smallest hard disk will be used. For example, if the RAID has 400 GB disks, and you replace one with a 500 GB disk, to
be consistent with the other disks, only 400 GB of the new disk will be used.
FortiRecorder units support hot swap; shutting down the unit during hard disk replacement is not required.
To replace a disk in the array
1. Go to System > Storage > Local Storage .
2. In the row corresponding to the hard disk that you want to replace (for example, p4 ), select the hard disk and click
Delete .
3. The RAID controller removes the hard disk from the list.
4. Protect the FortiRecorder unit from static electricity by using measures such as applying an antistatic wrist strap.
5. Physically remove the hard disk that corresponds to the one you removed in the GUI from its drive bay.
6. Replace the hard disk with a new hard disk, inserting it into its drive bay.
7. Click Refresh .
The RAID controller will scan for available hard disks and should locate the new hard disk. Depending on the RAID
level, the FortiRecorder unit may either automatically add the new hard disk to the RAID unit or allocate it as a
spare that will be automatically added to the array if one of the hard disks in the array fails.
The FortiRecorder unit rebuilds the RAID array with the new hard disk. Time required varies by the size of the array.
Replacing all RAID disks
If you want to replace the pre-installed hard drives with your own on FortiRecorder and re-build the RAID array, follow
these instructions.
To replace all disks in the array
1.
Back up the configuration
Because the X.509 certificates used by SSL/TLS connections are stored on the hard drive(s), rebuilding the array
with new disks removes those certificates. Certificates are included in the configuration file backup, however. After
you install the new hard drives, restore the configuration.
(Skip this step if you do not use the factory certificates and can re-import your own custom certificates later.)
2. Shut down the FortiRecorder unit.
3. Remove the hard disks.
4. Install the new hard disks.
5. Boot up the system.
6. Enter the following CLI command to rebuild the disks:
execute factoryreset disk
This command will use the default RAID level based on the number of drives used. You can also use the following
command to rebuild the disks with the specified RAID level. For the supported RAID levels, see
levels on page
73.
execute raidlevel <level_int>
The FortiRecorder sets the RAID level and then reboots.
Configuring external storage
To extend your local storage, you can use an external USB storage device if your FortiRecorder model has USB ports.
