To define the remote cluster and heartbeat

1. On the primary site, enable write access to the configuration:

   # haconf -makerw
   				

2. On the primary site, define the remote cluster and its virtual IP address.

   In this example, the remote cluster is clus2 and its IP address is 10.11.10.102:

   # haclus -add clus2 10.11.10.102
   				

3. Complete step 1 and step 2 on the secondary site using the name and IP address of the primary cluster.

   In this example, the primary cluster is clus1 and its IP address is 10.10.10.101:

   # haclus -add clus1 10.10.10.101
   				

4. On the primary site, add the heartbeat object for the cluster. In this example, the heartbeat method is ICMP ping.

   # hahb -add Icmp
   				

5. Define the following attributes for the heartbeat resource:

   • ClusterList lists the remote cluster.

   • Arguments enable you to define the virtual IP address for the remote cluster.

   For example:

   # hahb -modify Icmp ClusterList clus2
   # hahb -modify Icmp Arguments 10.11.10.102 -clus clus2
   				

6. Save the configuration and change the access to read-only on the local cluster:

   # haconf -dump -makero
   				

7. Complete step 4-6 on the secondary site using appropriate values to define the cluster on the primary site and its IP as the remote cluster for the secondary cluster.
8. Verify cluster status with the hastatus -sum command on both clusters.

   # hastatus -sum

9. Display the global setup by executing haclus -list command.

   # haclus -list
   					clus1
   					clus2
   				

   Example of heartbeat additions to the main.cf file on the primary site:

   .
   .
   remotecluster clus2 (
   Cluster Address = "10.11.10.102"
   )
   heartbeat Icmp (
       ClusterList = { clus2 }
       Arguments @clus2 = { "10.11.10.102" }
       )
   
   system galaxy (
       )
   .
   .

   Example heartbeat additions to the main.cf file on the secondary site:

   .
   .
   remotecluster clus1 (
       Cluster Address = "10.10.10.101"
       )
   
   heartbeat Icmp (
       ClusterList = { clus1 }
       Arguments @clus1 = { "10.10.10.101" }
       )
   
   system mercury (
       )
   .
   .

   See the Veritas Cluster Server Administrator's Guide for details for configuring the required and optional attributes of the heartbeat object.
