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.
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 "IBM Flex
System Chassis Management Module: Command-Line Interface Reference Guide".
2. Check the event logs for any events that are related to the compute nodes, and solve them. If an IBM
Flex System Manager management node is installed, check the event log on the management node.
Otherwise, check the event log on the Chassis Management Module.
Single Node does not power on.
Complete the following steps until the problem is solved.
1. If you recently installed, moved, upgraded, 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
"IBM Flex System Chassis Management Module: Command-Line Interface Reference Guide".
2. Check the event logs for any events that are related to the compute node, and solve them. If an IBM
Flex System Manager management node is installed, 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.
a. For more information about the CMM pmpolicy command, see the "IBM Flex System Chassis
Management Module: Command-Line Interface Reference Guide".
b. From the CMM web interface, select Power Modules and Management from the Chassis
Management menu. For more information, see the "IBM Flex System Chassis Management Module:
User's Guide". All fields and options are described in the CMM web interface online help.
5. Make sure that the IBM Flex System Manager management node has completed the discovery of the
compute node. Log in to the IBM 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 and Installing the
system-board assembly).
