Commands for managing cluster peer relationships

There are specific Data ONTAP commands for managing cluster peer operations.

If you want to... Use this command...
Create an authenticated cluster peer relationship cluster peer create

This creates an authenticated cluster peer relationship by default. If you want to create an unauthenticated cluster peer relationship, you use this command with the -no-authentication parameter and unauthenticated cluster peer relationships must also be allowed by the cluster peer policy.

Create an authenticated cluster peer relationship with an extended authentication offer cluster peer create with the -offer-expiration parameter.

This is useful if the second cluster in the relationship cannot be authenticated in the default time of one hour.

Create an unauthenticated cluster peer relationship cluster peer create with the -no-authentication parameter.

Unauthenticated cluster peer relationships must also be allowed by the cluster peer policy.

Delete a cluster peer relationship cluster peer delete
Modify a cluster peer relationship cluster peer modify
Initiate an intercluster connectivity test cluster peer ping
Display information about the cluster peer relationship cluster peer show
Display TCP connection information for a cluster peer cluster peer connection show
Display health information of the nodes in a cluster peer relationship from the local cluster perspective cluster peer health show
Display information about outstanding authentication offers to peer clusters cluster peer offer show
Disable an existing cluster peer relationship cluster peer modify with the -auth-status-admin parameter set to revoked.
Update a cluster peer relationship to use authentication with a different passphrase cluster peer modify with the -auth-status-admin parameter set to use-authentication.

You can use this command to perform one of the following tasks:

  • Add authentication to an existing unauthenticated cluster peer relationship
  • Add authentication to a revoked cluster peer relationship
  • Change a passphrase for an authenticated cluster peer relationship
Reestablish a disabled cluster peer relationship with no-authentication cluster peer modify with the -auth-status-admin parameter set to no-authentication.
Modify an outstanding authentication offer to a peer cluster cluster peer offer modify with the -offer-expiration parameter.

You can change when the authentication offer expires if you determine that there is not enough time to authenticate the cluster peer relationship before the offer expires.

Cancel an outstanding authentication offer to a peer cluster cluster peer offer cancel
Display whether unauthenticated cluster peer relationships can exist and what the minimum passphrase character length is cluster peer policy show
Modify whether unauthenticated cluster peer relationships can exist and change the minimum passphrase character length cluster peer policy modify
