Sophos Firewall SSD firmware upgrade 19 and 20

Sophos Firewall SSD firmware upgrade for a subset of XGS firewall models Sophos Firewall SSD firmware upgrade 19 and 20 .

 

Overview

A firmware upgrade that improves the operational performance of the Solid-State Drive (SSD) used in some XGS Series appliances will be released via hotfix on January 24, 2024. This is a manufacturer-issued update and is recommended for all eligible appliances.

As the SSDs used in any appliance model may change during the product lifecycle, this firmware upgrade only applies to some SSD models that have been used in a subset of the following XGS Series firewall appliances:

  • XGS 116(w), 126(w), 136(w)
  • XGS 2100, 2300, 3100, 3300
  • XGS 4300, 4500

Customers with an eligible appliance will see a banner and an alert in the Control Center of their firewall.

How to get the new SSD firmware

As the process of installing the SSD firmware will involve a short downtime period, the download will be automated, but the installation will require manual intervention. This is to allow you to schedule this update at your earliest convenience. Both steps must be completed:

  1. Automatic firmware download: If you have not changed the default setting*, the new SSD firmware will download to appliances running SFOS 19.0, 19.5, and 20.0 (including the GA and all MR versions), but it will not be installed.
    • If hotfixes are turned off (not recommended), you will need to upgrade to the next SFOS maintenance release (19.5 MR4 or later).
    • SFOS 19.5 MR4 and later will also include the new SSD firmware, and the manual installation process remains the same.
  2. Manual installation: You will need to manually install the SSD firmware via the CLI using the command delivered with the hotfix or firmware upgrade. Please ensure that you complete the installation during a maintenance window to accommodate the short downtime period.

*Allow automatic installation of hotfixes is turned on by default

Note: You can easily verify if hotfixes are turned on. To check, enter the following command in the CLI: system hotfix show

When will the new SSD firmware be available?

On January 24, 2024, the new SSD firmware version will be pushed over the air via a hotfix to firewalls that require the upgrade and are running SFOS versions 19.0, 19.5, and 20.0, including GA versions and all MRs.

Future MRs of SFOS (19.5 MR4 and later) will also include this SSD firmware. For any future release, the manual installation process for the firmware is as described in the article.

How do I know if my firewall needs the SSD firmware upgrade?

Control Center banner, alert, and Email notification: If your firewall is eligible for the firmware update, a banner and an alert message will appear on the Control Center. The firewall will also send out an email notification.

These will only appear if the upgrade is required and hotfixes are turned on.

Alert

SSD: A recommended SSD firmware update is available for this device that improves the performance of the SSD. Upgrade is via the CLI. For details, see xxKBarticlexx.

Expanded alert

If you have one of the above models, have hotfixes turned on, and do not see the banner, your firewall does not need the SSD firmware upgrade.

Additional verification: An easy way to check if your firewall requires the upgrade is to enter the following command on the CLI: system ssd show

The command is only available if hotfixes are turned on.

Planning Requirements

  • Schedule a maintenance window. Installing the SSD firmware involves a short downtime.
  • As a precautionary measure, ensure you have access to power cycle the appliance, should that be required.

Steps to upgrade the SSD firmware

Follow these steps to complete the installation:

  1. Sign in to the CLI console and enter 4 for Device console.
  2. To verify if the upgrade is available, enter the following command:
    system ssd show
    You will see the details if an upgrade is available.
  3. To upgrade the SSD firmware, enter the following command:
    system ssd update
    The command upgrades the SSD firmware and immediately restarts the firewall. This results in a short downtime period.

Caution: The installation process will automatically interrupt the power supply and restart the appliance. In isolated instances, if the appliance does not restart within a few minutes (maximum 10 minutes), you may need to manually power cycle the appliance.

How to perform a power cycle?

Switch off the power, wait for two minutes, then switch it on again.

If the appliance is connected to a secondary or redundant power supply, switch off both the primary and the secondary power supplies to ensure a full power cycle. A redundant power supply unit can interfere with the upgrade process by increasing the hold-up capacity of the box. Sophos Firewall SSD firmware upgrade 19 and 20

Other firewall deployments

High availability

In an HA cluster, you must upgrade the SSD firmware on each appliance individually as follows:

  1. Verify if both appliances in the cluster require the SSD upgrade (see information above). Appliances in an HA cluster will not always have the same SSD model.
  2. If both require the upgrade, upgrade one appliance first.
    After it restarts, upgrade the second appliance.

AirGap

The new SSD firmware and the CLI commands will be released in the following maintenance releases:

  • 20.0 MR1 and onwards
  • 19.5 MR4 and onwards

After you upgrade to one of these MR versions, the banner and alert message on the Control Center will appear if the upgrade applies to your appliance. If you see the banner/alert, follow the instructions above and use the CLI command to install the firmware manually.

Frequently asked questions

 

Google Chat New Features, iiQ8 info

 

 

  • Q: Why do I need to upgrade the SSD?
    A: The upgrade improves the overall SSD performance and is recommended for all eligible appliances.
  • Q: What if I don’t immediately update the SSD? Does it impact the firewall?
    A: The new SSD firmware versions improve the operational performance of the SSDs used in some Sophos Firewall appliances. Your Sophos appliance will not be immediately impacted if you continue operating with the older SSD firmware; however, we recommend updating the SSD firmware at your earliest convenience to ensure optimal SSD performance.
  • Q: Why do I only see an upgrade available for some XGS models?
    A: The manual SSD firmware upgrade only applies to a subset of the XGS appliance models listed above. This depends on which SSD model is used. Sophos Firewall SSD firmware upgrade 19 and 20For other firewall appliances and SSD models, the SSD firmware update doesn’t require any manual intervention or a restart. We’ve been working to make this process as seamless as possible. For example, we delivered an automated SSD firmware update in 19.5 MR3.
  • Q: Does the upgrade require the firewall’s power to be switched off and back on?
    A: Only in very isolated instances. In most cases, the system ssd update command will update the SSD firmware and restart the firewall after the process is complete.If your appliance does not restart within a few minutes (maximum 10 minutes), switch off the power, wait for two minutes, then switch the power on again.
  • Q: If the firewall doesn’t restart after the upgrade, and I can’t switch the power off and back on, how can I recover the firewall?
    A: If you do not have access to switch the power off and back on, we recommend that you wait to upgrade the SSD firmware. Schedule the upgrade when you have access to the power controls. This is a necessary precaution.
