FortiRecorder 2.4.2 Administration Guide
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
.
The RAID controller removes the hard disk from the list.
3.
Protect the FortiRecorder unit from static electricity by using measures such as applying an
antistatic wrist strap.
4.
Physically remove the hard disk that corresponds to the one you removed in the web UI from
its drive bay.
5.
Replace the hard disk with a new hard disk, inserting it into its drive bay.
6.
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 both of the pre-installed hard drives with your own on FortiRecorder 400B
and build the RAID array from scratch, follow these instructions.
Because the HTTPs certificates are stored on the hard drive, if you still need them, you must
back up the configuration first. The certificates will be backed up in the configuration file. After
you install the new hard drives, restore the configuration. But if you're not using the factory
certificates and you're planning to import your own certificate later on, you don't have to back
up the configuration/certificates.
To replace all disks in the array
1.
Shut down the FortiRecorder unit.
2.
Remove the hard disks.
3.
Install the new hard disks.
4.
Boot up the system.
5.
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
“Configuring RAID levels” on page 81
execute raidlevel <level>
6.
The system will reboot.
