The FortiGate-6301F and FortiGate-6501F both include two internal 1-TByte log disks. By default the disks are in a RAID-1 configuration. In the RAID-1 configuration you can use the disks for disk logging only. You can use the
execute disk raid command to disable RAID and use one of the disks for disk logging and the other for other purposes such as disk caching. You can also change the RAID level to RAID-0. Changing the RAID configuration deletes all data from the disks and can disrupt disk logging so a best practice is set the RAID configuration when initially setting up the FortiGate-6301F or 6501F.
From the CLI you can use the following command to show disk status:
execute disk list
Use the following command to disable RAID:
execute disk raid disable
RAID is disabled, the disks are separated and formatted.
Use the following command to change the RAID level to RAID-0:
execute disk raid rebuild-level 0
The disks are formatted for RAID-0.
Use the following command to rebuild the current RAID partition:
execute disk raid rebuild
The RAID is rebuilt at the current RAID level.
Use the following command to show RAID status. The following command output shows the disks configured for RAID-1.
execute disk raid status RAID Level: Raid-1 RAID Status: OK RAID Size: 1000GB Disk 1: OK Used 953GB Disk 2: OK Used 953GB
