How to determine and setup IP, MAC address in both physical and virtual machines
Posted on 2011-05-08
Developing a small production datacenter and as we deploy virtual machine after machine, we're getting the knack for P2V and now looking to wholesale virtualization of entire enterprise as part of modernization (ERP system is running on HPUX 10.2 from ~1994.) All the backstory to reinforce that in general we're good at keeping systems healthy and recovering from disaster and getting good at virtualization. The more we know the more we go for.
The problem/question as we start hardening up the new server farm (more like patio garden for some but big to us); how do we access and know what all the physical and virtual IP and MAC address informationnis?
We'll have pieced together as many as 10 physical servers and an NAS storage unit and most of them have two NIC's apiece; then many of the virtual machines were physical conversions and they have networking "memories" of their physical self and then virtual NIC's added during P2V process.
Bottom line is we're grappling with how to apply physical NIC, MAC & switch thinking in our new virtual world and in several instances we can't get virtual machines to connect normally outside their new environment. Is there or is there a better way to know and/or static assign physical IP and MAC and virtual IP and MAC assignments in all cases?
