Here are the commands to rename a Celerra CIFS server:
 
Be sure putty session has a lot of lines of scroll back set so you can scroll up to see previous commands/results
 

Login to console as “nasadmin”.

 
testserv - Original server name
testservnew – new server name
 
get existing CIFS server data:
> server_cifs server_2
> server_cifs server_3
 
 
1. Unjoin the original compname from the domain, type:
server_cifs server_2 -Unjoin compname=testserv,domain=contourds.local,admin=adadmin
 
2. Delete the compname from the CIFS configuration of the Data Mover, type:  
server_cifs server_2 -delete compname=testserv
 
3. Add the compname back to the CIFS configuration of the Data Mover as a NetBIOS name, type:
server_cifs server_2 -add netbios=testserv,domain=contourds.local,interface=192_168_191_65
 
4. Rename the NetBIOS server to the new name, type:
server_cifs server_2 -rename -netbios testserv testservnew
 
5. Delete the renamed NetBIOS name from step 4. from the CIFS configuration of the Data Mover, type:
server_cifs server_2 -delete netbios=testservnew
 
6. Add the new compname to the CIFS configuration and active directory (AD) domain, type:
server_cifs server_2 -add compname=testservnew,domain=contourds.local,interface=192_168_191_65
 
7. Join the new compname to the CIFS configuration and active directory (AD) domain, type:
server_cifs server_2 -Join compname=testservnew,domain=contourds.local,admin=adadmin
 
That's it!
