TPM scenarios
The following table discusses the TPM detection scenarios that you might encounter.
Scenario
Result
If the TPM is detected and enabled, the
installation is not silent, and a system ROM must
be updated.
A pop-up warning message appears. After OK is
selected, you can continue. The installation is not
canceled.
If the TPM is detected and enabled, the
installation is silent, the /tpmbypass switch is not
given, and any firmware updated must be
applied to the server.
No pop-up warning appears. A new log file is
generated
(%systemdrive%\cpqsystem\log\cpqstub.log).
Because the installation is silent, the installation is
terminated and cannot continue.
If the TPM is detected and enabled with Option
ROM Measuring, the installation is not silent, and
a system ROM must be updated.
A pop-up warning message appears. After OK is
selected, you can continue. The installation is not
canceled.
If the TPM is detected and enabled with Option
ROM Measuring, the installation is silent; the
/tpmbypass switch is not given, and any firmware
updated must be applied to the server.
No pop-up warning appears. A new log file is
generated
(%systemdrive%\cpqsystem\log\cpqstub.log).
Because the installation is silent, the installation is
terminated and cannot continue.
If the TPM is detected and enabled, the
installation is silent, and the /tpmbypass switch is
supplied.
The installation occurs.
Other scenarios do not affect the normal installation procedure.
