Creating cluster peer relationships
You can create a cluster peer relationship to connect clusters together so that the clusters in a peer relationship can communicate with each other.
Before you begin 
•
The time on the clusters that you want to connect using an intercluster network must be synchronized within 300 seconds (5 minutes).
Cluster peers can be in different time zones.
•
Ports with intercluster role must be created if you want to use intercluster ports.
•
Each intercluster LIF must have an IP address that is dedicated for intercluster replication.
•
The correct maximum transmission unit (MTU) value must be used on the network ports that are used for replication.
The network administrator can identify which MTU value to use in the environment. The MTU value should be set to a value that is supported by the network end point to which it is connected. The default value of 1500 is correct for most environments.
•
All paths on a node that are used for intercluster networking should have equal performance characteristics.
•
The intercluster network must provide connectivity among all the intercluster LIFs on all the nodes in the cluster peers.
Each intercluster LIF on all nodes in a cluster must be able to connect to every intercluster LIF on every node in the peer cluster.
•
To use ports with the intercluster role, the intercluster ports must be created before configuring cluster peering. System Manager automatically creates the intercluster LIFs.
About this task 
While creating a cluster peer relationship, you have to set the following attributes in the Cluster Peer Create wizard:
•
Create an intercluster LIF on each node in the cluster, if it is not already configured.
Intercluster LIFs can be configured on data ports or intercluster ports
•
Specify the name and credentials of the remote cluster.
•
Specify the IP address and port number of the LIFs on the remote cluster that are used for intercluster communication.
Steps 
1.
From the Home tab, double-click the appropriate storage system.
2.
Expand the Cluster hierarchy in the left navigation pane.
3.
Click Configuration > Peers.
4.
Click Create.
5.
Type or select information as prompted by the wizard.
6.
Confirm the details and click Finish to complete the wizard.
