Harel is executed after bringing the CRS down and then will bring the CRS up. Also  selecting more Node for Install require to bring the CRS down on all nodes and hence the Remote copy might surely have constraint to stop CRS otherwise any Library open might conflict especially on AIX where you need to run sliblclean at each steps to avoid the conflict

The reason is that it will take 15 Minutes to upgrade on Node 1 and then 15 minutes to copy to other nodes. If there are 7 more nodes, then it will take 15*7=100+ min. to copy to other nodes. So I f will run seperately from each nodes, it will be total of 15-20 minutes for Software and then 15 minutes for
