TPM_E_INVALID_FAMILY
Locate the first producer
TPM_E_INVALID_FAMILY (0x80280037) belongs to TPM 1.2 nonvolatile-storage policy. This result means a delegation command refers to a family identifier that is absent, stale or not valid for the requested TPM 1.2 operation.
The first producer to identify is the TPM 1.2 NV permission and lifecycle checks. TPM 1.2 NV indices combine permissions, authorization mode, locality masks and lock semantics. Two indices of the same size can behave differently because those attributes were fixed when each index was defined.
Data to retain
| Question | Evidence |
|---|---|
| What exact state was rejected? | a delegation command refers to a family identifier that is absent, stale or not valid for the requested TPM 1.2 operation |
| Which layer owns the result? | The TPM 1.2 NV permission and lifecycle checks. |
| What must be correlated? | family ID, family verification count, delegation row, owner state, command ordinal, and the context in which the family was created |
| Controlled comparison | enumerate current delegation-family state and compare a freshly created test family rather than reusing a persisted numeric ID |
Separate caller data from platform state. The caller data includes the command, structures, lengths, handles and flags; platform state includes TPM generation, provisioning, locality, lockout, resource inventory, firmware and the TBS service lifecycle. This result is actionable only after the rejected side is identified.
Verification sequence
Use the following verification sequence:
- Capture the unmodified failing input and
0x80280037. - Enumerate current delegation-family state and compare a freshly created test family rather than reusing a persisted numeric id.
- Compare the first divergent field or state transition.
- Repeat the operation only after restoring the same baseline, with a bounded retry policy where the specification permits retry.
Codes that answer different questions
| Other code | Why a different remedy follows |
|---|---|
TPM_E_NO_NV_PERMISSION | The permission to manipulate the NV storage is not available. |
TPM_E_REQUIRES_SIGN | The operation requires a signed command. |
TPM_E_KEY_NOTSUPPORTED | Wrong operation to load an NV key. |
TPM_E_FAMILYCOUNT identifies a verification-count mismatch for an otherwise selected family. The difference determines whether to change serialization, authorization, resource lifetime, firmware/PPI state, command policy or only retry timing.
Exit condition for the incident
Correct the original boundary by choosing this direction: refresh the family reference and rebuild dependent delegation blobs after family deletion, reset or ownership change. Do not undefine a production NV index until its public attributes and authorization policy have been recorded. NV policy is established at definition time, and destructive recreation can remove counters, certificates or provisioning state.
