8. Remove or disconnect the following devices one at a time, if installed, until you
find the failure:
v
InfiniBand card
v
Hard disk drive
v
PCI-Express card
Reinstall, turn on, and reconfigure the blade server each time.
If the problem is solved when you remove the device from the blade server but the
problem recurs when you reinstall the same device, suspect the device; if the
problem recurs when you replace the device with a different one, suspect the
system board. Have a trained service technician replace the system board
assembly.
If you suspect a networking problem and the blade server passes all the system
tests, suspect the network switch.
Note: The problem may concern the network and be external to the system.
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 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
Firmware level
v Adapters and attachments, in the same locations
v
Address jumpers, terminators, and cabling
v Software versions and levels
v
Configuration option settings
