when adding another fibre nic to host esxi 4.1, it is changing vmnic numbers

I added another fibre nic to the host and when it booted up it moved some of the vnic numbers from exsiting nics went to the ports on the new fibre card, which in turn caused some of the vnics that were on those numbers to show disconnected..
How can I resolve this so I can add the new fibre nic?

This is completely normal, when you ADD a new interface, the host will assign vmnic numbers and assignments, based on the location of the PCI card on the BUS.

It cannot be undone from the host configuration.

It could help to remove the interface card, and try another PCI slot.

I don't have any other slots available...
What about this article from VMware?
Have you ever done this??

this can work "sometimes", it worked better with ESX.

You can certainly try, but it may be quicker to re-assign vmnics to vSwitches, than editing configuration using SSH/vi at the console, and restating the host.

So are you saying once I added the new nic and it changes my vnics around, to just change them back to what they should be?
I was just going to follow the article from steps 1-10

yes, if you want to alter your nics, to what they were you will need to try and modify the configuration.

if the order concerns you, otherwise just re-arrange you vSwitches.

So just to make sure I understand, if I have vnic 12 assigned to vswitch 1 and the new fibre card takes vnic12, should I see another vnic number available to swap out with the old vnic 12?

you will notice the numbers have probably increased

so vmnic12 is the new fibre card (possibly), but you may have a vmnic13, you will need to check the PCI device ID to vmnic mapping file.
