Hub connection and management

Lenovo XClarity One monitors and manages devices through one or more light-weight device managers, called hubs. Hubs are installed on premise in your data centers. They can be set up across multiple sites, where your devices are located. The hubs are the only devices that communicate directly with the XClarity One portal.

Hubs are installed on premise in your data centers and then connected to XClarity One. They can be located across multiple sites where your devices are located.

Note
At least one hub must be installed and connected to XClarity One for each organization.

Before you add (connect) a hub to the XClarity One portal, ensure that:

  • The hub is installed and configured (see Setting up a hub).

  • Ensure that the hub is online and reachable on the network from XClarity One.

  • Ensure that you have the correct privileges to add a hub. You must be a hub administrator.

Adding a hub to XClarity One is a two-step process that involves installing a registration key from the hub to the XClarity One portal and installing a registration key from the XClarity One portal to the hub (see Connecting the hub to XClarity One).

When you add a hub, XClarity One retrieves information about all devices that are managed by the hub.

When you remove (disconnect) a management hub, XClarity One deletes information about the hub and its managed devices from its own data repository. However, the hub itself retains information about its managed devices and continues to manage those devices.

When you disable a hub, information about the hub and its managed devices is retrained; however, the management hub and its managed devices are not accessible to XClarity One.

Tip
If XClarity One loses connection to a hub (for example, if there are network issues or if you use the XClarity One Hub web interface to disconnect the hub from XClarity One), XClarity One is unable to retrieve the latest information from the hub, including job progress, until the connection between the hub and XClarity One is reestablished (network issues are resolved or you reconnect the hub).

Connecting a hub​

After you connect (register) Lenovo XClarity One Hub to the Lenovo XClarity One portal, you can begin managing and monitoring your devices.

Disconnecting a hub​

If you disconnect this hub, all data for the hub is removed from the XClarity One portal; however, device and system data is retained in the hub. The hub continues to manage devices and receive data from those devices. If you reconnect this management hub to the XClarity One portal, these devices show up as managed devices.
