the Live Volume, it moves to follow the newly promoted primary volume. Fewer volume settings are available because the existing
Live Volume settings are used.
If Preserve Live Volume is not selected, Storage Manager deletes the Live Volume, creates a view volume, and maps it to a
server. During the restore process, the Live Volume is recreated. If a replication is managed by the Live Volume, the managed
replication is removed later during the restore process.
5. In the Name field, type the name for the recovery volume.
6. Select a server to map the recovery volume to by clicking Change next to the Server label.
A server is required for each restore point unless the Preserve Live Volume check box is selected.
Click Advanced Mapping to configure LUN settings, restrict mapping paths, or present the volume as read-only.
7. Choose which snapshot will be used for the activated volume.
If Preserve Live Volume is not available or not selected, use the current state of the volume by selecting Use Active Snapshot,
or select a frozen snapshot by clicking Change next to Snapshot. By default, the last frozen snapshot is used.
If Preserve Live Volume is selected, the last frozen snapshot is used unless Use Active Snapshot is selected.
NOTE: For high consistency mode synchronous replications that are current, the Use Active Snapshot check box
is automatically selected.
8. (Optional) If Preserve Live Volume is not available or not selected, click Change next to Snapshot Profile List to specify which
snapshot profiles will be associated with the activated volume.

Access Data on an Original Primary Volume After DR Activation
If DR is activated for a Live Volume using the Preserve Live Volume option, the original primary Storage Center prevents the original
primary volume from being active until the Live Volume is restored. If you need to access data on the original primary volume before the
Live Volume is restored, use the Bring Primary Copy Online option to create a view volume of the original primary volume and map it to
the same server.
Prerequisites
DR must have been activated for the Live Volume with the Preserve Live Volume option selected.
About this task
The view volume that is created is not part of the Live Volume. Use this option only to access primary volume data while disaster
recovery is activated.
Volume identity is not preserved when the view volume is created, so the server may not recognize it as the original primary volume.
Steps
1. Click the Replications & Live Volumes view.
2. Click the Live Volumes tab.
3. Select the Live Volume, then click Bring Primary Copy Online. The Bring Primary Copy Online dialog box appears.
4. Click OK.
