Discovering and managing devices
Lenovo XClarity One discovers and manages supported devices through XClarity One Hub.
Ensure that the devices that you want to manage are supported by the hub. You can find a complete list of supported devices, minimum required firmware levels, and limitations from the XClarity One Hub Support for Servers webpage.
To discover and manage devices, you must have device administrator privileges.
After the devices are managed, the hub polls each managed device every 24 hours to collect and send inventory data to XClarity One.
If XClarity One loses communication with a device (for example, due to power loss or network failure) while collecting inventory during the management process, the management completes successfully; however, some inventory information might be incomplete. Either wait for the device to come online and for XClarity One to poll the device for inventory or manually refresh inventory on the device.
If the IP address of a managed device changes, you must unmanage the device, and then manage it again.
You can use other management software (such as VMware vRealize Operations Manager) in tandem with XClarity One to monitor but not manage devices that XClarity One manages.
Discovering devices
The hubs automatically discover supported devices with baseboard management controllers in your environment by probing every five minutes for manageable devices that are in the same IP subnet as the hub using the SSDP protocol.
If devices were not or cannot be discovered automatically by a hub, you can manually discover those devices from the XClarity One portal. To discover devices, click the Device Management view, click Unmanaged Devices in the context menu, and then click the Add icon (
). When the wizard opens, select the type of device that you want to discover, and then follow the steps in the wizard to complete the process.
Devices can be discovered using specific IPv4 addresses, range of IP addresses, or by probing for manageable devices on specific IP subnets. IPv6 addresses are not supported.
The hub can discover a maximum of 20,000 devices in a single operation.
Lenovo Servers
These devices are discovered and managed through the baseboard management controller.
Lenovo ThinkAgile, ThinkEdge, and ThinkSystem servers are supported.
Migrate from LXCA
Devices are migrated from an existing Lenovo XClarity Administrator v4.3.4 or later instance to Lenovo XClarity One and a connected XClarity One Hub v1.5 or later. This transfers management of the devices to the target hub and imports artifacts such as firmware policies, device-settings configurations (configuration patterns), groups, service tickets, and XClarity Pro licenses into XClarity One. After the migration is complete, you can continue managing your device using XClarity One and the hub.
Managing devices
To manage discovered devices, click the Device Management view, click Unmanaged Devices in the context menu. Select the devices that you want to manage and click Manage devices icon (
). Follow the steps in the wizard to complete the process.
If a device is discovered by more than one hub, the device is listed on the Unmanaged Devices page for each hub that discovered it, ordered based on the discovery timestamp. When managing a device, you can choose the device that was discovered by the hub you want to use for management. A device can be managed by XClarity One through only one hub.
Unmanaging devices
You can unmanaged devices in your organization. Click the Managed devices panel title from the Device management view, select the devices that you no longer want to manage, and click the Unmanage icon (
).
The management user account (XC1_MGR_*), and event and metric subscriptions are removed from the device.
Sensitive information in the vault, inventory, vital product data, event forwarders between the device and the hub, and events and alerts that were raised by the device are discarded on the hub.
Events there were raised for the device by the hub are kept on the hub.
Device considerations
Some ThinkSystem servers support two XCC IP addresses. If two XCC IP addresses are present:
Ensure that each XCC IP address is configured on separate subnets.
The hub can use only one XCC IP address to manage a server. If the hub discovers two XCC IP addresses for the same server, only the IP address with the smaller number is listed in the discovered devices table.
The IP address that you use to manage the server becomes the management IP address. If there is a connectivity issue with the IP address, the hub does not failover to use the second XCC IP address.
Ensure that the management-controller date and time is synchronized with the NTP servers that are used by the hub. From the XCC user interface, click the Clock icon on the upper right corner to configure NTP settings.
Ensure that the LDAP setting on the XCC is set to LocalOnly before attempting to manage the devices. For more information, see Cannot manage a device.
Ensure that an operating system is installed, and that the server was booted to the OS, mounted bootable media, or efishell at least once so that the hub can collect inventory for those servers.
Ensure that IPMI over LAN is enabled. IPMI over LAN is disabled by default on these servers and must be manually enabled before the servers can be managed. To enable IPMI over LAN from ThinkSystem System Manager web interface, click . You might need to restart the server to activate the change.
