Hi,

if you got an error TPM Attestation failed, Message: Internal failure.


Set the maintenance mode for the ESXi Host

, disconnect the host from the cluster and reconnect it.
Disconnect

PS D:\> Set-VMHost -VMHost myESXiHost.myDomain.org -State Disconnected

and reconnect

PS D:\> Set-VMHost -VMHost myESXiHost.myDomain.org -State Connected

Check the TPM attestation state by Powercli

PS D:\> (Get-View (Get-VMHost myESXiHost.myDomain.org)).Summary.TpmAttestation
