What is a split brain in a MetroCluster configuration?
- Last Updated:
- ONTAP 9
- Data ONTAP 8
In a MetroCluster configuration, a split-brain occurs when both sites are serving the same data.
- ClusterA is running in a normal state serving it's own data.
- ClusterB has performed a Switchover and is serving both it's own data and ClusterA data.
This situation could occur if the communication between sites is lost, then a switchover on disaster is performed from one or both of the sites.
|Always ensure that the remote cluster is down before performing a switchover on disaster operation.|
