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
On the recovering node, use the system configuration recovery cluster recreate command at the advanced privilege level to re-create the cluster.
Use the cluster identity show command to verify that the recovering node has a different UUID than the other nodes.
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. Do you
want to continue? {y|n}: y 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.
