15.3.22 Configuring Hard Drive Groups (Advanced)
Hard drive groups allow you to balance recordings across multiple hard drives. For exam-
ple, you can record channels 1~4 to one hard drive and 4~8 to a second hard drive. This
can reduce the amount of wear on the hard drives and may extend the life of the hard
drives.
Note
• Two hard drives must be installed in the system to use hard drive groups, and both hard drives must
be formatted as Read-write hard drives. For details on installing hard drives, see 21 LNR400 Series
Hard Drive Installation, page 170.
To configure hard drive groups:
1. From the Main Menu, click
and then click Storage>HDD Advance>HDD
Setting.
2. Under HDD Group, assign a group to each hard drive. To set up two hard drive
groups, assign one hard drive to group 1 and the other to group 2.
3. Click OK. The system will restart to apply changes.
4. When the system restarts, you must decide which channels will record to each hard
drive group.
