Pulling the Plug

• Pulling the plug is a last resort where the risk to other systems is high and there is no other safe option.

• You may have no choice!

• Use Magic SysRq S-U-B first if possible

• Data Preserved

  • Non-volatile data
  • Shadow data

• Data Lost

  • Cached data
  • Volatile data and machine state

• Risks

  • Self destruct - known to exist
