Manual switchover to the mate VSR-NRC

The NRC-P provides an API to perform a manual switchover to the mate VSR-NRC. This could be used, for example, to revert the active role back to a recovered primary VSR-NRC.

  1. NRC-P sends a notify message (wscIsActive=FALSE, mateAddr, matePort) over the global channel to currently active VSR-NRC to request transition to standby role.
  2. The currently active VSR-NRC shuts down the cproto sync channel to its mate and prepares the mate copy DBs to accept the updates from its mate VSR-NRC.
  3. The currently active VSR-NRC sends to NRC-P a notify reply message (notifyReply=TRUE) to accept the standby role requested.
  4. NRC-P then follows the steps in Initial establishment of active/standby VSR-NRC roles to transition the currently standby VSR-NRC to active role.
