Hi Ricky,

Yes, there is more to it than just changing the NIC cards themselves.  Here is the basics,

Private NIC changes needed:

* The LLTTab file on the server contains the MAC addresses of the private NIC when configured for LLT of ethernet.  The server where the NIC is changed will need to have the MAC address changed to the new MAC and restart LLT/GAB and HAD with the following process.

1. Perform these steps after replacing the NIC and correcting the MAC address in the LLTTab file.

2. at a command prompt run the following commands in order.

   hastop -local -force

   net stop llt /y

   hastart

Public NIC changes needed:

This gets a little more involved depending on the configuration of the cluster.  Each NIC and IP resource configured in the cluster has a copy of the public NIC MAC on each server.  You will need to modify each NIC and IP resource to have the correct MAC address for the server where the NIC adaptor was changed.  The good news is that this only needs to be done on 1 node in the cluster since the configuration is shared between all nodes.  Just make sure that you save and close the configuration when done making these changes.

If you need assistance with making these changes to the cluster configuration please open a Symantec Technical Support case.  We will be glad to assist you in getting your cluster configuraiton back to a proper running state.

Thank you,

Wally
