Cloning the storage on the secondary site using the DR wizard (Volume Replicator replication option)
The DR wizard enables you to clone the storage configuration present at the primary site on to the secondary site. To do this successfully, the systems at the secondary site must have adequate free storage. If you have created the configuration but there is a mismatch in the volume sizes, the wizard can correct this and then complete the configuration.
Note: |
The DR wizard cannot be used if you are setting up DR in a non-shared storage environment. |
If you have not yet started the wizard, refer to the following topic before continuing with the storage cloning procedure:
