Overview of the unplanned failover process
In some cases (for example, unexpected equipment failure), you may need to run an unplanned failover for replication. The unplanned failover process differs from the planned failover process.
If cluster A is the original source cluster that replicates data to cluster B which is the original destination cluster and if cluster A fails unexpectedly, you can perform an unplanned failover or a disaster recovery. This marks the cluster B as the new source cluster and you can access the data/applications replicated to it.
For unplanned failover, run the following command from the original destination cluster (cluster B):
Replication> continuous failover fs_name
Where fs_name is the name of the file system which is configured under continuous replication.
Once an unplanned failover happens, the destination cluster (cluster B) becomes the new source cluster. It onlines the file system at the new source cluster (cluster B).
Note:
Though the commands used for planned and unplanned failover are the same, the intention and pre-requisites are different. For unplanned failover, the source cluster should be unreachable from the destination cluster.
