This suggests that you are using Rocks.

In short, you need to use the remove or delete host argument to 
insert-ethers.  Basically Rocks captures MAC addresses, and then 
associates specific names and IPs with these MAC addresses.  This is 
done in the database.  It is (sadly) easier to re-install the compute 
node than it is to fix the databases.

Your steps to fix it

a) remove the host "insert-ethers --remove ..."  (look up the exact syntax)
b) remove the network-0-0.local (same way as above)
c) re-insert the host "insert-ethers --cabinet 0 --rank 7"
and select compute node.  Force the compute node to re-install.

and you should be done.
