Multiple nodes cannot ping the management node in the same chassis

Use the information in this section to troubleshoot multiple nodes that cannot ping the Flex System Manager management node in the same chassis on the data network.

Action​

Complete the following steps until the problem is solved:
  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 CMM.
  2. Make sure that the I/O module is powered on and is not hung, by pinging the I/O module from the management node. If the I/O module is powered on and hung, reset the I/O module. Make sure that the correct ports are enabled for the node on the I/O module.
  3. Make sure that the management network port (eth1) is enabled in the management node. Make sure that the port configuration settings are correct for the data network.
  4. Make sure that the configuration settings for each node are correct and that the data network ports are enabled.
  5. Make sure that the configuration settings in the I/O module are correct and that the applicable ports are enabled for your compute nodes and the management node on the I/O module. If the problem remains, complete the following steps:
    1. Restart the I/O module.
    2. Check the Lenovo 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.
    3. Perform a virtual reseat of the I/O module.
    4. Replace the I/O module.
  6. Check the Lenovo Support Portal for any service bulletins that are related to network connectivity.
  7. Remove the management node and make sure that the connectors on the chassis midplane and the management node are not damaged.
  8. (Trained service technician only) Complete the following steps:
    1. Force the link/duplex speed.
    2. Check the connectors on the nodes and the chassis midplane to make sure that no pins are bent.
    3. Replace the I/O expansion card in the management node.
    4. Replace the system-board assembly in the management node.
