How Do I Use the Secondary LUN in a Remote Replication Task

How Do I Use the Secondary LUN in a Remote Replication Task

Question

How do I use the secondary LUN in a remote replication task?

Answer

The primary LUN and the secondary LUN in a remote replication form a pair, and the secondary LUN stores a data duplicate for 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 causes service interruption, 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.
