Symptoms

After creating a new sync-failover device group without network failover enabled, both devices remain Active.

Impact

Both device in the HA pair will be Active, which is unlikely to pass traffic successfully.

Conditions

Create a new sync-failover device-group without enabling network failover.

Workaround

After adding the 2nd device to the sync-failover group, restart sod with "bigstart restart sod" on both devices.

Fix Information

After creating the sync-failover group with without network failover configured, but a serial failover cable installed, one of the devices becomes Standby and the other remains Active.
