Tasks for setting up DR in a non-shared storage environment
The following table outlines the high-level objectives and tasks for a creating a single-node DR configuration at the secondary site. Refer to this table if you are setting up DR in a non-shared storage environment (dynamic disk groups configured using VMNSDg agent).
You cannot use the DR wizard to configure disaster recovery in a non-shared storage environment. You have to configure DR manually.
Note: Some procedures (for example, configuring Volume Replicator replication) are common if you are setting up a DR or an RDC configuration. To avoid duplication, the topics referenced in this table point to the procedures described in the RDC chapter covered earlier.
