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.
