Meaning
The monitored OS servers are available and are located in runtime and the status is "OK".
One server or multiple servers have a problem. The servers are still available for the clients.
If a server partner is switched off or has an error state and the second server partner also devel-
ops an error state, the second server partner initially remains available for the connected clients.
The second server partner only disconnects the clients if the first server partner is in an opera-
tional state again and has synchronized with the second server partner. This therefore ensures
that the clients can at least connect to this server pair, even if both server partners have a prob-
lem.
