  Thanks to all those who replied, maybe i was not clear in my original email. 
   
  Basically all i want to be able to do is stop the CRS daemon on nodes 1 and 3 
(so the instances on these nodes will be single RACed instances) and also have 
the CRS daemon running on nodes 2 and 4. 
   
  I know i can do something like init.crs on the nodes i want to stop the CRS 
daemon (nodes 1 and 3)  
   
  Do I have to shut down all the instances beforehand before i can issue the 
init.crs stop? 
   
  Will the other instances on nodes 3 and 4 still be under CRS control?
   
  TIA

  Scenario.
   
  currently i have a number of RACed databases (3 in total) which are running 
10g RAC on a 4-node (say node 1, node2, node3 and node4) TRU64 Cluster. 
   
  what i want to be able to do is take 2 of these databases out of RAC mode (on 
node 1 and 3 and leave the third database RACed (on nodes 2 and 4)
   
  Is this possible, if so can someone give me some pointers on how. 
   
  My specific question are, do i have to de-install the RAC software and CRS 
software on the nodes which are not going to have the RAC databases, but my 
ORACLE_HOME and CRS_HOME are on a shared filesystem, so i guess this can't be 
done! 
   
  Am not using ASM.
   
  TIA
