2. 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, check the
event log on the Chassis Management Module.
3. 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
there is no physical damage to the connectors.
4. 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 pmpolicy command and the CMM
web interface.
• For more information about the CMM pmpolicy command, see the

information/topic/com.lenovo.acc.cmm.doc/cli_command_ pmpolicy.html
• From the CMM web interface, select Power Modules and Management from the Chassis
Management menu. For more information, see the
User's Guide" at http://pic.dhe.ibm.com/infocenter/flexsys/information/topic/com.lenovo.acc.cmm.doc/

5. 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.
6. Replace the base assembly (see
Note: Until you are able to replace the system-board assembly, you can attempt to power on the
compute node from the CMM or from the management node user interface.
For additional information, see
System Quick start guides
Multiple nodes do not power on
Complete the following steps until the problem is solved.
1. If you recently installed, moved, or serviced the computer nodes, reseat the compute nodes in the bays.
If the compute nodes were 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
System Chassis Management Module: Command-Line Interface Reference Guide" at http://pic.dhe.ibm.com/
infocenter/flexsys/information/topic/com.lenovo.acc.cmm.doc/cli_command_ service.html
2. 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
event log on the Chassis Management Module.
Compute node does not power off
Complete the following steps until the problem is solved.
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.
