You can enable a Virtual Trusted Platform Module (VTPM)
on a logical partition by using the Hardware Management Console (HMC), after the logical
partition is created.
Before you begin
To enable a VTPM, ensure that an AIX®, Linux® or a Virtual I/O Server (VIOS) logical partition is in the Not activated
state.
About this task
For information about enabling VTPM on a logical partition, see Changing
advanced partition settings.
Results
If you dynamically enable a VTPM on a logical partition, the
VTPM function is activated only at the next logical partition activation.
However, disabling a VTPM takes effect immediately.
What to do next
To dynamically disable a VTPM, log on to the AIX, Linux or VIOS logical partition
and disable the Trusted Computing Services daemon (tcsd) by using
the stopsrc command. When the tcsd software
is stopped, the device must be removed from the AIX logical
partition by using the rmdev command. After the
device is successfully deleted from the AIX logical
partition, use the HMC to
clear the VTPM check box from the properties of the partition. This
completely removes the device and deletes all stored data that is
associated with the VTPM.
