Reference IP:
Enable Reference IP Checking – Select this option to enable reference
IP checking. A Reference IP is an IP address that the
proNAS HA service will check when the heartbeat channel(s)
between the two servers are lost. This IP will be used as a
reference point to device whether the network really has a
problem before doing failover or takeover. HA will ping the
local and virtual IP address of proNAS, and for any reason
that this fails, HA will ping this reference IP as a double
check. If ping still fails, proNAS HA will proceed with failover
or takeover. The IP of a router or any network device which
is always online can be used as a Reference IP.
IP Address – Enter the IP address of the Reference IP to check the
availability of the servers.
