Aibase color raid setup instruction

Step by Step instruction

1. RAID
   The RAID function has a high requirement on hard disk performance. To ensure long-term stable operation and reliability of RAID, it is recommended that you use enterprise-class hard disks (including brand, model, and capacity) for RAID creation and other configurations. If surveillance-class or desktop-class hard disks are used, data security may be affected.

1.1. Enabling RAID
Choose Main Menu > System > General to open the general setting page. Select Enable Raid to enable the RAID function, and then save the configuration. The configuration will take effect after the system is restarted.

Note: After the RAID function is enabled, the NVR does not support ESATA and NAS.
1.2. Creating RAID
You can create RAID either in one click or manually. For one-click creation, RAID5 is created by default. For manual creation, RAID0, RAID1, RAID5, RAID6, and RAID10 are supported. You can create different types of RAID in accordance with the actual number of hard disks to be accessed.
Hard Disk Quantity for RAID Creation
Raid0 >=2
RAID1 2
RAID5 ≥ 3
RAID6 ≥ 4
RAID10 4 or 8
Note:The capacity of a single hard disk used for RAID creation is not less than 4 TB. For an installed hard disk with a capacity less than 4 TB, it cannot be selected for RAID creation.
(1）Automatic RAID Creation

• Through one-click configuration, the device can quickly create RAID and virtual disks. RAID5 is created by default in one-click configuration, and at least four hard disks should be installed.

(2) Creating RAID Manually
To create RAID manually, click Create RAID to open the Create RAID page. Set the RAID name, select the RAID type, select the hard disks, and click OK to create the RAID. After the RAID is created, format the RAID.

To enable the RAID for normal use, you need to format the RAID first. After RAID formatting is completed, open the disk group configuration page, select the disk group and recording channels, and ensure that camera recording is normal.

1.3. Setting Hot Spare Disks
To ensure RAID security, when RAID is in degraded status, the system can automatically carry out RAID rebuilding. Therefore, it is recommended that hot spare disks be configured.
On the RAID configuration page, select an idle hard disk, click the Add HotDisk button, and confirm the hot spare disk setting. (Hot spare disks are public disks and can be used by all created RAIDs.)

1.4. Rebuilding RAID
The operational status of a RAID includes normal, degraded, and offline. To give full play to RAID advantages and ensure the security and reliability of data storage, you can maintain the disks in a timely manner by viewing RAID status. For a RAID, when there is no physical disk loss, the RAID is in normal status; when the number of physical disks lost exceeds the threshold for the RAID type, the RAID is in offline status; when the actual situation is between the two cases, the RAID is in degraded status. When a RAID is in degraded status, it can be restored to normal status through RAID rebuilding.
(1) Rebuilding RAID Automatically
Automatic RAID rebuilding requires that the device should be configured with hot spare disks in advance and the hot spare disk capacity should be not less than the capacity of the smallest disk of the RAID. If the above conditions are met, when a hard disk in a RAID is lost or damaged, the hot spare disk is activated and considered as a candidate disk for the RAID, and then the automatic rebuilding task is started.
For example, RAID5 consists of hard disks 1, 2, and 3, and hard disk 4 has been configured as a hot spare disk. Hard disk 2 fails in operation, and the system does not detect it. Therefore, RAID5 is in degraded status, and hard disk 4 is immediately activated and considered as a candidate disk. Then, the rebuilding process is started.

(2) Rebuilding RAID Manually
When a RAID is in degraded status, if it has no hot spare disk, automatically rebuilding cannot be implemented. You need to manually rebuild the RAID to restore it to normal status.
On the RAID configuration page, select an idle disk, and click the Rebuild RAID button, verify the password, and then start RAID rebuilding. After the rebuilding is completed, the RAID is restored to normal status.

1.5 Deleting RAID
Select the RAID to be deleted, click the Delete RAID button, enter the administrator password, and click OK to delete the RAID.

1.6 Viewing RAID Information
Click the RAID Info button to open the RAID Info page to view the RAID function information.
