Dieser Modultyp wird verwendet, um Instanzen von Zeugen gespiegelter Microsoft SQL Server 2012-Datenbanken zu ermitteln. Das Modul stellt eine Verbindung zu SQL Server her und ermittelt alle Zeugen für gespiegelte Datenbanken zusammen mit ihren Eigenschaften.
Eine durch Trennzeichen getrennte Liste von Datenbankinstanzen, die von der Ermittlung ausgeschlossen werden sollten. Mit dem Platzhalter * können alle Instanzen ausgeschlossen werden.
