Placing device components into unmanaged state

Place device components, including interfaces, into unmanaged state so that engineers can work on the device and its components to resolve a problem.

Placing device components into unmanaged state deactivates Network Manager polling and event correlation for the components.
Note: The event list still displays events for the components generated due to polling by other Network Manager software, such as Tivoli Netcool/OMNIbus. You can configure the event list to filter out or to tag these events.

Complete these steps from the Structure Browser.

The Structure Browser has two display modes: tree and table. The tree mode can be accessed by right-clicking a device and selecting Show Device Structure; the tree is also available as a widget. The table mode is shown underneath the Hop View in a default installation. The table is only available from a widget.

  1. From the Structure Browser, identify a device with components that you want to change from managed state to unmanaged state and proceed as follows.
    • From the tree, double-click the device.
    • From the table, click Show interfaces or Show device connectivity.
  2. Identify the managed device components that you want to change to unmanaged and click Tools > Unmanage.
A wrench icon Default alert status icon for unmanaged nodes or devices. appears next to the selected components indicating that these components are now in unmanaged state. Polling and event correlation stops for these components.
