Join Supercluster Dialog Box

In the Supercluster page’s action list, the Join Supercluster command lets you add a Polycom RealPresence DMA system to an existing supercluster or create a new one. It opens the Join Supercluster dialog box, where you can specify any cluster in the supercluster to join. If the cluster you specify isn’t already part of an existing supercluster, joining to it creates a new supercluster that gets its shared data store from the cluster you specify.

Note: Supercluster Software Versions Must Match

All the clusters in a supercluster must be running compatible software versions. Patch releases of the same major version will generally be compatible, but major version upgrades will not be compatible. If the software version of the system you’re adding isn’t compatible with the supercluster or cluster to which you’re joining it, a message tells you so and the join operation is terminated.

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 on page 30.

The following table describes the fields in the Join Supercluster dialog box.

Column	Description
Host name or IP address	Any existing cluster in the supercluster to which the Polycom RealPresence
	DMA system should be joined, or the system with which to form a new
	supercluster. We strongly recommend specifying the FQDN of the virtual
	management interface for the cluster to be joined.
User name	An administrator login name for the specified cluster.
Password	The password for the administrator login.

Supercluster Procedures

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.

To create or join a supercluster

1 Go to Network > RealPresence DMAs.
