A primary instance can provide information about all the secondary
instances replicating from it. However, a secondary instance only knows
about the primary instance from which it is replicating. However, for
scenarios, where the primary instance is unavailable(e.g. regional outage),
a Getinstance request can be sent to any other member instance and this
field will list all the member instances participating in cross instance
replication.
