Enabling and disabling a Virtual Trusted Platform Module on a logical partition

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.

To enable a VTPM, ensure that an AIX®, Linux or a Virtual I/O Server (VIOS) logical partition is in the Not activated state.

The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.

For information about enabling VTPM on a logical partition when the HMC is at version 8.7.0, or later, see Changing advanced partition settings.

To enable a VTPM on a logical partition, complete the following steps:

  1. In the navigation pane, open Systems Management > Servers, and click the system on which the logical partition is located.
  2. Select the logical partition in the work pane.
  3. From the Tasks menu, click Properties.
    • If the Virtual Trusted Platform Module check box is selected, the logical partition is enabled for VTPM.
    • If the Virtual Trusted Platform Module check box is not selected, the logical partition is not enabled for VTPM. To enable a VTPM on the logical partition, select the Virtual Trusted Platform Module check box.
  4. Click OK.
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.
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.
