You can view the replica list of a partition from any view in NDS Manager.
From either the Tree View or the list of Partitions and Servers, select a partition.
The servers which contain replicas of the chosen partition are shown in the replica pane to the right of the browser.
To examine all of the servers holding replicas of a chosen partition and to verify that each server has a similar view of the partition's replica list (or replica ring), you must Check Partition Continuity ('walk the replica ring' of a partition).
