The Disaster Recovery Wizard requires that an existing storage layout for an application on a secondary site matches the primary site layout

Last published : Oct 01, 2026
The Disaster Recovery Configuration Wizard is designed to use for a new installation on the secondary site. Because it clones the storage, you do not need to configure the storage at the secondary site.
If you configure disk groups and volumes at the secondary site and install the application before you run the Disaster Recovery Wizard, the following limitations apply:
The wizard recognizes the storage at the secondary site only if it exactly matches the layout on the primary site. If there is a mismatch in volume sizes, the wizard can correct this. Otherwise, if the layout does not match, the wizard will not recognize that a storage layout already exists.(781923)
If it doesn't find a matching storage layout, the wizard will clone the storage from the primary site, if there is enough disk space. The result is two sets of disk groups and volumes:
  • The set of disk groups and volumes that you created earlier
  • The different set of disk groups and volumes that the wizard created by cloning the primary storage configuration
Workaround: If you have already created the storage layout at the secondary site and installed the application, use the Disaster Recovery Wizard only if the layout exactly matches the layout on the Primary site.
Otherwise, if the wizard creates a different set of disk groups and volumes than what you have created earlier, you must set up the application to use the disk groups and volumes created by the Disaster Recovery Wizard before you can continue with the wizard.
