In the
Information
screen, you can enable mirroring between two disks by designating the source disk
and the destination disk from internal hard disk drives. The disk installed in the top-left removable hard
disk drive rack is named “
Internal 1
”, the bottom-left drive is “
Internal 2
”, the top-left drive is “
Internal
3
” and the bottom-right drive is “
Internal 4
”. Up to two Mirrors are supported. Disk mirroring can be
made between
Internal
1
and
Internal
2
and between
Internal
3
and
Internal
4
.
Highlight the first or second box under
Mirroring Setup
and press the button.
You will be able to organize two disks used for mirroring (Source Disk
Æ
Destination Disk) for Mirror 1 or Mirror 2.
Figure 131 — Mirroring setup screen.
NOTE: The source disk can be designated only from devices formatted for recording.
NOTE: A device formatted for archiving cannot be used for disk mirroring.
NOTE: The manufacturer, model and capacity of the source disk and the destination disk should
be same for the proper mirroring between two disks.
Selecting the source disk and the destination disk displays a confirmation screen asking you to confirm
whether or not you want to start mirroring for the selected Mirror.
CAUTION: Any existing data on the Destination Disk will be erased once it is designated
as a mirror destination disk.
Once you start mirroring, the two disks will be resynchronized. Any data on the destination disk will be
erased, and the data on the source disk will be copied to the destination disk. If the source disk is formatted
and has no data, the disks will not be resynchronized. Resynchronization takes about 40 minutes per each
10GB of capacity. After resynchronization is complete, disk mirroring (writing data on the two disks at the
same time) will start. The icon displays on the screen and the mirroring LED is lit on the front panel
while disks are mirroring.
NOTE: During resynchronization, the maximum recording speed will be adjusted to 240 ips with
Half D1 resolution.
Once disk mirroring starts, you can cancel it by selecting
No Mirror
in the Mirroring setup screen.
Selecting No Mirror displays a confirmation screen asking you to confirm whether or not you want to
stop mirroring for the selected Mirror.
NOTE: Once disk mirroring stops, the destination disk will be set to
Not Used
. If resynchronization
has been finished, the destination disk cannot be used for recording or archiving, but it can be
used for searching. If you want to use the disk for recording or archiving, you must reformat it.
CAUTION: Disk mirroring will NOT automatically restart from an interrupted state. Once
mirroring is stopped, you must restart it by following the mirroring setup procedures.
