Compute nodes are not discovered by the IBM Flex System Manager management node or the CMM

Complete the following steps until the problem is solved.

1. Make sure that the compute node is recognized by the IBM® Flex System Manager management node (if installed) or the CMM. It may appear as an unknown device in the chassis map. If it is not recognized, perform the following steps.
   1. Remove the compute node and inspect both the compute node and the back of the compute node bay to ensure there is no physical damage to connectors.
   2. Move the compute node to another bay.
   3. Replace the system-board assembly (see Removing the system-board assembly and Installing the system-board assembly).
2. Make sure that the IBM Flex System Manager management node or the CMM can ping the compute nodes, if they cannot, see Cannot ping the IBM Flex System Manager management node on the management network.
3. If the compute nodes are in another chassis, make sure that you have the proper software entitlements to manage that chassis with the IBM Flex System Manager management node.
4. 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.
5. Check the IBM Support Portal for any service bulletins that are related to network connectivity.
