Updating HA-Synced Units or HA-Synced NG Control Centers

In the instructions below, the term "primary unit" refers to the unit used for regular operation, while "HA unit" refers to the secondary unit used as a failover system.

For Firewall and Configuration HA synchronizing, the primary and the HA unit must both run at least firmware release versions between 4.2.11 and 5.0.3.

Barracuda Networks strongly recommends to follow the procedure for updating HA systems exactly as described below in order to minimize any operational drop outs.

Step 1: Prepare the HA Unit

•Log-in to the HA unit using Barracuda NG Admin.

•Block the (standby) server on the HA unit within Control > Server.

Step 2: Update the HA Unit

•Update the HA unit using SSH as delineated in Updating Units or NG Control

Centers Using SSH, page 15.

No more interaction with the HA unit is necessary. Wait until the update is finished. Depending on the hardware, it will need from 15 minutes on the fastest appliances up to 60 minutes on the flash

appliances.

Do not interrupt the update procedure. During update, the unit boots several times and due to this, the connection will be terminated. Indicators that the update process has been finished are the following output on the console: Barracuda NG Firewall release 5.0.3-xxx, or the operativeness of logging in again using SSH or Barracuda NG Admin.

Step 3: Switch Servers to the HA Unit and Prepare the Primary Unit

•Log-in to the primary unit using Barracuda NG Admin.
