  12. Look for the disk drive at the PCI location you recorded. The disk drive might have a Failed status.
  13. If the disk drive you want to replace is unprotected or in use, move the data from the disk drive before continuing with this procedure.

    For information, see the PCI-X SCSI RAID Controller Reference Guide for Linux.

    This guide is available from the SCSI PCI Adapters web page.

  14. Type option 1 (Display hardware resource information details) next to the disk drive you want to replace. Press Enter.

    The Disk Hardware Resource Information Details is displayed like the shown in the following sample.

  4. Type option 1 (Select) next to the location for the disk drive you want to replace. Press Enter.
  5. The Verify Device Concurrent Remove display is shown. The concurrent maintenance light turns on for that disk drive slot. To view the locations of the concurrent maintenance lights, select the appropriate model from the following list:
  6. On the Verify Device Concurrent Remove display, verify that the selected disk drive is the disk drive you want to replace, then press Enter. The identify light turns on for the disk drive.
    Note: Ensure that the disk drive is not in use to prevent loss of data.
  7. The Device Concurrent Remove display is shown.
    Attention:
    • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
    • When using a wrist strap, follow all electrical safety procedures. A 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.
    • If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
  8. Squeeze and pull the handle of the disk drive out toward you before you remove the disk drive as shown in Figure 5. If the handle is not all the way out, the disk drive does not slide out of the system or expansion unit.
    Figure 5. Removing a disk drive from a model or 7311-D20
    Graphic of removing a disk drive form the system unit.
  9. 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.
  10. Press Enter on the IBM Power RAID Configuration Utility to indicate that you have removed the disk drive.
