How Can I Use the Secondary LUN in a Remote Replication Pair?
Question
How can I use the secondary LUN in a remote replication pair?
Answer
A remote replication pair consists of a primary LUN and a secondary LUN. The secondary LUN stores a data duplicate of the data on the primary LUN.
- In normal cases, the secondary LUN cannot be accessed by a host. To enable a host to access data on the secondary LUN, you can create a snapshot for the secondary LUN and map the snapshot to the host.
- When the primary LUN fails and services are interrupted, you must perform a primary/secondary switchover to change the secondary LUN to the primary LUN, and then map the new primary LUN to the host.
