Host TPM attestation alarm | Fresh Installed vCenter 8

[Sofa_]

Hi all,

i have a fresh installed vCenter Installation what shows a triggered alarm: Host TPM attestation alarm but no details.

Can anybody tell me where i find details what the problem is?

Thanks

You need to figure out how to enable the TPM 2.0 module in your system BIOS. What type of hardware are you using? We have to do this with our Dell equipment when we first deploy it.

Hi there,

It's a Dell PowerEdge, the TPM is Enabled.

But is it enabled the way VMware wants it done? The default settings were not good enough for me. 

Look at this post

Hi,

From vCenter inventory try below procedure:

1. Enter maitanance mode

2. Disconnect host

3. Connect host

5. Exit maitanance mode

6. go to cluser > monitor > security to see that now attestation has status "passed"

7. [Optionally] check in bios > security menu that TXT has also status "on"

Thanks for you Reply but i can't see any usable hint to get me forward.

Is there no message vmware log where the problem is?

It is solved. You've click to Datacenter -> Security at this Point you've the exact problem vcenter is expecting.

in that case, Secure Boot - Disabled was the problem.
