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

  1. Stop the services and perform service migration.
  2. After the service is migrated, collect fault information by referring to Fault Information Collection and contact technical support.
