This article covers on how to recover a system volume like ONTAP's Metadata Volumes (MDV) from this situation. The instructions for restoring access to data volumes can be found here. To identify if a volume is in an nvfailed state, run the following command: In the above example, no volume is in nvfailed state. In the above example, one volume is in the nvfailed state.

The primary factor used to determine suitable a port to be used for placement is reachability, as determined by an ARP broadcast. The broadcast is triggered from each connected port on the site with the -mc vserver, the destination for the LIF in event of switchover. If the port already hosts its own LIF in the same subnet a broadcast is not sent.
