For detailed information about how to use RAID Manager, see the HP RAID Manager User Guide.
When a disaster or failure occurs, the above procedure allows you to resume your business tasks
by using the XP Continuous Access Journal pair volume in the intermediate site. The XP Continuous
Access Journal volume in the intermediate site will contain the same data that are stored in the XP
Continuous Access Journal primary data volume in the primary site.
For detailed information about pair status of data volumes, see
Recovering from a Failure in the Intermediate Site in a 3DC Cascading
Configuration
A disaster or failure may occur in the intermediate site in a 3DC cascading configuration combining
XP Continuous Access Journal sites. If it occurs, use RAID Manager to perform the delta resync
operation (pairresync) for the XP Continuous Access Journal pair for delta resync operation in the
XP Continuous Access Journal primary site and the secondary site. This will define a XP Continuous
Access Journal pair in the XP Continuous Access Journal primary site and the XP Continuous Access
Journal secondary site. After that you can continue your business tasks by duplicating volumes.
