Shutting Down and Restarting
The Polycom RealPresence DMA system’s Shutdown and Restart page lets you restart the system or turn it off completely. In a two-server cluster, you can shut down or restart either one or both servers in the cluster.
There is no mechanism for shutting down an entire supercluster at once. 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 cannot be made consistent with the rest of the supercluster.
Both shutting down and restarting will terminate all existing calls and log out all current users.
Do not 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 cannot be restarted without user input, requiring a keyboard and monitor.
Restart or Shut Down One or Both Servers in a Cluster
From the Shutdown and Restart page, you can restart or shut down one or both servers in a cluster.
To restart or shut down one or both servers in a cluster
1Go to Admin > 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:
ØTo restart the selected server(s), click Restart.
ØTo 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 servers reboot and the conference service becomes available again when the restart is complete. If you chose Shut Down, the servers 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.
Start Up a Shut-Down Cluster
Follow this procedure to start up a cluster that has been powered down.
To start up a shut-down cluster
1Turn on the first server in the cluster.
The server boots, which takes several minutes.
2Wait at least one minute and turn on the second server in the cluster.
The second server boots. When done, the LCDs of both the servers display DMA Clustered (applies to Polycom Rack Server 630 or 620-based systems only).
To start up all clusters in a supercluster, repeat the above procedure on each additional cluster, waiting at least five minutes between clusters. After all clusters have restarted, it may take up to 30 minutes for all supercluster-wide replication to complete.
