LPAR example

You can initiate a kdump process on an LPAR from an HMC (Hardware Management Console) or SE (Support Element).

Before you begin

Your Linux® instance must be set up for kdump as described in Setting up kdump.

The following description refers to an HMC, but the steps also apply to an SE.

In the navigation pane of the HMC, expand Systems Management and select the hardware system you want to work with.
A table of LPARs is displayed in the content area.
Select the LPAR for which you want to initiate the dump.
In the Tasks area, click PSW restart, which is located in the Recovery section. This initiates the dump process.
Figure 1 shows an example of an HMC with a selected hardware system and LPAR. The PSW restart task can be seen in the Tasks area.

Wait until the dump process completes. Click the Operating System Messages icon for progress and error information.

kdump automatically collects the dump and reboots Linux.
