This DisplayString reports the ClusterXL operating mode of this member, per 'Working mode,' such as High Availability (active/standby) versus Load Sharing. This setting fundamentally changes how traffic is expected to be distributed across cluster members, so it's the first thing an admin checks when trying to understand whether both members should be seeing traffic simultaneously or only one. If this reports Load Sharing when the admin's design assumed active/standby, that mismatch would explain unexpected traffic patterns across the two members.
