Description
This article explains the method to identify what type of RAID the FortiAnalyzer/FortiManager device is running.
If a hard disk on a FortiAnalyzer/FortiManager unit fails, it must be replaced.
On FortiAnalyzer/FortiManager devices that support hardware RAID, the hard disk can be replaced while the unit is still running - known as hot swapping.
On FortiAnalyzer/Fortimanager units with software RAID, the disks are not hot-swappable so the device must be shut down before exchanging the hard disk.
Scope
FortiAnalyzer and FortiManager.
Solution
Use the command line to check if the device uses hardware or software RAID.
To check the RAID type from the command line:
- Go to System Settings.
- Select the CLI Console.
- Enter the following command and press Enter.
diagnose system raid status
The following information is shown in the output:
Mega RAID <-- This output shows that the device uses hardware RAID.
Storcli RAID <-- Newer models use Storcli RAID. This runs on Mega RAID and is also a hardware RAID.
Software RAID <-- This output shows that the device uses software RAID.
Sample command line output showing RAID:
diagnose system raid status
Mega RAID: <-- This is hardware RAID.
RAID Level: Raid-50
RAID Status: OK
RAID Size: 11175GB
Groups: 2
FAZ-3000G # diagnose system raid status
Storcli RAID: <-- This is hardware RAID.
RAID Level: Raid-50
RAID Status: OK
RAID Size: 52156GB

Groups: 2
diagnose system raid status
Software RAID: <-- This is software RAID.
RAID Level: Raid-50
RAID Status: OK
