Recovering the Primary Site from a Failure When the System Consists of
Multiple Primary and Secondary Storage Systems
If a disaster or a failure occurs on the primary site, where the system consists of multiple primary
and secondary storage systems, you can continue the business tasks in the remote site and maintain
the data consistency in the consistency group. If a disaster or a failure occurs on the primary site,
first transfer the tasks from the primary to the secondary site.
To transfer the business tasks to the secondary site by using RAID Manager:
1. Switch the operations from the primary to the secondary site.
2. Specify the swap option and split the pair (pairsplit-RS).
3. Confirm that the status of all XP Continuous Access Journal secondary volumes in every
secondary storage system become SSWS.
4. Using the volumes in SSWS status in the secondary storage systems, resume the business tasks
on the secondary site.
For information on how to use RAID Manager, see the HP RAID Manager User Guide.
