Yes, the X0, X1 and X2 interface settings can be amended on the primary device and these
new settings will be copied to the backup device.
Can the synchronization status between the devices be viewed in the management
interface?
Yes. These can be viewed on the Active SRA in the Log > View page. The log message:
"Finish synchronizing all data", will appear.
Is there any provision to make sure that the backup device is working correctly?
Yes. There will be many messages on the Log > View page regarding Active and Idle device
transitions.
You can check the High Availability page for the device status; one should be ACTIVE and
the other will be IDLE, as indicated in the image below:
If the LAN and WAN monitoring IP addresses are configured in the Network Monitoring
Address section, the status of those interfaces is displayed.
You can also check the Network > Interfaces page for the X3 interface status, this should
be "HA Link-Connected".
Are firmware and settings synchronized to the Idle unit?
Yes, both firmware and settings are synchronized between Active and Idle nodes. The
Synchronize Firmware button allows you to synchronize firmware from the Active to the Idle
unit. When settings are changed, clicking the Accept button synchronizes settings.
Does the HA configuration for SRA 4200 or 4600 devices differ from the HA configuration
of Dell SonicWALL firewall devices?
Yes. HA configuration on a firewall is very different. Along with other items, firewall HA is
also available in Active/Active state and can be assigned a virtual IP address. HA with SRA
devices is currently available only in Active/Passive mode.
How are settings applied to the Idle device?
Settings from the Active device are copied over to the Idle device as soon as HA
configuration is complete. You can check the success of this in the active device logs.
What happens to the backup device settings?
The backup device settings are deleted and replaced with the primary device settings. If
you wish to keep any settings from the backup device, it is recommended that you
download a backup of the settings before switching to HA.
