A created <Array> displays as an HDD in the <HDD Information> interface.
13.1.3 Manually Creating the Array
You can manually create the array of <RAID 0>, RAID 1>, <RAID 5>, RAID 6> and <RAID 10>.
Note:
In this section, we take <RAID 5> as an example to describe the manual configuration of an <Array> and a
<Virtual Disk>.
Steps:
1.
Enter the <Physical Disk Settings> interface: Menu > HDD > RAID > Physical Disk
2.
Click the <Create> button to enter the <Create Array> interface.
3.
Edit the <Array Name>; set the <RAID Level> to <RAID 0>, <RAID 1>, <RAID 5>, RAID 6> or <RAID
10>; select the Physical Disk that you want to configure for the <Array>.
Note:
If you choose <RAID 0>, at least 2 HDDs must be installed.
If you choose <RAID 1>, 2 HDDs need to be configured for <RAID 1>.
If you choose <RAID 5>, at least 3 HDDs must be installed.
If you choose <RAID 6>, at least 4 HDDs must be installed.
If you choose <RAID 10>, the number of HDDs installed should be even in the range of <4> to <16>.
4.
Click the <OK> button to create the <Array>.
Note:
If the number of HDDs you select is not compatible with the requirement of the <RAID Level>, the error
message box will pop up.
5.
You can click the <Array> tab to view the successfully created <Array>.
13.2 Rebuilding the Array
The working status of an <Array> includes <Functional>, <Degraded> and <Offline>. By viewing the
<Array Status>, you can perform immediate and proper maintenance for the disks so as to ensure the
high security and the reliability of the data stored in the <Disk Array>.
When there is no <Disk Loss> in the <Array>, the working status of the <Array> will change to
<Functional>; when the number of lost disks has exceeded the limit, the working status of the <Array>
will change to <Offline>; in other conditions, the working status is <Degraded>.
When the <Virtual Disk> shows a <Degraded> status, you can restore it to <Functional> by <Array
Rebuilding>.
Before you start:
Please make sure the <Hot Spare>disk is configured.
1.
Enter the <Physical Disk Settings> interface to configure the <Hot Spare> disk.
2.
Select a disk and click to set it as the <Hot Spare> disk.
