Complete the following steps until the problem is solved.
- 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".
- 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.
- For more information about the CMM pmpolicy command, see the "IBM
Flex System Chassis Management Module: Command-Line Interface Reference
Guide".
- 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.
- 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 system-board
assembly and Installing the system-board assembly).
