Supercluster Procedures
To create or join a supercluster
1 Go to Network > RealPresence DMAs.
2 In the Actions list, click Join Supercluster.
3 In the Join Supercluster dialog, do one of the following:
To create a new supercluster, enter the FQDN or host name of the virtual management interface
for the other Polycom RealPresence DMA cluster with which to form the supercluster. Be sure the
other cluster is the one whose data store you want shared with the supercluster.
To add this system to an existing supercluster, enter the FQDN or host name of the virtual
management interface of one of the clusters in the supercluster.
4 Enter the user name and password with which to log into the Polycom RealPresence DMA cluster
you specified.
5 Click OK.
A prompt warns you that the system will restart and local data will be overwritten, and asks you to
confirm.
6 Click Yes.
The cluster you’re logged in to connects to the cluster you specified and establishes or joins the
supercluster. It obtains supercluster-wide configuration and data (this may take a few minutes). A
dialog informs you when the process is complete and the cluster is ready to restart. Shortly after that,
the cluster logs you out and restarts.
7 Click OK to log out immediately, or simply wait.
Note: Verify DNS records
Prior to creating a supercluster, we recommend verifying that DNS can resolve all FQDNs of all
clusters to become part of the supercluster. To do so, go to Maintenance > Troubleshooting Utilities
> Ping and ping the FQDNs (virtual and physical) of the other cluster(s). Do this on each cluster.
Note: Allow supercluster join operations to complete
You can only add one cluster to a supercluster at a time. Wait until the current join operation is
completely finished before attempting to add another cluster to the supercluster. The join operation
may take several minutes, and the time required increases as the number of clusters in the
supercluster increases.
Note: Create required DNS records
You may specify an IP address instead, but the host names (virtual and physical) of every cluster in
the supercluster must be resolvable by all the other clusters. For a superclustered system, A/AAAA
records on your DNS server(s) for each physical host name, physical IP address, and virtual host
name are mandatory. See Add Required DNS Records for the Polycom RealPresence DMA System.
Note: Restart your browser
You may need to restart your browser or flush your browser cache in order to log back into the system.
