These days I had to troubleshoot a problem in a vCenter environment. A few VMs shown with absolute path to vmx file in vCenter inventory. Normally this occurs when a ESXi boots with no connection to its previous mounted storage volumes. VMs located on these volumes are shown like this in inventory. But this wasn’t the case here: VMs were running and no host was […]
