23 About unsupported and unmanaged hardware

Unmanaged and unsupported devices are devices that the appliance does not manage. Adding unmanaged and unsupported devices to the appliance allow tracking, inventory, and power management.

23.1 How the appliance handles unsupported hardware

Unsupported hardware is any device that the appliance cannot manage. Unsupported devices are similar to unmanaged devices in that all unsupported devices are not managed by the appliance. The difference is that you can bring unmanaged devices under management of the appliance if you take the appropriate actions or properly configure them. Unsupported hardware can never be managed by the appliance.

The appliance detects the unsupported hardware and displays the model name and other basic information that it obtains from the device for inventory purposes. The appliance also accounts for the physical space unsupported devices occupy in enclosures and racks.

To account for the space a device occupies, the appliance represents unsupported hardware the same way it represents unmanaged devices.

The only action available for unsupported hardware is Remove.

23.2 About unmanaged devices

An unmanaged device is a device, such as a server, enclosure, KVM (keyboard, video and mouse) switch, in-rack monitor/keyboard, or router, that occupies space in a rack and/or consumes power but is not managed by the appliance.

Unmanaged devices are created automatically to represent devices that are attached to an HP Intelligent Power Distribution Unit (iPDU) using HP Power Discovery Services connections. BladeSystem enclosures and HP ProLiant DL series servers are shown in the unmanaged or unsupported state in the Enclosures and Server Hardware in the master pane, respectively. These will be represented as unmanaged enclosures and servers; as such, they are not be included in the Unmanaged Devices resource list.

When creating an unmanaged device, you provide its name, model description, height in U-slots and maximum power requirements. These values are used in power and cooling capacity analysis and enables alerts to be generated identify potential power and cooling issues.

Because there is no communication to the unmanaged device, it is are always shown with disabled status unless appliance-generated alerts identify issues to be addressed.

For purposes of power configuration, unmanaged devices are assumed to have two power supply connections to support redundant power. These are identified as power supplies 1 and 2. If an unmanaged device does not support redundant power, connect only power supply 1, then clear the alert about lack of redundant power to the device.

For devices that are not discovered through HP Power Discovery Services connections, you can manually add these devices to the appliance for tracking, inventory, and power management purposes.
