Configuration for Reducing Rebuilding Time
As described in the preceding section, it is important to shorten rebuilding time as far as
possible. You can reduce rebuilding time by configuring hard disks as follows:
For example, when you create two configurations including three 146GB hard disks and a
hot- spare, instead of creating one configuration (900GB) including three 300GB hard disks
and a hot-spare, rebuilding requires less time and risks are reduced.

Measures to be Taken When Rebuilding
To reduce the load on the PC during rebuilding and to shorten the rebuilding time, it is also
recommended to implement the following measures:
Stop the Storage Server program before rebuilding.
Temporarily reduce the recording frame rate during rebuilding.

Notes on Consistency Check of RAID Configuration Information
For stable operation of hard disks, you need to regularly perform consistency check of
RAID configuration information. This is especially effective for preventing data
inconsistency when rebuilding is performed. However, as with rebuilding, the consistency
check of RAID configuration information imposes a burden on the PC for a long period of
time.
In a consistency check of RAID configuration information, measures such as configuring
hard disks in the same way as in rebuilding and reducing the load on the PC, are also
important. Refer to “Measures to be Taken When Rebuilding”.
