4. Confirm that the XP Continuous Access Journal S-VOL has changed to SMPL status.
5. When the XP Continuous Access Journal S-VOL status changes to SMPL, use that volume and
resume the business tasks on the remote site.
Note: Unlike the 3DC cascading configuration, the 2DC configuration does not allow you to
continue your business tasks on the intermediate site. To transfer the business tasks back to the
primary site from the remote site, you need to copy the data from the remote to the primary site
by using the initial copying of XP Continuous Access Synchronous. In addition, after you transfer
the business tasks to the primary site, delete the XP Continuous Access Synchronous S-VOL and XP
Continuous Access Journal primary data volume in the intermediate site.
Use the remote command device for XP Continuous Access Journal and XP Continuous Access
Synchronous pair operations if the intermediate site does not connect to the host. For information
about the remote command device, see the HP XP24000/XP20000 External Storage Software
User Guide.
