You can start a FlashCopy® consistency group
from the Starting FlashCopy Consistency Groups
panel in the SAN Volume Controller Console.
Actions
The
following actions are available:
Start
Click this button to start a FlashCopy consistency
group.
Cancel
Click this button to exit the panel without starting a FlashCopy consistency group.
Starting FlashCopy consistency group–Prepare and start
Use the Starting FlashCopy Consistency Group panel in the SAN Volume Controller Console to
prepare and start the FlashCopy consistency group. This panel displays
if the SAN Volume Controller cluster
detects that the FlashCopy mapping is not in the Prepared state. Before FlashCopy mappings in the selected FlashCopy consistency
can start, all the mappings must first be prepared. When the FlashCopy
mappings are prepared, any data that resides in the cache for the
source virtual disks (VDisks) is transferred to disks thus ensuring
that the copy operation contains all data currently on the source
VDisks. After the preparation action completes for the FlashCopy mappings
in the consistency group, the system starts the FlashCopy consistency
group.
Starting FlashCopy consistency groups–Restore
Use the Starting FlashCopy Consistency Group–Restore
panel in the SAN Volume Controller Console to
start a selected FlashCopy consistency group for restoring data. This
panel indicates that the selected FlashCopy consistency group has
mappings where target virtual disks (VDisks) are also source VDisks
in other active FlashCopy mappings. When the FlashCopy consistency
group is being started with restore option, the start operation can
fail if dependencies exist between the any of the FlashCopy mapping
in the consistency group and other FlashCopy mappings on the cluster
that have also been started with the restore option. To determine if dependencies
exist between the selected FlashCopy mappings
and other mappings, use the Viewing FlashCopy Mappings panel to determine whether
other FlashCopy mappings
are linked to the selected mapping through shared source or target
VDisks. If the restore option is set on any of these linked mappings,
then you cannot start the selected FlashCopy mapping
with the restore option.
