4. Have the same address jumpers/terminators/cabling
5. Have the same software versions and levels
6. Have the same diagnostics code (version)
7. Have the same configuration options set in the system
8. Have the same setup for the operation system control files
Comparing the configuration and software setup between “working” and
“non-working” systems will often lead to problem resolution.
Calling IBM for service
When you call for service, have as much of the following information available as
possible:
v Machine type and model
v Microprocessor and hard disk drive upgrades
v Failure symptoms
– Does the server fail the diagnostic programs? If so, what are the error codes?
– What occurs? When? Where?
– Is the failure repeatable?
– Has the current server configuration ever worked?
– What changes, if any, were made before it failed?
– Is this the original reported failure, or has this failure been reported before?
v Diagnostic program type and version level
v Hardware configuration (print screen of the system summary)
v UEFI code level
v Operating-system type and version 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 level
v Memory amount, type, and configuration
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
v Operating-system control-file setup
