Appendix E: Enabling soft RAID on KVM or VMware

To expand hard disk capacity, you can enable RAID on the FortiPAM-VM. After RAID is enabled, hard disk capacity can be expanded from 2 TB to 16 TB.

Individual disks of sizes up to 2 TB are supported.

Soft RAID is supported on KVM and VMware platforms. Hyper-V and other platforms are not supported yet.

Note: Soft RAID for VMware requires disks of the same size.

RAID can only be configured using the CLI commands.

Enabling, disabling, and changing the RAID level, erases all the data on the log and video disk. Also, the FortiPAM device reboots every time RAID is enabled, disabled, or the RAID level is changed.

To configure RAID via CLI:

1. Before enabling RAID, enter the following command in the CLI console to verify that the FortiPAM has multiple disks:

   execute disk list

   or

   diagnose hardware deviceinfo disk

2. In the CLI console, enter the following command to enable RAID:

   execute disk raid enable <RAID level> #The default value is Raid-0

   Two partitions will be created after RAID is enabled. One partition for log and one for video.

   To disable RAID, enter execute disk raid disable.

   When there are two disks, RAID level 0 and 1 are available. Only when there are four disks, RAID level 5 and 10 are available.

3. From the Admin dropdown in the banner, go to System > Reboot to reboot FortiPAM.

   Reboot is only available when FortiPAM is in maintenance mode. To enable the maintenance mode, see Enabling maintenance mode.

4. In the Reboot window, click OK to confirm.

   Optionally, enter an event log message.

5. In the CLI console, check the RAID status by entering the following command:

   execute disk raid status #Raid is now available

   If the above steps do not enable RAID on FortiPAM-VM, use the following workaround: Factory reset your FortiPAM-VM. Remove disk from your FortiPAM-VM, then add the disk again. Now follow the steps in Configuring RAID via CLI.

Rebuilding a RAID with a different RAID level

Admin can only rebuild RAID at the same RAID level if a RAID error has been detected. Also, changing the RAID level takes a while and deletes all data on the disk.

Use the following CLI command to rebuild RAID:

execute disk raid rebuild-level <RAID level>
