v Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable symptoms.
These tables are in the online information and the Problem Determination and Service Guide for your
compute node.
v Dump data collection
In some circumstances, an error might require a dump to show more data. The Integrated
Virtualization Manager (IVM) or Hardware Management Console (HMC) sets up a dump area. Specific
IVM or HMC information is included as part of the information that can optionally be sent to IBM
support for analysis.
See "Collecting dump data" on page 109 for more information.
v Stand-alone diagnostics
The AIX-based stand-alone diagnostics CD is in the ship package and is also available from the IBM
Web site. Boot the diagnostics from a CD drive or from an AIX network installation manager (NIM)
server if the compute node cannot boot to an operating system, no matter which operating system is
installed.
Functions provided by the stand-alone diagnostics include:
– Analysis of errors reported by the platform, such as microprocessor and memory errors
– Testing of resources, such as I/O adapters and devices
– Service aids, such as firmware update, format disk, and Raid Manager
v Diagnostic utilities for the AIX operating system
Run AIX concurrent diagnostics if AIX is functioning instead of the stand-alone diagnostics. Functions
provided by disk-based AIX diagnostics include:
– Automatic error log analysis
– Analysis of errors reported by the platform, such as microprocessor and memory errors
– Testing of resources, such as I/O adapters and devices
– Service aids, such as firmware update, format disk, and Raid Manager
v Diagnostic utilities for Linux operating systems
Linux 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 the Linux
operating system, a set of tools that aids the installation of the Linux operating system on IBM
compute nodes that are based on IBM POWER7 Architecture technologies. You can also use the tools to
update the IBM Flex System p260 Compute Node or IBM Flex System p460 Compute Node 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.
See "Installing service and productivity tools for Linux" on page 31 for more information.
v Diagnostic utilities for other operating systems
You can use the stand-alone diagnostics CD to perform diagnostics on the IBM Flex System p260
Compute Node or IBM Flex System p460 Compute Node, no matter which operating system is loaded
on the compute node. 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.
