Resolving an NVMe Flash adapter problem

Learn about the possible problems and service actions that you can perform to resolve a Non-Volatile
Memory Express (NVMe) Flash adapter problem.
If you suspect a problem with a PCIe3 1.92 TB CAPI NVMe Flash accelerator adapter (FC EJ1K; CCIN
58CD), see PCIe3 1.92 TB CAPI NVMe Flash Accelerator Adapter (FC EJ1K; CCIN 58CD).
If you suspect a problem with an NVMe Flash adapter, use the following table to determine the service
action to perform.
Note: To determine the location of the NVMe Flash adapter, see "Identifying the location of the NVMe
Flash adapter" on page 23.

Service action
1. If the system was recently installed, moved, serviced,
or upgraded, verify that the GPU is seated properly.
2. Inspect the GPU and verify that it is not physically
damaged.
3. If the GPU is still not working, replace the following
items, one at a time, until the problem is resolved:
