Long story short, just get a TZ 670 HA unit (different SKU, no license needed) and do the exact cabling for the 2nd unit. Add the S/N of the secondary unit in the HA configuration and you are done (additional steps can be necessary).

Optionally you can buy a stateful HA license for your primary unit, this makes the failover a bit smoother.

TZ 670 HA unit (different SKU, no license needed??? Do you mean for HA we just need license for primary sonic wall?? While for secondary no need of license? Secondly all configuration necessary on primary sonic only? OR there is bit configuration in secondary too?

I have one tz670 connected with one Cisco switch as per your words for secondary connect the same cable. Is there need of other Cisco switch for secondary sonic?

If you only have one LAN switch then that becomes a single point of failure, so you could add another switch.
