Sudden connectivity loss to a resource manager

Use this information to troubleshoot issues when a resource manager or device goes offline.

  • For Lenovo XClarity Administrator resource managers, ensure that the event forwarder in the XClarity Administrator management server is enabled. XClarity Orchestrator creates and enables an event forwarder in the XClarity Administrator management server when a connection is created to that resource manager.
  • Check the event log for any network events for the resource manager, and resolve those first. For more information about the event log, see Monitoring events.
  • Attempt to log in directly to the resource manager, and ensure that the credentials have not changed.
  • Ensure that the IP address for the resource manager is valid for the network. Ping the IP address to test if it is visible on the network.
  • Ensure that the network hardware is functioning correctly for the connection path to the resource manager.
  • Ensure that the correct switch and firewall ports are enabled for the resource. For information about required ports, see Port availability – XClarity Orchestrator.
