TPM Management - tpm_setactive
tpm_setactive − change TPM active states
tpm_setactive [OPTION]
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.
−h, −−help

-v, −−version
Display command version info.
-l, −−log [none|error|info|debug]
Set logging level.
-u, −−unicode
Use TSS UNICODE encoding for passwords to comply with applications using TSS popup boxes
-s, −−status
Report the status of flags regarding the TPM active states.
-a, −−active
Make the TPM active. Operation is persistent, requires phyiscal presence to authorize, and a reboot to take effect.
-i, −−inactive
Make the TPM inactive. Operation is persistent, requires phyiscal presence to authorize, and a reboot to take effect.
-t, −−temp
Makes the TPM inactive for the current boot cycle only.
-z, −−well-known
Authenticate using 20 bytes of zeros as owner password (the default TSS Well Known Secret), instead of prompting for an owner password.
