The Trusted Platform Module (TPM) system integrity check may return an invalid status. As a result of this issue, you may encounter one or more of the following symptoms: -- While the system boots to BIG-IP 14.1.0, you observe an error message that appears similar to the following example: tpm-status-check: System Integrity Status: Invalid -- After rebooting the system to different volumes, you continue to observe the previous error message.
The BIG-IP system reports an invalid TPM status and TPM is non-functional.
This issue occurs when the following condition is met: You reboot a system running either BIG-IP 13.1.x or 14.0.0 (including their point releases) to BIG-IP 14.1.0.
To recover from this issue, you must delete the grub configuration file and reboot the system twice for an automatic repair to occur. To do so, perform the following procedure: Impact of workaround: The system will not be available while performing multiple reboots. F5 recommends that you perform this procedure during an appropriate maintenance window. 1. Log in to the command line of the affected system. 2. Mount the boot partition by typing the following command: mkdir -p /mnt/boot; mount /dev/mapper/$(ls /dev/mapper | grep boot) /mnt/boot 3. Delete the grub.multiboot.cfg file by typing the following command: rm -f /mnt/boot/grub2/grub.multiboot.cfg 4. Reboot the system by typing the following command: reboot Note: The system software fixes the grub.multiboot.cfg file automatically upon booting. 5. When the system has completed booting, log in to the command line and reboot the system again by typing the following command: reboot This final step properly boots the system with TPM enabled.
Rebooting a system no longer returns the TPM error.
