What Do I Do If the GPU Is Disconnected or the Graphics Card Can't Be found, or rev ff Is Displayed After lspci | grep -i nvidia Is Executed?
Possible Causes
The health check failed so the GPU driver would not use or trust its content (some content is not used).
Impact
The ECC-related non-volatile data records may be affected. As a result, GPU memory pages that should have been retired are still in use.
Solution
- Stop the services and perform service migration.
- After the service is migrated, collect fault information by referring to Fault Information Collection and contact technical support.
