I am not (and cannot be) near the last production cluster. So please
answers for inaccuracies and the such.
YMMV etc. apply
Let me get this straight:
1. You have a data network bond device of two MACs, 1 IP (not the
cluster VIP, node host IP)
2. You have a "management" network of ILOs and IPMIs (actually a
Single point of failure for a given box)
3. You have a third network, let us say power network consisting only
of Electrical Power fencing devices .
each one can be a VLAN perhaps if you have access to the networking pieces.
If necessary, Inter VLAN routing may be used But highly unavisable.
Keep the Data and Management/power vlan very very separate. If
Have got it right?
