You can test the negotiated (planned) switchover operation to confirm uninterrupted data availability.
About this task
This test validates that data availability is not affected (except for Microsoft Server Message Block (SMB) and Solaris Fibre Channel protocols) by switching the cluster over to the second data center.
This test should take about 30 minutes.
This procedure has the following expected results:
For MetroCluster IP configurations:
- For ONTAP 9.4 and earlier:
- Mirrored aggregates will become degraded after the negotiated switchover.
- For ONTAP 9.5 and later:
- Mirrored aggregates will remain in normal state if the remote storage is accessible.
- Mirrored aggregates will become degraded after the negotiated switchover if access to the remote storage is lost.
- For ONTAP 9.8 and later:
- Unmirrored aggregates that are located at the disaster site will become unavailable if access to the remote storage is lost. This might lead to a controller outage.
