VSA cluster host to have motherboard replaced including integrated NICs. Any Gotchas?

Hi,

One of the hosts in our cluster is to have the motherboard replace on Monday. The fault is with the idrac so the host is still more or less working and is still in production until then

I am concerned that the integrated network interfaces on the mb are used for VSA and HA clustering will be changing. Do I need to do any preparatory work in regard to this, or any post-swap config before returning the system back to production after the swap-out?

We have VSA 5.1 running on Esxi 5.5

Thanks,

Pip.
