En redundansrelation kan ses som ett partnerskap mellan två servrar.
När servern upptäcker att den inte är tidssynkroniserad med partnerservern för en redundansrelation med viss tid i minuter.
Denna situation kommer att ändra tillståndet för övervakaren till fel.
Kontrollera om partnerservern körs eller om kommunikation med den lokala servern är möjlig.
Kontrollera om du kan kommunicera med partnerreservservern genom ping-kommandot.
