Problem
System unable to find GPU
GPU stops working suddenly
Other problems
Service action
1. Verify that the GPU is properly seated in a
compatible slot.
2. Install the GPU in a different compatible slot.
3. Verify that the drivers for the GPU are installed.
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. Restart the system.
6. If the GPU is still missing, replace the following
items, one at a time, until the problem is resolved:
Note: Go to "8335-GCA and 8335-GTA locations" on
page 111 to identify the physical location and the
removal and replacement procedure.
a. GPU
b. System processor modules
c. System backplane
1. If the system was recently installed, moved, serviced,
or upgraded, verify that the GPU is seated properly
and all associated cables are connected correctly.
2. Inspect the PCIe socket and verify that there is no
dirt or debris in the socket.
3. Inspect the card and verify that it is not physically
damaged.
4. Verify that all cables are properly seated and are not
physically damaged. If you recently added one or
more new adapters, remove them and then test to
determine whether the failing adapter is functioning
properly again. If the graphics adapter is functioning
again, review the IBM support tips to confirm that
there are no PCI address, driver, or firmware
conflicts. Then, reinstall the new adapters again one
at a time until all adapters function properly.
5. If the GPU is still not working, replace the following
items, one at a time, until the problem is resolved:
Note: Go to "8335-GCA and 8335-GTA locations" on
page 111 to identify the physical location and the
removal and replacement procedure.
a. GPU
b. System processor modules
c. System backplane
