About this task
In a case of a disaster, one of the failover steps is to map the target dataset to the host, so the dataset will be able to serve IO. It is possible to prepare the remote site beforehand, so in the case of a failover the target dataset will already be mapped to the host. Throughout the normal operation of the replica, the target dataset is connected to the host in a read-only mode. It is serving host IO only upon a failover.
