Saving and Validating Restore Points
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.
Prerequisite
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.
