Suspending or unsuspending a virtual network function or a VDU that is part of it

You can suspend a virtual network function or a VDU that is part of it to free up the computational resources of the OpenStack cloud platform. This saves the state of the virtual network function or VDU to the disk of the OpenStack virtual platform. When you unsuspend the virtual network function or VDU, it begins consuming computational resources again. Processes running on a virtual network function or VDU are resumed from the point at which its state was saved.

To suspend or unsuspend a virtual network function or a VDU that is part of it:

1. On the self-service portal, go to the Catalog menu section.

   The network service management page is displayed.

2. In the Network services pane, click the previously deployed network service to whose topology the virtual network function has been added.

   The topology is displayed.

3. Click the virtual network function.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Flavours tab is selected, which displays flavours.

4. If you want to suspend or resume a virtual network function, in the upper part of the settings area, click Management → Suspend VNF → Power or Resume suspended VNF.
5. If you want to suspend or unsuspend a VDU that is part of the virtual network function:
   1. Select the VDU management tab.

      A table of VDUs is displayed.

   2. Click Management → Power → Suspend VDU or Resume suspended VDU next to the VDU that you want to suspend or reactivate.
6. In the confirmation window, click Apply.

The virtual network function or its VDU is suspended or unsuspended.
