If the device is the only device on a bus, be sure the bus works by installing a different device on the
bus.
Restarting the server each time to determine if the device is working, move the device:
A.
To a PCIe slot on a different bus
B.
To the same slot in another working server of the same or similar design
If the board works in any of these slots, either the original slot is bad or the board was not properly seated.
Reinstall the board into the original slot to verify.
If you are testing a board (or a device that connects to a board):
A.
Test the board with all other boards removed.
B.
Test the server with only that board removed.
Clearing NVRAM can resolve various issues.
Verify that the PCIe device or graphics controller does not need additional power to operate. For more
information, see the device documentation.

Drive issue
Drives are failed
Action
Be sure no loose connections exist.
Check to see if an update is available for any of the following:
A.
RAID Controller firmware
B.
RAID driver
C.
Host bus adapter firmware
Be sure the drive or backplane is cabled properly.
Be sure the drive data cable is working by replacing it with a known functional cable.
Be sure drive blanks are installed properly when the server is operating. Drives may overheat and
cause sluggish response or drive failure.
Be sure the replacement drives within an array are the same size or larger.
Be sure the replacement drives within an array are the same drive type, such as SAS, SATA, or SSD.
Power cycle the server. If the drive shows up, check to see if the drive firmware needs to be updated.
