Resolving a GPU, PCIe adapter, or device problem

Learn how to access log files, information to identify types of events, and a list of potential problems and
service actions.
1. Are all of the adapters in the system missing or failed?
If Then
Yes: Replace the system backplane.
v If your system is an 8335-GCA or 8335-GTA, go to "8335-GCA and 8335-GTA locations"
v If your system is an 8335-GTB, go to "8335-GTB locations" on page 121 to identify the
v If your system is an 8348-21C, go to "8348-21C locations" on page 133 to identify the
No: Continue with the next step.
2. To identify the correct service procedure to perform by using operating system log information,
complete the following steps:
a. Log in as the root user.
b. At the command prompt, type dmesg and press Enter.
3. Scan the operating system logs for the first occurrence of keywords, such as fail, failure, or failed.
When you find a keyword that accompanies one or more of the resource names in the following table,
a service action is required. Use the following table to determine the service procedure to perform for
your type of problem.
