Description
Since FortiOS 5.6.1, administrators are no longer able to configure RAID for supported FortiGates on GUI. These are FortiGates with dual HDDs/SSDs such as the FG-301E, FG-501E and FG-1500D.
Scope
FortiOS 5.6.1 and above.
Solution
This can be done via CLI. For example:
execute disk list
Disk SSD1 ref: 255 223.6GiB type: SSD [ATA SSDSC2BR240G7] dev: /dev/sda
partition ref: 1 220.1GiB, 219.9GiB free mounted: Y label: LOGUSEDXF79CC331 dev: /dev/sda1 start: 2048
Disk SSD2 ref: 16 223.6GiB type: SSD [ATA SSDSC2BR240G7] dev: /dev/sdb
partition ref: 17 62.7GiB, 62.5GiB free mounted: N label: UNUSEDXX9A2B634F dev: /dev/sdb1 start: 2048
execute disk raid enable raid-1
This will erase all data on the log disk, and system will reboot!
