Initializing VCN510 Disks
When the VCN510 is delivered to the site, recording data can be stored only after you install and initialize the disks.
Procedure
- Log in to the OMU portal of the VCN as the admin user.
- Choose Local Configuration > Local Disk.
- In the upper right corner of the RAID Groups area, click Initial disk, as shown in Figure 1.Figure 1 Initializing disks
- Choose whether to create a RAID group. To set disks as a RAID group, select RAID1. To set disks to work independently, select NON-RAID. Table 1 introduces the disk mode. NOTE:
The VCN510 supports only RAID1 or NON-RAID. If a single disk is configured, the VCN510 supports only non-RAID mode. This document assumes that two disks are configured for the VCN510.
Table 1 Disk modes Disk Mode
Description
RAID1
If RAID1 is used, disks back up each other. After recording data is stored in a disk, the data will be simultaneously backed up to another disk, ensuring high data storage reliability. However, the disk usage of RAID1 is lower than that of disks that work independently.
NON-RAID
If disks work independently, recording data is stored into two disks in sequence, ensuring high disk usage. However, the data storage reliability of disks that work independently is lower than that of RAID1.
- Click Start.
A warning message is displayed.
- Click OK.
It takes about 5 minutes to 10 minutes to initialize disks.
Verification
- Choose Local Configuration > Local Disk.
- In the RAID Groups area, check the RAID group status. The RAID group statuses of RAID1 mode and disks that work independently are shown in Figure 2 and Figure 3 respectively.
If RAID1 is selected for the disks, RAID1 is created for both the system partition (used to store system data) and data partition (used to store recordings).
Figure 2 RAID group status of RAID1When two disks are configured, if NON-RAID is selected for the disks, RAID1 is created for the system partition.
Figure 3 RAID group status of disks that work independently (two disks)If only one disk is configured, RAID 0 is created for the system partition after disks are initialized.
Figure 4 RAID group status of disks that work independently (one disk) NOTE:- After a RAID1 is created for the system partition, the system partition's RAID group is in data restoration state. At this time, one disk is synchronizing data in the system partition to the system partition of another disk. The synchronization process takes about 20 hours, which does not impact services. During this process, do not remove and insert disks.
- If the OMU portal stays at the Local Disk tab page, even if users do not perform any operation for a long period of time, the OMU portal will not automatically return to the login page. For service security reasons, if users do not perform any operation for a long period of time, the OMU portal will return to the login page or does not stay at the Local Disk tab page.
