En redundansrelation kan ses som en partnerlänk mellan två servrar.
När servern upptäcker att den inte är synkroniserad med partnerservern för en redundansrelation vid en angiven tid uttryckt i minuter.
Situationen ändrar tillståndet för övervakaren till fel.
Kontrollera om partnerservern körs eller om kommunikation med lokal server är möjlig.
Kontrollera om du kan kommunicera med redundanspartnerservern med hjälp av ett Ping-kommando.
