Access Journal and XP Continuous Access Synchronous
If a disaster or a failure occurs on the primary site, which is part of the 2DC configuration by using
XP Continuous Access Journal and XP Continuous Access Synchronous with the system option mode
707, you can continue your business tasks by using the XP Continuous Access Journal secondary
volume on the remote site. In case of a disaster or a failure, first transfer the operations from the
primary to the remote site.
To transfer the business tasks to the remote site by using RAID Manager, execute the following
steps. For information on how to use RAID Manager, see the HP RAID Manager User Guide. For
information about the system behavior when the system option mode 707 is set to ON, see
“XP

Access Synchronous P-VOL in the primary site.
