  1. In the top-level menu of the HCP System Management Console, select Services Replication.

  2. On the replication Links page, click the name of the link you want.

  3. On the replication link details page, click Link.

  5. In the Failover panel, click Automatic Failover Settings.

  6. In the Automatic Failover Settings section:

    • For an active/active link or an inbound active/passive link, in the Local System section:
      • To enable automatic failover to the current system, select Fail over automatically. Then, in the Automatically fail over link after loss of connectivity for field, type the number of minutes HCP should wait before automatically failing over the link after a loss of connectivity to the other system involved in the link. Valid values are integers in the seven through 9,999.
      • To disable automatic failover to the current system, deselect Fail over automatically.
      • For active/passive links only, to enable automatic failback to the other system involved in the link, select Complete recovery automatically. Then, in the Automatically complete recovery when synchronization is less than field, type the number of minutes the up-to-date-as-of time for the link must be less than before HCP should automatically fail back the link. Valid values are integers in the one through 9,999.
      • For active/passive links only, to disable automatic failback to the other system involved in the link, deselect Complete recovery automatically.
    • For an active/active link or an outbound active/passive link, in the Remote System section:
