Hi,

I recently upgraded to 7.3.1 with internal boot and wanted to move from USB license to TPM. I installed a physical TMP 2.0 module in a Supermicro X13SAE board and enabled it in the BIOS. Unraid is able to see the TPM device via the command line but unable to see it via the "Registration" page. Not sure if this is tied into another issue I am having with Unraid Connect and potential dependency (created topic for this issue in Connect Plugin support section https://forums.unraid.net/topic/199414-unable-to-sign-into-unraid-connect-731/).

Here is the output from the command line (redacted some information as I don't know what is sensitive and what is not:

root@Unraid:~# dmesg | grep -i tpm

[ 0.000000] efi: ACPI=

[ 0.019596] ACPI: TPM2 (v04 SUPERM SMCI--MB)

[ 0.019637] ACPI: Reserving TPM2 table memory at [mem]

[ 15.843486] tpm_tis MSFT0101:00: 2.0 TPM (device-id , rev-id)

root@Unraid:~# cat /sys/class/tpm/tpm0/tpm_version_major

2

root@Unraid:~#

Please post the diagnostics

TPM devie is being foudn but is failign to create a key

Jun 12 15:33:23 Unraid emhttpd: ECC CreatePrimary failed on /dev/tpmrm0: 0x9A2 - falling back to RSA-2048

Jun 12 15:33:23 Unraid emhttpd: CreatePrimary failed on /dev/tpmrm0 (both templates tried): 0x9A2

Jun 12 15:33:23 Unraid emhttpd: No usable public area obtained from /dev/tpmrm0

Look for a BIOS update, also any option to "clear" the TPM device in the BIOS, then try again.

This was it!

Went into the BIOS, Trusted Platform Section, Pending Operation and set to "TPM Clear". Save and Reset.

Server Booted and TPM now shows up properly on Registration page with a TPM GUID.

Move to TMP completed successfully after reboot!
