Which process needs to be run before automatic failover can occur?

In IBM Spectrum Protect, automatic failover can occur when a primary node fails and a secondary node takes over its responsibilities. In order for this to work, the secondary node must be an exact copy of the primary node. This is achieved through node replication, which synchronizes the data and configuration between the primary and secondary nodes.

Node replication is a process that needs to be set up and run before automatic failover can occur. It involves creating a copy of the primary node and configuring it as a secondary node. The data and configuration are then synchronized between the two nodes, either continuously or on a schedule.

Once node replication is set up, the secondary node can take over the primary node's responsibilities in the event of a failure, without any interruption in service.

To summarize, node replication is the process that needs to be run before automatic failover can occur in IBM Spectrum Protect.
