Removing disk units that have device parity protection for System i while powered off

Here are the detailed steps for removing disk units that have device parity protection for your system while your system is powered off.

  1. Press F3 repeatedly to exit System Service Tools and return to the main menu.
  2. Vary off any integrated servers that are installed on the system.
    1. Go to the Work with Configuration Status display by entering WRKCFGSTS at any command line. Press F4.
    2. At the Work with Configuration Status display, enter *NWS at the Type field and press Enter two times.
    3. At the Work with Configuration Status display, select the Vary off option in the Opt column next to the integrated server and press Enter.
    4. Press F12 to return to the Main Menu.
  3. Power off the system unit.

  4. Attention: If possible, use a wrist strap to prevent electrostatic discharge from damaging your hardware. If you do not have a wrist strap, touch a metal surface of the system or expansion unit before installing or replacing hardware.
    If you received the 2209 Disposable Wrist Strap, follow these steps:
    1. Attach the disposable wrist strap.
    2. When you unroll the strap, remove the liner from the copper foil at the end.
    3. Attach the adhesive part of the copper foil to an exposed, unpainted metal surface on the frame of the unit.
      Note: Follow the same precautions you would use without the wrist strap. The 2209 Disposable Wrist Strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
  5. Remove the disk unit covers. Squeeze the latch and pull out.
  6. Locate the disk unit you want to replace.
  7. Unlock the handle by squeezing it and pulling it out toward you before you remove the disk unit.
    If the handle is not all the way out, the disk unit will not slide out of the system.
  8. Support the bottom of the disk unit assembly as you slide it completely out.
    Do not hold the disk unit by the handle.
  9. Find the package that contains the new disk unit assembly and remove it from the static-protective package.
    Write the serial number (use the last 4 digits) of the disk unit here ______________ before you install it.
    Attention: Disk units are fragile. Handle with care.
  10. Squeeze and pull the handle out toward you before you install the disk unit.
    If the handle is not all the way out, the disk unit will not slide into the system unit or the expansion unit. Do not hold the disk unit by the handle.
  11. Make sure that the disk unit handle is fully extended when sliding into the system unit or the expansion unit.
    Support the bottom of the disk unit assembly as you slide it into the system unit or the expansion unit until it stops.
  12. Close the disk unit handle firmly, locking it into place.
  13. Install the disk unit covers.
    Align the tabs on the disk unit enclosure cover with the slots on the system unit enclosure. Push the cover in until it latches.
  14. Install or close the unit front cover.

  15. DANGER
    An electrical outlet that is not correctly wired can place hazardous voltage on metal parts of the system or the products that attach to the system. It is the customer's responsibility to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (RSFTD201) Plug the following power cords into an electrical outlet.
    • System unit
    • System unit console
    • Expansion units
  16. Plug in and power on all attached devices, such as printers and displays.
  17. Activate your logical partition using the HMC.
    There is approximately a 10-second delay before the power-on light comes on, and data appears in the Function/Data display.
    Note: The system takes several minutes to power on and complete an initial program load (IPL). When the IPL is complete, the IBM® i signon display should appear on your system unit console.
