Creating the cluster peer relationship

You create the cluster peer relationship using a set of intercluster logical interfaces to make information about one cluster available to the other cluster for use in cluster peering applications.

Before you begin

Intercluster LIFs should be created on all of the nodes of both clusters you want to peer
You should ensure that the intercluster LIFs of the clusters can route to each other.
If there are different administrators for each cluster, the passphrase used to authenticate the cluster peer relationship should be agreed upon.

Steps

Create the cluster peer relationship on each cluster by using the cluster peer create command.
The passphrase that you use is not displayed as you type it.

Example
In the following example, cluster01 is peered with a remote cluster named cluster02. Cluster01 is a two-node cluster that has one intercluster LIF per node. The IP addresses of the intercluster LIFs created in cluster01 are 192.168.2.201 and 192.168.2.202. Similarly, cluster02 is a two-node cluster that has one intercluster LIF per node. The IP addresses of the intercluster LIFs created in cluster02 are 192.168.2.203 and 192.168.2.204. These IP addresses are used to create the cluster peer relationship.
```
cluster01::> cluster peer create -peer-addrs 192.168.2.203,192.168.2.204
Please type the passphrase: 
Please type the passphrase again:
```
```
cluster02::> cluster peer create -peer-addrs 192.168.2.201,192.168.2.202
Please type the passphrase: 
Please type the passphrase again:
```
If DNS is configured to resolve host names for the intercluster IP addresses, you can use host names in the –peer-addrs option. It is not likely that intercluster IP addresses frequently change; however, using host names allows intercluster IP addresses to change without having to modify the cluster peer relationship.

Display the cluster peer relationship by using the cluster peer show command with the -instance parameter.

Displaying the cluster peer relationship verifies that the relationship was established successfully.

Example

cluster01::> cluster peer show –instance
Peer Cluster Name: cluster02
Remote Intercluster Addresses: 192.168.2.203,192.168.2.204
Availability: Available
Remote Cluster Name: cluster02
Active IP Addresses: 192.168.2.203,192.168.2.204
Cluster Serial Number: 1-80-000013

Preview the health of the nodes in the peer cluster by using the cluster peer health show command.

Previewing the health checks the connectivity and status of the nodes on the peer cluster.

Example

cluster01::> cluster peer health show
