Figure 44 System console during RAID rebuild (HP D2D2500 Series)
If several disks fail
If several disk failures are reported at once, it is possible that the disks are fine while some other
component has failed. In these situations care should be taken to rule out the possibilities of
loose/broken cables, faulty RAID controllers or powered-down Capacity Upgrade Kits before
replacing the disks. If the problem lies with components other than the disks, then there is a very
good chance that no actual data loss has occurred.
NOTE: If the System State shows that RAID has failed catastrophically and no RAID devices are
available, the HP Smart Array RAID controller has failed and needs replacing. See the HP D2D
Backup System Maintenance and Service Guide for more information.
Replacing the disks (HP D2D2500 Series)
If more than one disk fails on the HP D2D2500 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.
