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.
- 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.
- 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.
- The currently active VSR-NRC sends to NRC-P a notify reply message
(notifyReply=TRUE) to accept the standby role requested.
- 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.
