Removing a Bad Drive and Replacing with a New Drive

If you remove a bad drive and put in a new replacement drive, the drive will rebuild automatically. You do not have to shut down the server to replace a bad drive with a new one. You will want to use the Storage Utility Property window to view and record the serial number of the bad disk. (This is highly recommended so you don’t confuse the bad disk drive with the new known good drive. Replacing a bad drive back in the system can cause several problems.)

  1. Open the Storage Utility application.
  2. Identify the disk that you need to replace. From the Storage Utility view tree, look at the bound LUNs and identify the bad disk. The disk will be unbound, appear in the view tree with a red X and the state of the disk will appear as Fault.

  3. Close the Storage Utility application.
  4. Remove the thumbscrews to free the bezel from the front of the chassis. Note that all the LEDs for the disks in the LUN are flashing amber.
  5. Count to the disk in the chassis that is bad. The LED on the bad drive should flash amber to green. The numbering of disk drives in the chassis is (left to right 2-7).

  6. Remove the thumbscrews to release the drive.
  7. Make a note of the bad drive’s serial number. This is important because you do not want to replace the bad drive in the system.
  8. Place the new drive in the chassis.
  9. Replace the bezel on the front of the chassis.
  10. Start the Storage Utility application. Note that the whole LUN has been degraded.
  11. From the tree view, select the new disk.
  12. Select Refresh from the View menu (to see the disk rebuilding.) The disk automatically rebuilds.
