Single node cannot ping the management node in the same chassis
Use the information in this section to troubleshoot a single compute node that cannot ping the IBM Flex
System Manager management node in the same chassis on the management network.
1. Make sure that the management node is powered on and is not hung, by logging in to the management
node. If you are unable to log in from the management network, attempt to log in from the data network.
If the management node is powered on and hung, perform a virtual reseat of the management node
from the Chassis Management Module (CMM).
2. Make sure that the Chassis Management Module (CMM) is powered on and is not hung, by pinging the
Chassis Management Module (CMM) from the management node. If the Chassis Management Module
(CMM) is powered on and hung, reset the Chassis Management Module (CMM). Make sure that the
IMM, the management node, and Chassis Management Module (CMM) are all on the same subnet.
3. Make sure that the compute node is the only one in the chassis that the management node cannot
ping. If it is not, follow the steps in Multiple nodes cannot ping the management node in the same
chassis. Make sure that the compute node appears on the chassis map (it might not be fully discovered
by the management node software).
4. Make sure that the system-management processor in each compute node has a valid IP address by
checking the chassis map of the remote chassis.
5. Note: If the Chassis Management Module (CMM) recently lost connection to the DCHP server, you must
reset the IMM by using the Chassis Management Module (CMM) interface so that a new IP address
can be acquired.
6. In the Chassis Management Module (CMM) user interface, click Chassis Management > Component
IP Configuration and make sure that the IP address that is listed is the same as the IP address that is
displayed in the Setup utility. If it is not the same, configure the IMM network settings correctly.
7. Check the IBM Support Portal for any firmware updates that might apply to this issue. You can view the
release notes for a firmware update to determine the issues that are addressed by the update.
8. Check the IBM Support Portal for any service bulletins that are related to network connectivity.
9. Remove the compute node and make sure that the connectors on the midplane and the node are not
damaged.
10. (Trained service technician only) Complete the following steps:
a. Force the link/duplex speed.
b. Check the connectors on the node and the midplane to make sure that no pins are bent.
c. Replace the system-board assembly (see Removing the system-board assembly and Installing
the system-board assembly).
