Use this information to solve compute node discovery problems.
- 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:
- 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.
- Move the compute node to another bay.
- Replace the system-board assembly (see Removing the system-board
assembly and Installing the system-board assembly).
- 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.
- 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.
- 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.
- Check the IBM Support Portal for any service bulletins that are
related to network connectivity.
