Collecting Dump Data; Location Codes - IBM Flex System p260 Installation And Service Manual

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.
About this task
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 compute node 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.
Procedure
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 an IBM Flex System p260 Compute Node or IBM Flex System p460 Compute Node that is
managed by the Integrated Virtualization Manager (IVM), collect the dump using the Manage Dumps
task in the IVM console.
v To collect a system dump by using the Hardware Management Console (HMC), complete these steps:
1. Perform a controlled shutdown of all partitions.
Note: A system dump will abnormally terminate any running partitions.
2. In the navigation area, open Systems Management.
3. Select the server and open it.
4. Select Serviceability > Manage Dumps > Action > Initiate System Dump. The dump is
automatically saved to the HMC. For details on how to copy, report, or delete a dump after you
have completed a dump, see Managing dumps.

Location codes

Location codes identify components of the compute node. Location codes are displayed with some error
codes to identify the compute node component that is causing the error.
