IBM Flex System p24L Installation And Service Manual page 99

v For a Linux operating system, collect the dump from the /var/log/dump directory.
v For an IBM Flex System p24L 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.
See "System-board connectors" on page 12 for component locations.
Notes:
1. Location codes do not indicate the location of the compute node within the IBM Flex System
Enterprise Chassis. The codes identify components of the compute node only.
2. For checkpoints with no associated location code, see "Light path diagnostics" on page 446 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 7, see the "Checkout procedure" on page 414.

Components
Un location codes are for enclosure and VPD locations.
Un = Utttt.mmm.sssssss
tttt = system machine type
mmm = system model number
sssssss = system serial number
