Supercluster Procedures Superclustering

Note

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 DMA System” on page 24.

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

Table 9-2Join Supercluster dialog box

Column	Description
Host name or IP	Any existing cluster in the supercluster to which the
address	Polycom 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

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.
