MetroCluster IP: Can you do a Negotiated Switchover (NSO) whilst a shelf is powered off?

Answer
- If the local plex/shelf is online and the remote plex/shelf is offline then the remote cluster can be switched over using NSO to the local cluster.

Additional Information
Data will be served from the plex(es) at the alternate site, so a switchover is not necessary if there is a shelf failure.
