Checking High Availability Status

This screen summarizes the status of the high availability pair.

High Availability Status

High Availability Status

• Status — Indicates Primary or Secondary and ACTIVE or STANDBY.
• Primary State — Initial configuration.
• Secondary State — Secondary configuration.
• Active Up Time — Indicates how long the current Active firewall has been Active, since it last became Active. This line only displays when High Availability is enabled. If failure of the Primary SonicWall occurs, the Secondary SonicWall assumes the Primary SonicWall LAN and WAN IP addresses.
• Found Peer — Indicates if the Primary unit has discovered the Secondary unit. Possible values are Yes and No.
• Settings Synchronized — Indicates if HA settings are synchronized between the Primary and Secondary units. Possible values are Yes and No.
• Stateful HA Synchronized — Indicates if stateful synchronization settings are synchronized between the Primary and Secondary units. Possible values are Yes and No.

High Availability Configuration

• HA Mode — One method to determine which SonicWall instance is Active is to check the HA Settings Status indicator on the DEVICE | High Availability > Settings page. If the Primary SonicWall is Active, the first line in the page indicates that the Primary SonicWall is currently Active. It is also possible to check the status of the Secondary SonicWall by logging into the independent LAN management IP addresses of the Secondary SonicWall. If the Primary SonicWall is operating normally, the status indicates that the Secondary SonicWall is currently Standby. If the Secondary has taken over for the Primary, the status indicates that the Secondary is currently Active. In the event of a failure in the Primary SonicWall, you can access the management interface of the Secondary SonicWall at the Primary SonicWall LAN IP address or at the Secondary SonicWall LAN IP address. When the Primary SonicWall restarts after a failure, it is accessible using the third IP address created during configuration. If preempt mode is enabled, the Primary SonicWall becomes the Active firewall and the Secondary firewall returns to Standby status.
• Control Link — Indicates the port, speed, and duplex settings of the HA link, such as HA 1000 Mbps full-duplex, when two firewalls are connected over their specified HA interfaces. When High Availability is not enabled, the field displays Not Configured.
• Data Link — Indicates the port, speed, and duplex settings of the HA link, such as HA 1000 Mbps full-duplex, when two firewalls are connected over their specified HA interfaces. When High Availability is not enabled, the field displays Not Configured.

High Availability Licenses

• Primary Stateful HA Licensed — Indicates if the Primary appliance has a stateful HA license. Possible values are Yes or No.
• Secondary Stateful HA Licensed — Indicates if the Secondary appliance has a stateful HA license. Possible values are Yes or No. The Stateful HA license needs to be activated on both the primary and secondary firewalls separately, they are not shared. You must access MySonicWall.com while logged into the LAN management IP address of the Secondary unit in order to synchronize with the SonicWall licensing server.
