Hard reboot of VNFs and VDUs

Expand all | Collapse all

A hard reboot can be used to restore normal operation of a VNF/VDU if it is unresponsive or if multiple severe system errors occur. When performing a hard reboot, the VNF/VDU goes through a power off/power on cycle and subsequently returns to its last stable state.

Note that a hard reboot may cause the VNF/VDU to become temporarily unavailable.

We recommend using a hard reboot only if all other problem resolution measures, including a soft reboot, have been unsuccessful.

To hard-reboot a VNF/VDU, use the following instructions:

• Hard reboot of a VNF.

     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 button .
