2. Check the event logs for any events that are related to the compute node, and solve them. If an
Flex System Manager management node is installed, check the Flex System Management event log
. Otherwise, check the Chassis Management Module event log.
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 "Flex 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_
pmpolicy.html.
• From the CMM web interface, select Power Modules and Management
from the Chassis Management menu. For more information, see the
the "Flex System Chassis Management Module: User's Guide" at
http://pic.dhe.ibm.com/infocenter/flexsys/information/topic/com.lenovo.acc.cmm.doc/ cmm_user_
guide.html. All fields and options are described in the CMM web interface online help.
5. Make sure that the Flex System Manager management node has completed the discovery of the
compute node. Log in to the Flex System Manager user interface and verify that the compute node
appears in the chassis view from the CMM.
6. Replace the system-board assembly (see “Removing the system-board assembly” on page 683 and
“Installing the system-board assembly” on page 684).
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 Flex System Manager user interface.
For additional information, see UEFI Compliant Firmware on System x® and BladeCenter® Servers and the
Flex 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 "Flex 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 an Flex
System Manager management node is installed, check the Flex System Manager event log Otherwise,
check the Chassis Management Module event log.
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 Flex System Manager user interface, if an Flex
System Manager management node is installed. Otherwise, attempt to power off the compute node
through the CMM user interface.
