Cannot connect a resource manager

Use this information to troubleshoot issues when connecting a resource manager.

  • Ensure that the credentials are correct for the resource manager and that the password is not expired.
    Note
    Ensure that the password follows the security and password policies for the device. Security and password policies might vary.
  • Ensure that the resource manager does not have the maximum number of supported data forwarders. XClarity Orchestrator creates an event forwarder in the Lenovo XClarity Administrator resource manager when a connection is created to that resource manager.
  • Ensure that the event forwarder in the XClarity Administrator resource manager is enabled.
  • Ensure that the resource manager is at a supported version. For a list of supported devices, see Supported hardware and software – XClarity Orchestrator.
  • Ensure that the resource manager is reachable on the network from XClarity Orchestrator and that XClarity Orchestrator is reachable on the network from the resource manager.
  • Ensure that the correct ports are open in the firewall. For information about port requirements, see Port availability.
  • If the resource manager's certificate is signed by an external certificate authority (CA), ensure that the CA certificate and any intermediate certificates are imported into the XClarity Orchestrator truststore (see Working with security certificates).
  • When connecting a resource manager that has an externally signed certificate:
    • Ensure that it is an X.509 v3 certificate. XClarity Orchestrator cannot connect to a resource manager that has an externally signed v1 certificate.
    • Ensure that the certificate details include the following requirements.
      • KeyUsage must contain
        • Key Agreement
        • Digital Signature
        • Key Encipherment
      • Enhanced Key Usage must contain
        • Server Authentication (1.3.6.1.5.5.7.3.1)
        • Client Authentication (1.3.6.1.5.5.7.3.2)
