We have connected additional interfaces to our FAS8040 running ontap 9.3P5
These new Interfaces are connected to 10G Ethernet switches the old ones are just 1G and connected to different switches but physicially its the same network of a large environment.
I created a new LAPC ifgroup and added the new ports , created vlans on the new ifgrp added them to the broadcastdomain ( each vlan has its own) and and migrated all interfaces.
Since I have added ports from different ifgroups into one broadcast domain I get periodically the following error in my event logs:
ERROR vifmgr.bcastDomainPartition: Broadcast domain <BCDOMAINNAME> is partitioned into 2 groups on node <NODENAME>. The different groups are: {a0a-<VLANXY>}, {a0b-VLANXY}. LIFs hosted on the ports in this broadcast domain may be at the risk of seeing connectivity issues.
Its not clear to me why this is an error or might be a problem, obviously it seems to be a problem if ports from different ifgroups are added to the same broadcast domain?
Can someone help me to understand the trouble this might cause?
And if its an error why is it allowed to create such a configuration?
Thanks
