It is possible for ESXi to not boot properly with errors such as:
SINIT Authenticated Code Module detected an intel Trusted Execution Technology(TXT) problem at boot.
These are caused due to TPM module. Clearing TPM module or resetting (Restarting) iDRAC does not seems to help. In such cases we need to do a cold reboot (Full poweroff and then after waiting sometime power on) of the server to solve the issue.
