IPMP MAC address license limitation
Hi blowtorch, prowla--
Thanks for the prompt input! I plan on using IPMP. As I said before, I can guarantee that each NIC is plugged into a seperate switch and each switch has a dedicated patch panel. They both plug into the same router but that is less likely to be a problem since it is a high-end cisco that is completely modular.
I forgot to mention in my post why it is so important the NIC's MAC address failover also. My companies software is licensed by MAC address. I need to change the MAC address on failover to avoid invalidating the softwares license. I have done extensive research on IPMP but have yet to find a solution to my dilemma.
Although this system requires high availability, I have no problems with a delay in the failover. The users would only have a slight hiccup in the system instead of downtime, me being dispatched, bringing up the second ethernet, and requesting a new license (which could take near a day).
My thought is to configure IPMP so that the primary NIC holds the primary IP and licensed MAC address. The secondary NIC will use a IP (unknown to everyone) on a separate subnet and using a separate MAC address. On failure of the primary NIC, the primary NIC will failover to a unique IP/MAC on the private subnet. The secondary NIC will then attain the public IP/subnet and licensed MAC address. On recovery everything should fail back to the original configuration (if possible--haven't seen info on this).
Any ideas how something like this can be done? I've yet to find any documentation/examples on this topic.... I'm sure very few people require this type of failover.
Anyways, I know this one is probably a stumper... again thanks for your input
prowla-- I have considered all(most) points of failure. We had JBOD disks serving medical images. These have been replaced with dual-path dual HBA SAN attached RAID 5 disks. I also tested our SAN-attached 17TB longterm archive's failover procedure and found that the Veritas DMP was not operating as expected. Basically the mounted filesystem just went
.... I was able to find the error in configuration and resolved that. I'm sure there are more single points of failure. I just haven't found or thought of them yet!
