TPM Management - tpm_setactive
NAME
tpm_setactive - change TPM active states
SYNOPSIS
tpm_setactive [OPTION]
DESCRIPTION
tpm_setactive
reports the status of the TPM’s flags regarding the
active state of the TPM. This is the default behavior and
also accessible via the --status option. Requesting a
report of this status prompts for the owner password. The
--active option changes the TPM to the active state
(via the TPM_PhysicalSetDeactivated API). This operation
requires evidence of physical presence, is persistent and
requires a reboot to take effect. The --inactive
option (via the TPM_PhysicalSetDeactivated API) changes the
TPM to the inactive state. This operation requires evidence
of physical presence, is persistent and requires a reboot to
take effect. An inactive TPM is essentially off but still
allows for a tpm_takeownership to occur. The --temp
option causes deactivation (via the TPM_SetTempDeactivated
API) to happen immediately but only endure for the current
boot cycle. The --status, --active,
--inactive, and --temp options are mutually
exclusive and the last one on the command line will be
carried out.
