Administrator Guide

Step 5C: The Source Volume is Activated
Storage Manager prompts the administrator to deactivate and unmap the destination volume. The source volume resumes replicating to
the destination volume, and the source volume is activated and mapped to the server at the source site.

Disaster Recovery Administration Options
Use Storage Manager to prepare for DR, activate DR, and restore failed volumes. To make sure that a site outage does not prevent you
from accessing Storage Manager to perform DR operations, you can optionally install a remote Data Collector at a DR site.
A remote Data Collector provides access to Storage Manager DR options when the primary Data Collector is unavailable. In the event that
the primary Data Collector is unavailable, use a locally installed Client to connect to the remote Data Collector.

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
• Predefining Disaster Recovery Settings for Replications
• Test Activating Disaster Recovery
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 QoS definitions 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.
