You can use System Manager to peer two clusters so that the peered clusters can coordinate and share resources between them.
More information
Prerequisites for cluster peering
Before you set up cluster peering, you should confirm that the connectivity, port, IP address, subnet, firewall, and cluster-naming requirements are met.
Creating cluster peer relationships
You can create an authenticated cluster peer relationship to connect clusters so that the clusters in the relationship can communicate securely with each other. You can use System Manager to configure an intercluster interface for the local cluster if the intercluster interface is not configured.
Modifying the cluster peer passphrase
For security reasons, you can modify the passphrase that is provided during cluster peer creation by using System Manager.
Modifying the peer network parameters
You can use System Manager to modify the IPspace and intercluster logical interfaces (LIFs) that are configured for the remote cluster. You can add new intercluster IP addresses or remove existing IP addresses.
Deleting cluster peer relationships
You can use System Manager to delete a cluster peer relationship if the relationship is no longer required. You must delete the cluster peering relationship from each of the clusters in the peer relationship.
What a cluster peer is
The cluster peer feature allows two clusters to coordinate and share resources between them.
What cluster peer intercluster connectivity is
Cluster peer intercluster connectivity consists of intercluster logical interfaces (LIFs) that are assigned to network ports. The intercluster connection on which replication occurs between two different clusters is defined when the intercluster LIFs are created. Replication between two clusters can occur on the intercluster connection only, regardless of whether the intercluster connectivity is on the same subnet as a data network in the same cluster.
