Disaster Recovery Administration Options
Use Unisphere Central to prepare for DR, activate DR, and restore failed volumes. To make sure that a site outage does not
prevent you from accessing Unisphere Central to perform DR operations, you can optionally install a remote Data Collector at a
DR site.
A remote Data Collector provides access to Unisphere Central DR options when the primary Data Collector is unavailable.
Preparing for Disaster Recovery
Prepare for DR by saving restore points, predefining DR settings, and testing those settings.
Perform these tasks to implement a DR plan:
Saving and Validating Restore Points on page 253
Defining Disaster Recovery Settings for Replications on page 255
Test Activating Disaster Recovery on page 256
Saving and Validating Restore Points
A restore point includes information about a replication or Live Volume, including the source and destination volumes, source and
destination Storage Centers, and the Bandwidth Controls used. If a Storage Center goes down, this information becomes the
basis for restoring the replication or Live Volume.
A restore point for a Live Volume that manages a replication does not contain information about the managed replication.
If DR is activated for the Live Volume using the Preserve Live Volume option, the managed replication continues to
operate and follows the DR-activated volume.
If DR is activated for the Live Volume without using the Preserve Live Volume option, the managed replication is
removed and must be re-created manually.
A restore point for a replication that is managed by a Live Volume does not contain information about the Live Volume. If DR
is activated for the managed replication, the Live Volume must be re-created manually.
Save Restore Points for All Replications and Live Volumes
Save restore points for all replications and Live Volumes from the Disaster Recovery view.
