Configuring global clusters

If you had installed a valid HA/DR license, the installer provides you an option to configure this cluster as global cluster. If not, the installer proceeds to configure VCS based on the configuration details you provided. You can also run the gcoconfig utility in each cluster later to update the VCS configuration file for global cluster.

You can configure global clusters to link clusters at separate locations and enable wide-area failover and disaster recovery. The installer adds basic global cluster information to the VCS configuration file. You must perform additional configuration tasks to set up a global cluster.

See Veritas Cluster Server User's Guide for instructions to set up VCS global clusters.

Note:

If you installed a HA/DR license to set up replicated data cluster or campus cluster, skip this installer option.

To configure the global cluster option

  1. Review the required information to configure the global cluster option.

  2. Specify whether you want to configure the global cluster option.

    Do you want to configure the Global Cluster Option? [y,n,q] (y)

    If you skip this option, the installer proceeds to configure VCS based on the configuration details you provided.

  3. Provide information to configure this cluster as global cluster.

    The installer prompts you for a NIC, a virtual IP address, value for the netmask, and value for the network hosts.

    You can also enter an IPv6 address as a virtual IP address.

  4. Verify and confirm the configuration of the global cluster.

        Global Cluster Option configuration verification:
    
        NIC: lan0
        IP: 192.168.1.16
        Netmask: 255.255.240.0
        NetworkHosts: 192.168.1.15
        Is this information correct? [y,n,q] (y)
