Using the Reset Button

Edit online

In AIX® 5.3 and subsequent releases, pressing the reset button always dumps to the primary dump device. This is also true for LPAR systems running AIX® 5.2.

Start a system dump with the Reset button by doing the following (this procedure works for all system configurations and will work in circumstances where other methods for starting a dump will not work):

  1. If your machine has a key mode switch, do one of the following:
    • Turn the key mode switch to the Service position.
    • Set Always Allow System Dump to true.
    • Press the Reset button.
  2. If your machine does not have a key mode switch, set Always Allow System Dump to true and press the Reset button.

Your system writes the dump information to the primary dump device.

Note: The procedure for using the reset button can vary, depending upon your hardware configuration.
