Red Hat Summit5.7. Device-Mapper-Einträge mit dem dmsetup-Befehl ermitteln.
Mit Hilfe des Befehls
dmsetup können Sie herausfinden, welche Device-Mapper-Einträge zu welchen multipathed-Geräten passen.
Der folgende Befehl zeigt alle Device-Mapper-Geräte und ihre Major- und Minor- Nummern an. Die Minor-Nummern bestimmen den Namen des dm-Geräts. So entspricht eine Minor-Nummer 3 beispielsweise dem multipathed-Gerät
/dev/dm-3.
