Check that the cables of the primary monitoring destination and secondary monitoring destination are connected to the right switch as monitoring destinations in NIC switching mode.
In the following example, the IP address of the monitoring destination HUB is set incorrectly, and therefore the correct monitoring cannot be performed. This may cause unintended NIC switching at the time of the network failure.
Confirmation method
Use the "hanetpoll print" command to check the monitoring destination before checking the network configuration diagram. In the following example, check that the IP address 192.168.10.250 is assigned to the network device to which the primary interface eth0 of the Interface List is connected.
# /opt/FJSVhanet/usr/sbin/hanetconfig print [IPv4,Patrol / Virtual NIC] Name Hostname Mode Physical ipaddr Interface List +-----------+---------------+----+-----------------+---------------------------+ sha0 192.168.10.110 d 192.168.10.10 eth0,eth1 # /opt/FJSVhanet/usr/sbin/hanetpoll print snip..
