You can test the healing and manual switchback operations to verify that data availability is not affected (except for SMB and Solaris FC configurations) by switching back the cluster to the original data center after a negotiated switchover.
This test should take about 30 minutes.
The expected result of this procedure is that services should be switched back to their home nodes.
