v
Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.

See Chapter 5, “Parts listing, Types 7917 and 2584,” on page 51 to determine which components are customer
replaceable units (CRU) and which components are field replaceable units (FRU) that must be replaced only
by a trained service technician.

If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
Single node does not power on
1. 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, the Chassis
Management Module event log.
2. 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 that
there is no physical damage to the connectors.
3. 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 user interface (click
Power Management > Power Modules and
Management ).
4. 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.
5. Replace the compute node.
Note: Until you are able to replace the compute node, you can attempt to
power on the compute node from the CMM or from the IBM Flex System
Manager user interface.
Multiple nodes do not power
on 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 Chassis
Management Module event log.
Compute node does not power
off
1. Attempt to power off the compute node through the IBM Flex System
Manager user interface, if an IBM Flex System Manager management node is
installed. 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.
3. Attempt to power off the compute node by using the power button on the
front of the node.
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.
