Perform a manual main storage dump

Use this procedure on the primary partition or on a system without logical partitions.

To place the data from the system's main storage to the load-source disk, perform the following procedure:
  1. If your system has logical partitions, try to power them off.
  2. Verify that there are no interactive jobs running.
    1. Select Manual mode.
    2. Use the Increment/Decrement buttons to display function 22 (main storage dump).
    3. Press Enter on the control panel.
  3. Is 0000 0000 displayed on the control panel for more than 30 seconds?
    • Yes: The multiple function input/output processor (IOP) or service processor is not responding to a request from the control panel. Go to the Report problems: Overview. This ends the procedure.
    • No: An attention SRC, A1xx 3022, is displayed, which indicates that function 22 has been selected.
  4. Reselect function 22, press Enter on the control panel, and wait for the dump to complete. When the dump is complete, the Main Storage Dump Occurred display is shown. The appearance of an A1D0 300x or A6Dx 3000 SRC on the Main Storage Dump Occurred display indicates a successful manual MSD.
  5. Go to the Report a main storage dump. This ends the procedure.
