[. . . ] · Test RAM Evokes a RAM checking utility. Note that not the whole existing RAM can be tested as ART OS occupies some RAM by itself. · System recovery Effectively invokes a reinstall of the appliance. For hard disk based appliances, an installation "*. iso" image as well as a backup PAR file are stored within a dedicated partition on the hard drive and will be used. Optionally, an *. iso image on an USB thumb drive connected to the appliance may be used. If no PAR file is available, the default installation for the corresponding appliance type is chosen. See also Performing a Recovery Process, page 15. For flash-only appliances, this option always requires an USB thumb drive connected to the system. The system will be recovered either to the release version of Barracuda NG Firewall it was first installed in, losing the updates installed since then, or to the state stored in a PAR file residing within the art partition of the system drive. Once your appliance is readily configured, you may save the configuration for ART recovery through Box > Active Recovery > Save Current Config. This will generate an ISO file within the art partition that will be used during the next recovery process. ART system recovery only works if the appliance was installed with Barracuda NG Firewall 5. 0. It is not possible to use ART system recovery on systems that were updated from 4. 0 or 4. 2. See Using ART Recovery without USB Stick, page 15, in order to learn about the ART recovery process. · Configuration reset Allows the definition of a new host name, management IP address, default route and optionally a network driver. This functionality comes in handy if connectivity to an appliance was lost due to some misconfiguration or activation of an erroneous PAR file. · Start shell Enables access to a bash shell within which you may perform certain commands included with ART. · Reboot Reboots the appliance into Barracuda OS. · Exit Exits into Barracuda OS. Currently the only possible reason the ART recovery OS is invoked automatically for is a hard disk drive flagged as "dirty". This may indicate a hardware failure or a corrupt file system on the hard disk. The latter might be remedied by an administrator through the shell via a remote login. 14 Appliance Installation Guide ART and Central Management Appliances that are centrally managed using a Barracuda NG Control Center will obviously no longer be normally centrally manageable once the recovery system is up and running. However, ART is aware of the appliance being centrally managed and therefore invokes a connection back to the Control Center, indicting its presence. An administrator can then login remotely to the appliance using SSH, invoking the ART menu or a command line in order to debug the problem or perform a recovery process. Performing a Recovery Process See the Barracuda NG Firewall Administrator's Guide in order to learn about creating Portable Archive (PAR) files. Using a PAR file on an USB Stick · · Be sure that the appliance is powered off. Then, insert the USB stick into one of the USB connectors of the appliance and switch the appliance on. [. . . ] A Control Center managed box running in ART mode cannot be managed through the CC, although it will build a connection to the CC signalling its presence. See Installation and Recovery Using ART, page 13 in order to get in-depth information about Active Recovery Technology. 21 Using LCD Display and Keypad F800 Rack Mount Installation Verify that the kit is complete, as shown here.
