Considerations
•
You can use the GUI, jobs, or the CLUI. See DR groups Actions cross reference .
•
Guidelines apply. See Remote replication guidelines .
•
HP recommends that you not fail over a DR group pair more often than every 15 minutes.
•
To fail over a DR group pair, you must specify the destination DR group. See DR group pair .
•
You cannot fail over a DR group pair if remote replication is suspended or if a remote copy
(virtual disk) is in an unknown state. See DR groups
Suspension state and virtual disks resource
states .
•
If supported by controller software, an option is available to suspend remote replication after
the failover. See
Controller software features - remote replication and DR groups Suspend on
failover .
IMPORTANT: Failing over a DR group pair impacts host I/O. Ensure that you understand
the potential impacts of performing a failover. For more information on failover, see the HP
P6000 Continuous Access Implementation Guide.
Procedure
This procedure uses the GUI.
1. In the navigation pane, select DR Groups.
2. On the List tab, select the destination group in the DR group pair to failover.
3. Select Actions > Failover.
The Confirm Failover window appears.
4. If supported by controller software, an option to suspend remote replication is enabled. Select
Suspend on failover to suspend remote replication immediately after the failover is executed.
IMPORTANT: Do not perform this action when the links are down, especially during an
unplanned failover. Doing so can create an invalid source-source configuration. See Invalid
DR group pair - source and source .
5. Click OK.
Forcing a full copy
Force a full copy in a DR group pair. See DR groups Full copy .
