In some cases, especially models with slower hardware or flash-based storage, it is recommended to reduce the load during the update by initiating the update via command line.
Step 1. Download the Update from the Barracuda Download Portal
- Go to the Barracuda download portal and download the update or hotfix.
Step 2. Update via SSH
- Verify that the /phion0/packages/ directory does not contain any files such as an older minor release or a patch package. The directory should only contain the kl, os, ph, sa, and tgz subdirectories.
- Copy the update package or patch into the /phion0/packages/ directory on your firewall. The package path and file name must not contain whitespace characters.
Wait for the update to finish. Depending on your system hardware, the upgrade can take anywhere from 10 minutes (on a fast system) to 60 minutes (on a flash unit). The firewall will reboot after the upgrade process.
