Complete this task to confirm the volume pairs on which the disaster
recovery failback operation will be run. The failback operation copies all
modified tracks from a target volume to a source volume.
You must first create a remote mirror and copy volume pair. Before
you run the failback operation, the volumes must be full duplex. You must
create a path between the LSSs from the target site to the source site and
from the source to the target site.
When you are ready to return to Site A (your production site),
use the failback operation (on the Volume A-Volume B pair) from Site B (your
recovery site). This process makes the target volume (Volume B) transition
to a source and the original source volume (Volume A) transition to a new
target volume. The process will resynchronize the volumes with those at Site
A. At Site B, ensure failback process is complete and that the volume pair
is duplex.
Perform
the following steps to confirm which volume pairs a failback operation is
run against.
- In the navigation, select . Select the volume pair that the failover operation was performed against. The status of the volume pair should display as Suspended.
- Select Recovery Failback from the Select Action drop-down menu
and then click OK.
- A table displays showing the volume pairs in which the failback
process will occur. The status of the volume pairs should display
as Suspended.
- Click OK to complete the process. Otherwise,
click Cancel and your selection is canceled and the
page closes.
