Calling IBM for service
See Appendix A, “Getting help and technical assistance,” on page 63 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, model, and serial number
v
Management-module service data information (see the documentation for your
BladeCenter unit management module).
v Failure symptoms
– Does the BMC error log report any errors? If so, what are the errors?
– Does the blade workstation fail the diagnostic programs? If so, what are the
error codes?
– What occurs? When? Where?
– Is the failure repeatable?
– Has the current BladeCenter 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
Hardware configuration (print screen of the system summary)
v CPOS code level
v
Operating-system type and version level on the host blade server
v Host blade server machine type and serial number
v
Host blade server BIOS code level
v Host blade server
You can solve some problems by comparing the configuration and software setups
between working and nonworking workstations. When you compare workstations to
each other for diagnostic purposes, consider them identical only if all the following
factors are exactly the same in all the blade workstations:
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
