Use the following script to manually assign IPs on each node for each of the SMB interfaces.

#Login to the host console of each system using iDRAC Virtual Console and assign host IPs and respective VLANs
#This step is not needed if you have DHCP in your environment. Ensure the hosts are assigned IPs in the correct VLAN.
