Physical disks
When you select a shelf, the disks within it are displayed in the Physical Disks section. Use the
information in this section to identify disks that may be failing or disks that are approaching
capacity.
IMPORTANT: If you need to replace a disk, it is very important to obtain the serial number and
the physical location of the failed disk from this page before you replace it. We strongly recommend
that you use this page to beacon a disk within the StoreOnce Backup System. The Beacon LED on
the front of the individual disk will show solid blue.
This indicates the physical location of the disk and is useful if you need to replace a disk.
Always double check against the serial number after removing a disk.

the total raw capacity available. However, the usable capacity is always less due to the
RAID configuration used across the disks. See the Storage glossary entry for more information.
This indicates the location of the online spare disk. It is normally:Spare:
• HP D2D4300 Series: Disk 1 for the internal shelf and Disk 12 for an expansion shelf
• HP D2D4100 Series: Disk 12
The box will be unchecked if a disk fails and the online spare takes over from the failed
disk. Once you replace the disk and the RAID rebuilds, the box against Disk 1 or Disk 12
is checked again as it resumes its function of online spare disk
Check this box to beacon the LED on the front of the disk. This helps you identify the disk
that needs attention and the shelf that contains it.
