Enabling Protection for Secondary Resources

This section describes how to ensure that only the data on primary resources in a remote replication pair can be written to secondary resources.

The remote replication pair for which you want to enable secondary resource protection has not been added to a consistency group.
Running Status and Secondary Resource Data Status of the remote replication pair support protection enablement. Table 1 describes in which status secondary resource protection can be enabled for a remote replication pair.
