Configuring Replication for a Clustered Configuration

This task describes how to configure replication in a clustered environment. Follow these steps to configure replication properly to ensure that projects continue to replicate after a cluster takeover, cluster failback, or after performing reverse replication on a target appliance.

Before You Begin

If you are configuring replication for clustered appliances for the first time, review Example: Replication Configuration for Clustered Appliances.

1. On the replication source and target appliances, select network interfaces and IP addresses to be used for replication traffic, using these guidelines:
   1. Always select a singleton network interface to ensure it is taken over by the peer node after a cluster takeover or failback operation.
   2. On the source system, ensure that the selected network interface and the storage pool, from which the data will be replicated, are both assigned to the same node. This is always the case when the source cluster is in the CLUSTERED state.
   3. On the target system, assign the selected network interface on the target appliance and the storage pool, into which the replicated data will be put, to the same node. This maintains the association when the replication configuration is performed while the target cluster is in the CLUSTERED state.
   4. Ensure that the source and the target systems can communicate using the selected network interfaces and IP addresses.
2. On the source and target appliances, create static /32 (host-based) network routes using the selected network interfaces and IP addresses.
3. On the source appliance, configure the replication target object using the selected IP address of the target.
