Issue/Introduction

When attempting to upgrade an ESXi host via vCenter, you may see messages similar to the following:

vCenter CLI:

/var/log/vmware/vmware-updatemgr/vum-server/vmware-updatemgr.log

####-##-##T##:###:##.###Z info vmware-vum-server[10875] [Originator@6876 sub=HostUpgradeScanner] [scannerImpl 1757] (vmodl.LocalizableMessage) [

-->       key = "com.vmware.vcIntegrity.HostUpgrade.UnsupportedTPMVersion",
-->       arg = <unset>,

--> ]

 

vCenter GUI:

Environment

VMware vCenter 7.x
VMware vCenter 8.x
VMware ESXi 7.x
VMware ESXi 8.x

Cause

A TPM version 1.2 device has been detected on the ESXi host, which is no longer compatible with ESXi 8.x, as TPM version 1.2 support has been deprecated.

Resolution

Engage with the hardware OEM(s) to see if you can upgrade the BIOS/TPM firmware all affected hosts to a supported TPM version. (2.0 or higher)
