Complete the following steps until the problem is solved.
- 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 IBM Flex System Chassis Management Module: Command-Line
Interface Reference Guide.
- 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.
- 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.
- 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.
- 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.
- Replace the system-board assembly (see Removing the base assembly and Installing the base assembly).
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 IBM Flex
System Manager user
interface.
