1. If you recently installed, moved, or serviced the computer node, reseat the compute node in the bay. If
the compute node was not recently installed, moved, or serviced, perform a virtual reseat through the
CMM service command. For more information about the CMM service command, see the

Action
1. Check the event logs for any events that are related to the compute node, and
solve them. If a management node is available, check the event log on the
management node. Otherwise, the Chassis Management Module event log.
2. Make sure that the CMM can recognize the compute node. Log in to the CMM
user interface and verify that the compute node appears in the chassis view. If
the CMM cannot recognize the compute node, 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 the connectors.
3. Make sure that the power policy that is implemented on the CMM is sufficient to
enable the compute node to power on. You can view the power policy from the
CMM user interface (click Power Management > Power Modules and
Management).
4. Make sure that the management node has completed the discovery of the
compute node. Log in to the management node user interface and verify that
the compute node appears in the list of manageable systems.
5. Replace the compute node.
Note: Until you are able to replace the compute node, you can attempt to
power on the compute node from the CMM or from the management node user
interface.
Check the event logs for any events that are related to the compute nodes, and
solve them. If a management node is available, check the event log on the
management node. Otherwise, check the Chassis Management Module event log.
1. Attempt to power off the compute node through the management node user
interface, if a management node is available. Otherwise, attempt to power off
the compute node through the CMM user interface.
2. Attempt to restart the system-management processor for 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 node.
4. Attempt to reset the compute node from the CMM command-line interface (CLI)
by using the reset command.
5. Reseat the CMM; then, perform steps 1-4 again.
