Using the command line interface (CLI) : config : config system raid
 
config system raid
The config system raid command allows you to view or configure the hard disk RAID scheme.
Syntax
config system raid
set level <raid_level_name>
end
where:
Variable
Description
Default
<raid_level_name>
Specifies the RAID level.
Valid values are determined by the FortiDB model and hard disk hardware.
raid1
 
Implementing RAID removes all existing data from the hard disks.
FortiDB 2000B supports raid1 and raid5 only. To determine which RAID scheme your appliance supports, see your hardware specification.
The appliance requires a minimum of 2 hard disks to implement RAID.
After you implement RAID, you cannot return the hard disk to its original partitions.
 
Use CLI get system raid to get the RAID level information.
Use CLI diagnose system raid list to get current RAID status information.
If the RAID schema is corrupted, use CLI execute raid rebuild to rebuild it.
Implementing RAID 5 on FortiDB 2000B
The RAID 5 array requires at least 3 hard disks. You cannot implement RAID 5 on FortiDB 2000B if fewer than 3 hard disks are available.
To ensure the hard disks have the same parameters, ensure they all have the same capacity, model, and vendor.
To remove the RAID 5 array
The unset operation removes the RAID 5 array and all data is lost. Perform this operation only if it is necessary.
1. Using the CLI, log in to the FortiDB 2000B as the user admin.
2. To enter RAID configuration, enter config system raid.
3. Enter unset level.
FortiDB prompts you to confirm the action and warns you that all the data on all hard disks will be lost.
4. To continue, enter y.
FortiDB starts the RAID 5 unset operation.
5. To format the hard disk, enter execute format disk.
FortiDB reboots automatically. After the reboot, FortiDB is available on the first hard disk.
Implementing RAID on FortiDB 3000B
FortiDB 3000D has an integrated RAID controller that supports RAID 0, 1, 5, 10, and other standard levels.
However, you cannot use the CLI commands to implement RAID on FortiDB 3000D. Instead, you set the RAID level in BIOS.
To access the FortiDB 3000D BIOS, a keyboard and a display device are required.
To enter the BIOS Configuration Utility, when the BIOS screen is displayed during startup, press CTRL-R.
After you change RAID level, you must format the hard disk. To obtain the required format image, contact Fortinet Technical Support.
