Calling IBM for service
See Appendix B, “Getting help and technical assistance,” on page 111 for
information about 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 blade 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 BIOS 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 blade servers:
v
Machine type and model
v
All relevant firmware levels
v
Adapters and attachments, in the same locations
v Address jumpers, terminators, and cabling
v
Software versions and levels
v Configuration option settings
v
Operating system control file setup
