Changing hard disk mode
Do the following when the hard disk mode is changed
from SINGLE to RAID5 or vice versa after the system
has been operated.
Skip this section and perform settings in the same way
as "Setup to the SINGLE mode" or "Setup to the RAID5
mode" when the power switches of the recorder and
extension units are accessible.
Important:
• The MODE switches of all extension units in a system
should be set to the same position, SINGLE or RAID5.
Otherwise, the system will malfunction.
• At least, three hard disk drives per extension unit are
needed to run it in the RAID5 mode.
• When the hard disk mode of the extension unit is
changed, all data previously stored in the unit will be
erased.
