Replacing the disks (HP D2D4300/4100 Series)
If more than two disks fail and the online spare disk has been used on the HP D2D4300/4100
Series, you will lose all data on the HP StoreOnce Backup System and the message on the Summary
page warns that the RAID system has failed catastrophically. The RAID is not recoverable.

The device operating system is not stored on any of the disks, so the HP D2D Backup System is
still usable after replacing the failed disks. Use the Beacon function on the Storage-Shelves page
of the Web Management Interface or the System Console to help you identify the disks that have
failed.
