Collecting dump data
A dump might be critical for fault isolation when the built-in First Failure Data
Capture (FFDC) mechanisms are not capturing sufficient fault data. Even when a
fault is identified, dump data can provide additional information that is useful in
problem determination.
All hardware state information is part of the dump if a hardware checkstop occurs.
When a checkstop occurs, the service processor attempts to dump data that is
necessary to analyze the error from appropriate parts of the system.
Note: If you power off the blade through the management module while the
service processor is performing a dump, platform dump data is lost.
You might be asked to retrieve a dump to send it to IBM Support for analysis. The
location of the dump data varies per operating system platform.
Functions provided by the stand-alone diagnostics include:
– Analysis of errors reported by platform, such as microprocessor and memory
– Testing of resources, such as I/O adapters and devices
– Service aids, such as firmware update, format disk, and Raid Manager
Run AIX concurrent diagnostics if AIX is functioning instead of the stand-alone
diagnostics. Functions provided by disk-based AIX diagnostic include:
– Automatic error log analysis
– Analysis of errors reported by platform, such as microprocessor and memory
– Testing of resources, such as I/O adapters and devices
– Service aids, such as firmware update, format disk, and Raid Manager
Linux on POWER service and productivity tools include hardware diagnostic
aids and productivity tools, and installation aids. The installation aids are
provided in the IBM Installation Toolkit for Linux on POWER, a set of tools that
aids the installation of Linux on IBM servers with POWER architecture. You can
also use the tools to update the JS22 blade server firmware.
Diagnostic utilities for the Linux operating system are available from IBM at
https://www14.software.ibm.com/webapp/set2/sas/f/lopdiags/home.html.
You can use the stand-alone Diagnostics CD to perform diagnostics on the JS22
blade server, no matter which operating system is loaded on the blade server.
However, other supported operating systems might have diagnostic tools that
are available through the operating system. See the documentation for your
operating system for more information.
