LPAR example

In this example, a Linux instance running on an LPAR is dumped to a DASD device. The dump is initiated from an HMC or SE.

1. 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.
2. Select the LPAR for which you want to initiate the dump.
3. In the Tasks area, click Stop all processors (which is located in the Recovery section) to stop all CPUs. Confirm when you are prompted to do so.
4. In the Tasks area, click Load to display the Load panel.
   Figure 1 shows an example of an HMC with a selected hardware system and LPAR. The Load and Stop all processors tasks can be seen in the Tasks area.

   

5. Select Load type Standard load.
   Note: You must not select the Clear the main memory on this partition before loading it check box. Clearing the memory destroys the dump content.
6. Select the Store status check box.
7. Type the device number of the dump device into the Load address field.
   To IPL from a subchannel set other than 0, specify five digits: The subchannel set ID followed by the device number, for example 1E711. Figure 2 shows a Load panel with all entries and selections required to start the dump process for a DASD or tape dump device.

   

8. Click OK to start the dump process.
9. Wait until the dump process completes. Click the Operating System Messages icon for progress and error information.
