Physical disks When you select a shelf, the disks within it are displayed in the Physical Disks section.

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.
Disk:
This is the status of the physical disk. Possible states are - OK, Failed, Missing,
Too Small, Rebuilding, Predictive Failure.
State:
This is the product number of the disk.
Description:
This is the serial number of the disk. Always make a note of this before
replacing a failed disk.
Serial No:
This is the software version of the disk. It may be useful for troubleshooting
and when replacing a disk.
FW Version:
This is 2 TB (HP D2D4324), 1 TB (HP D2D4112/4312) or 500 GB (HP
D2D4106). This shows the size of each disk in your StoreOnce Backup
System. The sum of the disks gives 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.
Size:
This indicates the location of the online spare disk. It is normally:
•
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
Spare:
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.

Disk (Status)
This page provides information about total disk usage and disk usage for each library and NAS share
