You use the configuration from either a node in the cluster or a cluster configuration backup file to recover a cluster.
If the cluster consists of more than one node, and one of the nodes has a cluster configuration from when the cluster was in the desired configuration, then you can recover the cluster using the configuration stored on that node.
In most cases, the node containing the replication ring with the most recent transaction ID is the best node to use for restoring the cluster configuration. Use the cluster ring show command at the advanced privilege level to view a list of the replicated rings available on each node in the cluster.
If you cannot identify a node with the correct cluster configuration, or if the cluster consists of a single node, then you can use a cluster configuration backup file to recover the cluster.

|At a remote URL||Use the system configuration backup download command at the advanced privilege level to download it to the recovering node.|
