v Hardware configuration (print screen of the system summary)
v UEFI firmware level
v IMM firmware level

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:
v Machine type and model
v UEFI firmware level
v IMM firmware level
v Adapters and attachments, in the same locations
v Address jumpers, terminators, and cabling
v Software versions and levels
v Diagnostic program type and version level
v Configuration option settings
Model number
and serial number
