Configuring the Steward Process (Optional)

In case of a two-cluster GCO, you can configure a Steward to prevent potential split-brain conditions, provided the proper network infrastructure exists. For more information about the Steward mechanism, see The Steward Process: Handling Split-brain in Two-Cluster Global Clusters

  To configure the Steward process (optional)

1. Identify a system that will host the Steward process. Make sure both clusters can connect to the system through a ping command.
2. Copy the file steward from a node in the cluster to the Steward system. The file resides at the path /opt/VRTSvcs/bin/.
3. In both clusters, set the Stewards attribute to the IP address of the system running the Steward process. For example:
   cluster cluster1938 (
    UserNames = { admin = gNOgNInKOjOOmWOiNL }
    ClusterAddress = "10.182.147.19"
    Administrators = { admin }
    CredRenewFrequency = 0
    CounterInterval = 5
   Stewards = "10.212.100.165"
    }
4. On the system designated to host the Steward, start the Steward process:
   # steward -start

   To stop the Steward process, use the following command:

   
   # steward -stop
