Service action
1. If the NVMe Flash adapter has an amber LED that is flashing or is on solid,
replace the adapter. Go to "8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or
8335-GTX locations" on page 25 to identify the physical location and removal
and replacement procedure.
Important: Before you remove an NVMe Flash adapter, ensure that you back up
all data on the adapter or the array that contains the adapter. After you replace
the adapter, restore the data.
2. If the system was recently installed, moved, serviced, or upgraded, verify that the
NVMe Flash adapter is seated and installed properly.
3. Verify that the NVMe Flash adapter is compatible with the system.
4. Verify that the most recent firmware is installed on the system. Otherwise, install
the most recent firmware if it is not already installed.
5. Replace the NVMe Flash adapter. Go to "8335-GTC, 8335-GTG, 8335-GTH,
8335-GTW, or 8335-GTX locations" on page 25 to identify the physical location
and removal and replacement procedure.
Important: Before you remove an NVMe Flash adapter, ensure that you back up
all data on the adapter or the array that contains the adapter. After you replace
