Activating Disaster Recovery
Activate DR when a volume or site becomes unavailable. When DR is activated, a view volume of the original destination volume
(replication) or secondary volume (Live Volume) is brought on line and mapped to a server at the DR site. Before DR can be
activated for a volume, at least one snapshot must have been Replicated to the DR site.
Types of Disaster Recovery Activation for Live Volumes
Storage Center supports two types of Disaster Recovery for Live Volumes:
● Preserve Live Volume: Directs IO requests to the secondary volume by promoting it to primary. The Live Volume is not
deleted and may be repaired when an administrator restores the volume after the source Storage Center comes back online.
Volume identity is preserved so that administrator intervention is not required on the servers mapped to the volume. If a
replication is managed by the Live Volume, the managed replication is preserved and follows the DR-activated volume.
● Recreate Live Volume: If Preserve Live Volume is not selected or not available, Unisphere Central deletes the Live
Volume, creates a view volume, and maps it to a server. During the recovery process, the Live Volume is recreated. If a
replication is managed by the Live Volume, the managed replication is removed during the recovery process.
