You are installing a 4-node cluster with two CN1610 switches. Your co-worker is setting up the
switches, but accidentally deletes the current configuration.
According to NetApp, what is the recommended way to restore the configuration?

A.
Install only one switch.

B.
Manually configure the ports as they are designated in the CN1601 and CN1610 Switch Setup
and Configuration Guide.

C.
Reload the same reference file to the switch.

D.
Copy the configuration from a switch that is working.

Explanation:
You re-create the cluster using the cluster configuration that you chose and made
available to the recovering node, and then rejoin each additional node to the new cluster.
You should only perform this task to recover from a disaster that resulted in the loss of the
cluster’s configuration.
Steps
1. On the recovering node, use the system configuration recovery cluster recreate command at the
advanced privilege level to re-create the cluster.
2. Use the cluster identity show command to verify that the recovering node has a different UUID
than the other nodes.
3. For each node that needs to be joined to the re-created cluster, do the following:
3a. From a healthy node on the re-created cluster, use the system configuration recovery cluster
rejoin command at the advanced privilege level to rejoin the target node to the cluster.
Example
This example rejoins the target node (node2) to the re-created cluster.
cluster1::*> system configuration recovery cluster rejoin -node node2
Warning: This command will rejoin node “node2” into the local
cluster, potentially overwriting critical cluster
configuration files. This command should only be used
to recover from a disaster. Do not perform any other
recovery operations while this operation is in progress.
This command will cause node “node2” to reboot.

The target node reboots and then joins the cluster.
3b. Use the cluster show command with the -eligibility parameter to verify that the target node is
healthy and has formed quorum with the rest of the nodes in the cluster.
The target node must rejoin the re-created cluster before you can rejoin another node. Restoring a cluster configuration from an existing configuration
