Hot swap an SSD

If you have two SSDs, they form a RAID when you boot up. You can perform the following tasks at the Firewall Threat Defense CLI while the firewall is powered up:

Hot swap one of the SSDs—If an SSD is faulty, you can replace it. Note that if you only have one SSD, you cannot remove it while the firewall is powered on.
Remove one of the SSDs—If you have two SSDs, you can remove one.
Add a second SSD—If you have one SSD, you can add a second SSD and form a RAID.

When you use only one SSD in Secure Firewall devices, the Drive State will show as degraded.

Caution

Do not remove an SSD without first removing it from the RAID using this procedure. You can cause data loss.

Procedure

Step 1

Remove one of the SSDs.

Remove the SSD from the RAID.

configure raid remove-secure local-disk {1 | 2}

The remove-secure keyword removes the SSD from the RAID, disables the self-encrypting disk feature, and performs a secure erase of the SSD. If you only want to remove the SSD from the RAID and want to keep the data intact, you can use the remove keyword.
Example:
```
> configure raid remove-secure local-disk 2
```

Monitor the RAID status until the SSD no longer shows in the inventory.

show raid

After the SSD is removed from the RAID, the Operability and Drive State will show as degraded. The second drive will no longer be listed as a member disk.

Physically remove the SSD from the chassis.

Step 2

Add an SSD.

Physically add the SSD to the empty slot.
Add the SSD to the RAID.

configure raid add local-disk {1 | 2}

It can take several hours to complete syncing the new SSD to the RAID, during which the firewall is completely operational. You can even reboot, and the sync will continue after it powers up. Use the show raid command to show the status.

If you install an SSD that was previously used on another system, and is still locked, enter the following command:

configure raid add local-disk {1 | 2} psid

The psid is printed on the label attached to the back of the SSD. Alternatively, you can reboot the system, and the SSD will be reformatted and added to the RAID.
