Because of the variety of hardware and software combinations
that can encounter, use the following information to assist you in
problem determination.
If possible, have this information available when requesting assistance
from Lenovo.
The model name and serial number are located on the ID label on
the front of the server as shown in the following illustration.
Note: The illustrations in this document might differ slightly from
your hardware.

- Microprocessor or hard disk drive upgrades
- Failure symptom
- Does the server fail the diagnostic tests?
- What occurs? When? Where?
- Does the failure occur on a single server or on multiple servers?
- Is the failure repeatable?

You can solve some problems by comparing the configuration and
software setups between working and nonworking servers. When you compare
servers to each other for diagnostic purposes, consider them identical
only if all the following factors are exactly the same in all the
servers:
- Machine type and model
- UEFI firmware level
- IMM firmware level
- Adapters and attachments, in the same locations
- Address jumpers, terminators, and cabling
- Software versions and levels
- Diagnostic program type and version level
- Configuration option settings
- Operating-system control-file setup
