Re: MAC Address changes during SG Migration
This is normal.
The floating IP address is a second virtual IP address that runs on the the same hardware (network card) as another IP on the system.
When the package is running on node A it gets a MAC address from node A. If its running on node B it gets the MAC address from node B.

Re: MAC Address changes during SG Migration
What is your network interconnect module?
When the MAC address changes, the network stack should send out a Gratuitous ARP, which lets the other devices on the network see the new MAC/IP combo and update or clear their cache entries.
In normal SG environment, when you move a Service Guard package, the VIP arp cache entry is immediately cleared on other servers on the network (not just other nodes in the cluster).
You say that other VMs in the other local blades have:
>No ping, telnet, ssh, ftp, sftp. No communications whatwoever.
When a 'ping', for example fails, is it the case that the arp cache has NO entry for the IP, or that it still has the OLD entry with OLD MAC address?
When you add the arp entry manually, are you using the "temp" argument?
If not, then the entry will be permanent.
So, perhaps you've built up a bunch of permanent entries that are now not changing normally?
