If the problem is solved when you remove an I/O expansion option from the blade server but the
problem recurs when you reinstall the same expansion option, suspect the expansion option; if the
problem recurs when you replace the expansion option with a different one, suspect the System-board
and chassis assembly.
If you suspect a networking problem and the blade server passes all the system tests, suspect a network
cabling problem that is external to the system.
Calling IBM for service
Call IBM for service after you collect as much as possible of the following information.
Before calling for service, collect as much as possible of the following available information:
v
Machine type and model
v
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
Firmware level
v
Operating-system type and version level
v
Advanced Management Module service data. See Advanced Management Module Messages Guide.
v
SNAP data. See Blade server Data Collection Guide
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
Firmware level
v
Adapters and attachments, in the same locations
v
Software versions and levels
v
Diagnostic program type and version level
v
Configuration option settings
v
Operating-system control-file setup
