Checking the Server Pair Status
The System page is the first page that opens when administering a pair of servers. The System page displays
the roles of the servers, active or passive, the actions that the servers are currently performing, and how well
the system is coping with file and registry replication.
The system status in the central grid for each server indicates procedures being executed. Table 6-1 lists each
status with a description.
The central grid also displays queue delays for each server. Queues show the time a specific piece of
information resides in the passive server (safe) and active server (unsafe) queues respectively before moving
to the passive server (safe) queue or committed to disk. Above the data grid, the connection status and speed
are graphically represented. The Server Pair panel graphically displays the file and registry synchronization
status with icons described in Table 6-2.
Table 6-1. System Status
Status Description
Not Replicating The file and registry replication has stopped and all protected applications also could be
stopped.
Stopping Replication The file and registry replication is in the process of stopping and all protected applications also
could be closing down.
Replicating File and registry changes on the active server are being intercepted and replicated to the passive
server and protected applications are being monitored (This is the normal status).
Starting Replication The replication process is in the process of starting and protected applications are being started.
Shutting Down The vCenter Server Heartbeat file and registry interceptor has stopped. All protected
applications also could have stopped. The Neverfail Server R2 service is stopping.
Preparing to Switch The system is performing ancillary operations prior to a switchover such as flushing the queues.
Switching The system is in the process of performing a switchover.
