Hot-swapping hard disk
If a hard disk on a FortiSandbox unit fails, it must be replaced. FortiSandbox devices support hardware RAID and the hard disk can be replaced while the FortiSandbox unit is running, also known as hot-swapping.
The following table shows the default RAID level on different models.
|
FortiSandbox model |
Default RAID Level |
|---|---|
|
FSA-500F |
N/A |
|
FSA-1000F/-DC |
RAID-1 |
|
FSA-2000E |
RAID-1 |
|
FSA-3000E |
RAID-10 |
|
FSA-3000F |
RAID-10 |
To identify which hard disk failed the following diagnostic commands are available:
|
|
Display general hardware status information. Use this command to view CPU, memory, disk, and RAID information, and system time settings. |
|
|
Display system disk attributes. |
|
|
Display any system disk errors. |
|
|
Display disk health information. |
|
|
Display disk hardware status information. |
|
|
Display RAID hardware status information. |
To hot-swap a hard disk on a device that supports hardware RAID, simply remove the faulty hard disk and replace it.

Electrostatic discharge (ESD) can damage FortiSandbox equipment. Only perform the procedures described in this document from an ESD workstation. If no such station is available, you can provide some ESD protection by wearing an anti-static wrist or ankle strap and attaching it to an ESD connector or to a metal part of a FortiSandbox chassis. When replacing a hard disk, you need to first verify that the new disk has the same size as those supplied by Fortinet and has at least the same capacity as the old one in the FortiSandbox unit. Installing a smaller hard disk will affect the RAID setup and may cause data loss. Due to possible differences in sector layout between disks, the only way to guarantee that two disks have the same size is to use the same brand and model. The size provided by the hard drive manufacturer for a given disk model is only an approximation. The exact size is determined by the number of sectors present on the disk. |
The FortiSandbox unit will automatically add the new disk to the current RAID array. The status appears on the console. The RAID Management page will display a green checkmark icon for all disks and the RAID Status area will display the progress of the RAID re-synchronization/rebuild.

Once a RAID array is built, adding another disk with the same capacity will not affect the array size until you rebuild the array by restarting the FortiSandbox unit. |
