You can also check the replication status of all PSCs with the vcdrepadmin – f showpartners command. Each PSC must have 2 replication partners. In our example, we therefore create the agreement between PSC37 and PSC35, so that in the event of a PSC36 failure, we always have replication with another partner in the field. If PSC2 dies, replication continues. If you connect PSC1 to PSC4, the full ring is created.
