6.
Install and turn on the blade server. If the problem remains, suspect the
following components in order:
a.
DIMM
b.
System-board and chassis assembly
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
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
Address cabling
v
Software versions and levels
v
Diagnostic program type and version level
v
Configuration option settings
v
Operating-system control-file setup
