How do I know a disk has failed?
The Disk online LED (1) on the failed disk shows amber.

Identifying a failed disk on the Web Management Interface
The Web Management Interface identifies failed or predictive failed disks.
•
HP D2D4300 and HP D2D4100 Series Backup Systems operate correctly with up to two failed
disks on the HP D2D and up to two failed disks in any Capacity Upgrade Kit that is installed.
•
HP D2D2500 Series Backup Systems operate correctly with one failed disk.
It is important to replace a failed or predictive failed disks as soon as possible. Any subsequent disk
failure will result in complete data loss.
NOTE:
The first disk (HP D2D4300 Series) or the 12th disk (HP D2D4100 Series) on the internal shelf and
the 12th disk on any expansion shelves are the online spare disks. If a disk fails, the online spare disk
will immediately be used to replace it. The RAID rebuild process occurs automatically. The failed disk
should always be replaced as soon as possible.
Summary page information
Look at the
Summary
page. For example:
•
HP D2D4100/4300 Series: If it shows see that RAID is building, but is fully operational and that
Storage needs attention, this probably means that a disk has failed and the online spare is being
used. The
Storage (Status)
tabs will provide more information.
•
HP D2D2500 Series: If you can see that RAID status has failed, but it is recoverable, this means
that one disk has failed.
