      2. The recover configuration function cannot be performed on a system with only one disk unit. A message may appear stating that your request to recover the configuration was not successful.
    5. Continue with the next step.
  16. The ASP to which the failing disk unit was assigned is cleared. The customer should do the following:
  17. Is the failing unit missing from the configuration?
  18. Perform the following to install a new disk unit on the system:

    1. Power off the system and remove the power cords.

      The component will not be serviced concurrently.

      If this system is powered on, power it off before continuing.

      If possible, shut down any running applications and the operating system before powering off the system.

      Once the system is powered off, remove all power cords from all of the processor enclosures starting with the primary processor enclosure (topmost) and then each secondary enclosure working from top to bottom.

    2. Access the unit.

      1. Open the front rack door.
      2. Loosen the thumbscrew (A) on the right side of the cover.
      3. Slide the cover to the right and remove it from the system unit slot (B).

    3. Remove the disk drive.

      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.

    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.

    5. Install the disk drive.

      1. Support the bottom of the disk drive as you align it with the guide rails in the system unit. Do not hold the disk drive by the handle.
      2. Slide the disk drive into the system until it stops.
      3. Push the disk drive handle in until it locks.
        Note:
        It is important to ensure that when installing a disk drive, that the drive is fully seated and all the way into the system.

    6. Install the power cords.

      If you removed the power cords, reinstall the power cords for all of the processor enclosures.

      Install the cords in the following order:

      1. Secondary 2
      2. Secondary 3
      3. Primary
      4. Secondary 1
  19. Perform an IPL to DST (see Performing an IPL to DST). Does the Use Dedicated Service Tools (DST) display appear?
  20. Perform the following to format and initialize the disk drive you installed in step 18:
    1. From the Use Dedicated Service Tools (DST) display, select Work with disk units -> Work with disk unit recovery -> Disk unit problem recovery procedures -> Initialize and format disk unit.
    2. Select the unconfigured disk unit that you installed in step 18 as the unit to work with.
    3. Press F10 to verify the initialization and formatting. The initialization and formatting may take 30 minutes or longer to complete.
    4. Return to the Work with Disk Unit Recovery display.
  21. Perform the following to copy data from the failing disk drive to the disk drive you installed in step 18:
    1. Select Copy disk unit data on the Work with Disk Unit Recovery display.
    2. Select the failing unit as the unit to copy.
    3. Select the unconfigured unit that you installed in step 18 as the unit to copy to.
    4. The console displays the percentage of the data copied. Write down the number of unreadable pages if it displays; you will use it later in this procedure.
    5. Wait until the status of the copy is Complete. Continue with the next step.
      Note:
      Customer data is not recoverable if one of the following occurs:
      • The copy operation does not complete.
      • A large number of unreadable pages must be copied from the disk unit.
  22. Perform the following to remove the failing disk unit from the system:
    1. Power off the system.
    2. Find the failing disk unit. Slide the disk unit out of the system.
  23. Perform the following to move the new disk unit into the location that held the failing disk unit:
    1. Remove the new disk unit from the location you found in step 17. Be very careful with the disk unit--it contains sensitive data.
    2. Install the new disk unit into the location that contained the failing disk unit, which you removed in step 22.
  24. Install the disk unit you removed in step 18.
  25. Were any pages unreadable during the copy operation performed in step 21?
  26. Are there multiple failing disk units under the same IOA?
  27. Because the disk data was not recoverable, clear the auxiliary storage pool (ASP) to which the disk unit is assigned by doing the following:
    1. Return to the Work with Disk Units display and select Work with disk configuration -> Work with ASP configuration -> Delete ASP data.
    2. Enter Delete for the ASP that you recorded in step 3, and confirm the deletion.
    3. Return to the Work with Disk Units display and select Work with disk unit recovery -> Replace configured unit.
    4. On the Select Configured Unit to Replace display, select the configured disk unit to exchange.
    5. On the Select Replacement Unit display, select the replacement disk unit.
    6. Press Enter to confirm the replace operation (this operation takes 10 to 15 minutes to complete). The auxiliary storage pool to which the disk unit is assigned was erased. The customer must restore the data to the auxiliary storage pool. Refer the customer to Backup and Recovery, SC41-5304.
  28. The ASP to which the failing disk unit was assigned is cleared. The customer should do the following:

Restoring profile data

Explains how to read the profile data from the previously backed-up file on the HMC and load this data to the managed system.

Selecting this menu item restores profile data to the HMC from a backup file stored on the HMC hard drive.

Note:
This is not a concurrent procedure. When the data is restored, the managed system powers on to Partition Standby.

To restore stored profile data on the HMC hard drive, you must be a member of one of the following roles:

To restore profile data, do the following:

  1. In the Contents area, select the managed system.
  2. From the menu, select Selected > Profile Data > Restore.
  3. Select the profile information that you want to restore from the list of backup files.
  4. Select a restore option.
