Changing the FortiGate-7000F log disk and RAID configuration
Each FIM-7941F or FIM-7921F installed in a FortiGate-7000F contains two 4TByte SSD log disks in a RAID-1 configuration. In the RAID-1 configuration, you can use the disks for disk logging only.
You can log into the CLI of each FIM and use the execute disk command to view and change the configuration and RAID level of the disks. Changing the configuration or RAID level deletes all data from the disks and can disrupt disk logging. A best practice is set the disk configuration and RAID level when initially setting up the FortiGate-7000F.
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 execute disk raid status command to show RAID status.
The following command output shows the RAID status of the 4TByte SSDs configured for RAID-1.
execute disk raid status RAID Level: Raid-1 RAID Status: OK RAID Size: 4000GB Disk 1: OK Used 3815GB Disk 2: OK Used 3815GB
