Troubleshooting
Problem
A 'Sensor GPT Status has transitioned from normal to non-critical state' error may be logged at every restart or power-on, but the equipment has no internal hard drives and the error persists after isolating the compute node from SAN (if present) or any other possible boot source. (where GPT = GUID Partition Table, SAN = Storage Area Network, SAS = Serial Attached SCSI, UEFI = Unified Extensible Firmware Interface)

Symptom
A 'Sensor GPT Status has transitioned from normal to non-critical state' error may be logged at every restart or power-on, but the equipment has no internal hard drives and the error persists after isolating the compute node from SAN (if present) or any other possible boot source.
(where GPT = GUID Partition Table, SAN = Storage Area Network, SAS = Serial Attached SCSI, UEFI = Unified Extensible Firmware Interface)Affected configurations
The system may be any of the following IBM servers:
- Flex System x240 Compute Node, type 2588, any model
- Flex System x240 Compute Node, type 7162, any model
This tip is not software specific.
This tip is not option specific.
The following system BIOS/uEFI level(s) are affected: 1.50The 18.00.00.00 firmware for the LSI2004 is affected.
Workaround
To prevent the alert messages on each restart, disable the on-board SAS controller at the UEFI:
System Settings --> Devices and I/O Ports --> Enable / Disable on-board device(s) --> SAS ControllerAdditional information
By disabling the on-board SAS, the UEFI firmware will not receive any reports on internal volumes.
It has been observed that the LSI2004 internal SAS adapter may report a non-existent volume to the UEFI during the boot sequence, causing the UEFI to either report only or try to fix and report, depending on the DiskGPTRecovery parameter being set to 'None' or 'Automatic' in UEFI settings (refer to tip H21166).
