Cannot manage a management hub

Ensure that the management hub is supported by Lenovo XClarity Orchestrator (see Supported hardware and software – XClarity Orchestrator).

Check the event log for any network events, and resolve the issues, if any.

Ensure that the network hardware is functioning correctly for the connection path to the management hub.

Ensure that the correct switch and firewall ports are enabled for the management hub. For information about required ports, see Port availability.

Ensure that the management hub has a valid network configuration by verifying that the IP address is valid for the network. You can also ping the management hub to test if it is visible on the network.

Ensure that the registration key that was generated by management hub is installed in XClarity Orchestrator, and ensure that the registration key was generated by XClarity Orchestrator is installed in management hub. If the registration key is not valid, generated and install a new key (see Connecting resource managers).

If the management hub’s server certificate is signed by an external certificate authority, ensure that the subject alternative names includes the fully-qualified domain name (FQDN) or IP address of the management hub, and the subject name be set to the FQDN of the management hub (see Installing a trusted, externally-signed XClarity Orchestrator server certificate).

If management-hub certificate was generated using the CSR:

• Ensure that the certificate contains the FQDN and IP Address as part of the subject alternative names.

• Ensure that the certificate is configured to be used as both a server certificate and as a client certificate.

If the management hub encountered an error while attempting to install the registration key, contact Lenovo Support for assistance.
