Enabling Protection for a Secondary Resource

After secondary resource protection is enabled for a remote replication pair, the secondary dtree no longer receives read and write requests from hosts and only receives remote replication requests from the primary dtree.

Prerequisites

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.
