Dell VxRail: Przydatne polecenia esxcli dotyczące sieci VSAN i kondycji obiektów
Summary: Ten artykuł zawiera polecenia umożliwiające przeprowadzenie podstawowej kontroli poprawności działania wirtualnej sieci pamięci masowej (VSAN). Może to również pomóc w rozwiązywaniu problemów na poziomie obiektu z sesji SSH hosta ESXi. Jest to przydatne, gdy vCenter jest w trybie offline lub gdy używane są usługi Secure Remote Services w celu lepszego rozwiązywania problemów. ...
