In the vSphere Web client an orphaned vSAN object was listed named:
From the vSphere Web Client you cannot manage orphaned vSAN objects . To check and fix orphaned vSAN objects, the Ruby vSphere Console (RVC) is needed. The ‘vsan.check_state’ command checks if VMs and Virtual SAN objects are valid and accessible.
After logging in the RVC (rvc email@example.com@localhost), execute the “vsan.check_state -r” command at the cluster level:
The “-r” parameter refreshes the VMX and registers the VMs.
After running the “vsan.check_state -r” command, the vSAN object is listed as VM back again in the vSphere Web Client.
