Is a requirement that the devices collected from the poller are the same than the mirror.
What happen when we discover a poller?
- The first time we discover a poller, all the nodes are copied into the master. But once they have being copied, in the synchronisations the node configuration will be send from the master to the poller.
- The server will be set up as a poller, so we are not gonna be able to edit the nodes from the poller.
What happen when we discover a mirror?
- The first time we discover a mirror, it needs to be empty (Except for localhost). This is because, all nodes needs to be copied from the poller that is being mirroring.
- The nodes will be sent to the mirror, the mirror will start polling those devices, at the same time that the poller.
- But the data it won't be synchronised, unless the poller is disabled/down.
- The server will be set up as a mirror, so we are not gonna be able to edit the nodes from the mirror.
- Every time we made a change into the poller nodes from the master, they will be replicated into the mirror.
What happen when we remove a poller?
We can update the role before remove the poller. If not, we are not going to be able to manage the nodes. We can do this manually by setting opha_role in conf/opCommon.json and restarting the server.
The mirror will became the poller.
