To start up a shut-down cluster

System Management and Maintenance

Caution: Always shut down properly

Don’t turn off a Polycom RealPresence DMA system server by simply unplugging it or otherwise removing power, especially if it’s going to remain off for some time. If a server loses power without being properly shut down, the RAID controller fails to shut down, eventually depleting its battery. If that happens, the server can’t be restarted without user input, requiring a keyboard and monitor.

There is no mechanism for shutting down an entire supercluster. If you want to shut down all clusters in a supercluster, you must do so one cluster at a time. Wait at least five minutes before shutting down the next cluster.

If you want to shut down a cluster in the supercluster while other clusters remain on, remove the cluster from the supercluster if it will remain shut down for more than a few hours. The supercluster retains only a limited amount of “playback” data that can be used to bring the shutdown cluster back up to date once it’s turned back on. If the cluster remains off long enough, its data store can’t be made consistent with the rest of the supercluster.

To restart or shut down one or both servers in a cluster

1Go to Maintenance > Shutdown and Restart.

The page displays the server or servers in the cluster, along with status information.

2Select the server(s) you want to shut down or restart.

3Do one of the following:

To restart the selected server(s), click Restart.

To shut down the selected server(s), click Shut Down.

4When asked to confirm that you want to restart or shut down, click Yes.

The system logs you out and the selected server(s) shut down. If you chose Restart, the server(s) reboot, and conference service becomes available again when the restart is complete (typically, this takes about five minutes).

If you chose Shut Down, the server(s) remain powered off until you manually turn them back on.

To shut down all clusters in a supercluster, repeat the above procedure on each additional cluster, waiting at least five minutes between clusters.
