Hi Everyone,
I have run into an issue with my SCVMM Implementation. I forgot to change (and did not know about) the default MAC Address pool in two SCVMM Implementations:
2012 R2
2016
Today I had my first overlap, where a new VM could not ping certain machines on the network. Tracked it down to a duplicate MAC address, that was already in use by another VM - on the other SCVMM host cluster.
Is there a way I can modify the MAC address ranges without a major outage? I shrank the MAC Address Pool on the 2012R2 side, which worked.
However when I attempted to modify on the 2016, some of the MAC addresses are already assigned to machines. I would rather not have to shut shut the VM's down (I am guessing if I do that I have to detach the NIC, make my changes, and then attach the NIC again - which will require a shut down).
Thanks.
