Promoting a backup registry host to primary registry host

Use the rgy_switchover command to promote the backup registry server, and then reconfigure each registry client to use the new server.

About this task

This scenario assumes that the rgy_backup program has been running successfully on backup registry host rgy2. When the primary registry host rgy1 fails, you can use rgy_switchover to promote rgy2 to primary registry host. When rgy1 becomes available again, you use rgy_backup and then rgy_switchover to return rgy1 to the role of primary registry host.

To promote the backup registry host:
  1. Run rgy_switchover. Make rgy2 the primary registry host. Make rgy3 the new backup registry host:
    rgy_switchover –backup rgy3 rgy1 rgy2
  2. Reconfigure client hosts. Client hosts that were online and running the location broker (albd) at switchover time need not be reconfigured to recognize the new primary registry host. The rgy_switchover command does not update client hosts to indicate that a new primary registry host is in use. You must reconfigure the other client hosts manually, following the procedure in Defining an HCL VersionVault registry host, when they become available.
  3. Configure a new backup registry host. Configure an additional backup registry host to provide continuing rgy_switchover capability while the primary registry host is down and the backup registry host is functioning as the primary registry host. Follow the procedures in Defining a backup registry host.
