Замена жесткого диска в серверах PowerSytems i (AS/400)

Posted on by

Как известно, технология, похожая на PnP появилась в OS/400 раньше, чем в Windows.

Поэтому замена оборудования в серверах, работающих под этой операционной системой, обычно проблемы не составляет.

Однако, не бывает ничего абсолютно надежного и, как показала практика, иногда OS/400 не распознает даже новый жесткий диск, установленный взамен старого.

Если это случается, необходимо выполнить процедуру сброса порта RAID-контроллера через STRSST ->Hardware Service Manager ->  Device Concurrent Maintenance.

Самое любопытное, что на эту процедуру системой отводится 18 секунд.

9, чтобы диск извлечь и 9, чтобы вставить другой на замену извлеченному.

Вот тут описан процесс для OS/400 v3.1.5, но в шестой версии все точно так же.

    7. Set the time delay for one minute: 01. Important: Do not press Enter at this time.
    8. Locate the concurrent maintenance light that corresponds to the position of the disk drive that you are replacing
      Note: When you press Enter, after a one minute delay, this light comes on and begins to blink rapidly. You then have nine seconds to remove the disk drive.
    9. Press Enter on the console.
    10. When the light blinks rapidly, perform the next step to remove the disk drive within 9 seconds.
  2. Remove the disk drive by:

    1. Unlock the disk drive handle by squeezing it and pulling it out toward you as shown.
    2. Support the bottom of the disk drive as you slide it out of the system or expansion unit. Do not hold the disk drive by the handle.The concurrent maintenance light for the slot turns off when you remove the disk drive.
  3. Loosen and pull out on the thumbscrew B to release the disk-drive bezel C from the disk drive, as shown in the graphic.Continue with the next step.
  4. Install the bezel on the new disk drive:

    1. Find the package that contains the new disk drive.
      Attention: Disk drives are fragile. Handle with care.
    2. Remove the disk drive from its static protective package.
    3. Unlock the handle of the replacement disk drive by squeezing and pulling it out toward you. If the handle is not all the way out, the disk drive will not slide into the system.
    4. Attach the disk drive bezel A to the replacement disk drive as shown.
    5. Press in and then tighten the thumbscrew B to secure the bezel to the disk drive.
    1. Return to the console and wait until the Concurrent Maintenance Results display is shown. Press F12.
    2. The physical locations you entered in step 6 of this procedure might still appear on the display. If not, retype the physical location where you will be installing the new disk drive.
    3. Select option 2 (Install device) for the Action to be performed.
    4. Set the time delay for one minute: 01.
