PowerFlex TPM 2.0: Device Detected, but a Connection Cannot be Established

Alarm in vCenter: 

For more information about Trusted Platform Module (TPM) version 2.0 in the vCenter 6.7 environment, see VMware documentation at vSphere Security

The ESXi vCenter queries the host BIOS to see if it has a TPM chip. If it does, an alarm sounds as it cannot communicate due to the chip being present and not enabled. This is cosmetic in nature and can be ignored. 

The PowerFlex personality module is TPM disabled by default. The feature is not properly supported but is expected to be coming in future releases. 

Option 1:
Disable TPM and safely ignore this message. Engineering is investigating the best way to suppress this message in the future but until that time, disable TPM.  

Option 2:
Using the command line to disable TPM safely using RacADM:
(Scripted notes after # are comments and not part of the command.)

racadm -r <ip addr> -u root -p XXXXX get Bios.SysSecurity.TpmSecurity              # command to check effective value
 
racadm -r <ip addr> -u root -p XXXXX set Bios.SysSecurity.TpmSecurity Off          # command to disable it.

racadm -r <ip addr> -u root -p XXXXX get Bios.SysSecurity.TpmSecurity              # command to check the pending value

racadm -r <ip addr> -u root -p XXXXX jobqueue create BIOS.Setup.1-1 -r pwrcycle    # command soft-reboots the host immediately and applies
