Tip: If the description still shows “You can replace this hard drive” and the status of

the drive volume says “Ready”, it means the RAID volume is still expandable.

Migrate (Online RAID Level Migration)

During the initial setup of the NVR, you bought a 250GB hard drive and configured it

as single disk.

After a period of time, more and more important recordings are saved on the NVR.

There is a rising concern for hard drive damage and data loss. Therefore, you planned

to upgrade the disk configuration to RAID 5.

You can install one hard drive for setting up the NVR and upgrade the RAID level of

the NVR with online RAID level migration in the future. The migration process can be

done without turning off the NVR. All the data will be retained.

You can do the following with online RAID level migration:

•

Migrate the system from single disk to RAID 1, RAID 5, RAID 6 or RAID 10

•

Migrate the system from RAID 1 to RAID 5, RAID 6 or RAID 10

•

Migrate the system from RAID 5 with 3 hard drives to RAID 6

You need to:

•

Prepare a hard drive of the same or larger capacity as an existing drive in the

RAID configuration.

•

Execute RAID level migration (migrate the system from single disk mode to RAID 5

with 4 hard drives).

Go to “Storage Manager” > “Volume Management”. The current disk volume

configuration displayed on the page is single disk (the capacity is 250GB).
