NAS shares disk usage

and whether deduplication is enabled. The list will be empty if the StoreOnce Backup System is
offline or if no NAS shares have been created.
RAID
The RAID tab shows the status of the RAID controller and the logical units.
The following screen shot is from an HP D2D4300 Series model. HP D2D4100 Series models only
have one RAID controller.
RAID controllers
This is the ID of the RAID controller.
HP D2D4300 Series: There is an entry for the internal shelf and each expansion shelf that
has been installed. Expansion shelves are identified by the slot number. Select a shelf to
display information about its logical units.
RAID Controllers:
HP D2D4100 Series: There is only one in the current system.
In normal operation, this shows green, OK. If a battery fails, please replace it as soon as
possible. The status of the RAID and the RAID battery are also shown on the Summary page.
RAID Battery:
See the HP StoreOnce Backup System Maintenance and Service Guide for more information
about replacing the RAID battery.
Logical units
Each shelf consists of two logical units. The smaller unit contains configuration information; the
larger unit contains the data. These units always act as pairs.
The Erase button is only active if any RAID has failed and is not recoverable. The logical units must
be erased from the bottom up (start with the highest Logical Unit number and work backwards).
Use with care and only when advised to do so by HP Customer Support.
This is a unique ID for the logical unit.
Logical Unit ID:
This is the status of the logical unit.
Status:
This is the RAID state of the logical unit. The only time the RAID state may be different for
pairs of logical units is when the RAID is rebuilding or initializing/optimizing.
RAID State:
