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 Linux, a set of
tools that aids the installation of Linux on IBM servers with POWER
tools to update the PS703 or PS704 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.
v Diagnostic utilities for other operating systems
You can use the stand-alone diagnostics CD to perform diagnostics on the PS703 or PS704 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.
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 by operating system.
v For an AIX operating system, collect the dump from the /var/adm/platform directory.
v For a Linux operating system, collect the dump from the /var/log/dump directory.
v For a PS703 or PS704 blade server that is managed by the Integrated Virtualization Manager (IVM),
collect the dump using the Manage Dumps task in the IVM console.
Location codes
Location codes identify components of the blade server. Location codes are displayed with some error
codes to identify the blade server component that is causing the error.
See "System-board connectors" on page 9 for component locations.
Notes:
1. Location codes do not indicate the location of the blade server within the BladeCenter unit. The codes
identify components of the blade server only.
2. For checkpoints with no associated location code, see "Light path diagnostics" on page 210 to identify
the failing component when there is a hang condition.
3. For checkpoints with location codes, use the following table to identify the failing component when
there is a hang condition.
4. For 8-digit codes not listed in Table 6 on page 18, see the "Checkout procedure" on page 176.
