			 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 phys-
     ical  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 pres-
     ence, 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 --sta-
     tus, --active, --inactive, and --temp options are	mutually  exclusive  and
     the last one on the command line will be carried out.

	    Make  the TPM inactive.   Operation is persistent, requires phyiscal
	    presence to authorize, and a reboot to take effect.

     -t, --temp

     -z, --well-known
