Accessing the data from the backup system as if it were the primary system

If you do not think the data center system can be recovered in time or at all, then you will want to temporarily access the data from the backup system as if it were the primary system. You can again create a snapshot of the secondary volume and map that to hosts, or delete the replication set to allow mapping the secondary volume directly to hosts. Deleting the replication set means the secondary volume becomes a base volume and is no longer the target of a replication. Should the primary volume become available and you want to use it as is in preparation for another disaster, a new replication set with a new secondary volume must be created. Deleting the replication set also enables cleaning up any leftover artifacts of the replication set.

In an emergency situation where no connection is available to the peer system and you do not expect to be able to reconnect the primary and secondary systems, use the local-only parameter of the delete replication-setand delete peer-connection CLI commands on both systems to delete the replication set and peer connection. Do not use this parameter in normal operating conditions. For more information, see the Dell PowerVault ME4 Series Storage System CLI Guide. Other methods for deleting replication sets and peer connections will most likely be ineffective in this situation.
