Restore Using MKSYSB and NIM

  1. These steps differ from what power platform firmware the system is on.
  2. Bring system down, and boot up and select SMS mode on startup usually by pressing 1 or F1.
  3. If this server is managed by NIM, configure a remote IPL device.
  4. If not, manually select the boot device and continue with the restore.
