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

(%systemdrive%\cpqsystem\log\cpqstub.log).

Because the installation is silent, the installation is

terminated and cannot continue.
