Before you configure the agent for Hitachi TrueCopy/Hewlett-Packard XP Continuous Access

Before you configure the agent, review the following information:

  • Verify that you have installed the agent on all the cluster nodes.

  • Verify the hardware setup for the agent.

    See Typical Hitachi TrueCopy/Hewlett-Packard XP Continuous Access setup in a VCS cluster.

  • Make sure that the cluster has an effective heartbeat mechanism in place.

    See About preventing split-brain.

  • Set up system zones in replicated data clusters.

  • Verify that the clustering infrastructure is in place.

    • If you plan to configure the agent in a global cluster, make sure the global service group for the application is configured.

      For more information, refer to the Cluster Server Administrator's Guide.

    • If you plan to configure the agent in a replicated data cluster, make sure the required replication infrastructure is in place and that the application is configured.

  • Ensure that the HORC manager is configured to access the device groups.

    • Verify that the HTC instance is configured appropriately and is in a running state.

    • Verify that the HORC manager CLIs execute successfully. This is essential for the HTC and the HTCSnap agents to be able to fetch HTC-related data and to succesfully perform failover, switchover, and other operations.
