Dell PowerFlex 4.5.x Technical Overview
Using replicated volumes
While replication is active, the target volumes remain inaccessible to the hosts with only limited read-only access permitted. This is done to maintain data integrity and consistency between the two peer systems. The data at the target can be accessed to test replication, create snapshots, and to fail over.
