The heartbeats NICs are lan901 and lan902.
I know VCS heatbeats are broadcast packets. and LLT on each system in the cluster sends heartbeat packets out on all configured LLT interfaces every half second.
My questions are:
1) How, by what mechanism, does VCS check IF different heartbeat NICs are in same network (VLAN)?
To which kind of address (MAC or OS device names) does the check signals send?
2) How often does it check if NICs are in same VLAN?
3) We have other systems Cluster-B and Cluster-C, they have almost the same network configurations (To be verified), but their syslogs do not have these kind of warnings.Why?
Thanks in advance!
