Calling Ibm For Service - IBM BladeCenter JS21 Types 8844 Service Manual

Calling IBM for service

See Appendix A, "Getting help and technical assistance," on page 171 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
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 blade server. When you compare blade servers to
each other for diagnostic purposes, consider them identical only if all the following
factors are exactly the same in all of the blade servers:
v Machine type and model
v BIOS 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
v Operating-system control-file setup

– Is this the original reported failure, or has this failure been reported before?
