After installing several dozen clusters on redhat 4 and 5 I can tell you that at least with Linux this isn't the case. You run the installer (and the copy) with the cluster up on all the nodes and then run one by one.

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 Sanjay

About 2, Since the installation and copy of the CRS is done with the CRS up an all the nodes, I believe you can do that before the down time window and then run in the window.

I had to upgrade one of the 8 Node RAC environment and it is running 5 Database with ASM and RDBMS with it own Home in on AIX. We have only 2-3 hrs window and so want to have expert opinion on the following

  1. If I will upgrade CRS and it suggest at the end of successfull install to run * on all NODES* Can I run on all node in parallel. It takes 10-15 minutes and so want to save some time. Not clear if it affect each other as anyway CRS is down at that time on that node
  2. Can I run the CRS upgrade indiviual on all node at the same time from few new putty session instead of initiating from one window and selecting all nodes. 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
  3. If CRS is upgraded and is down, Can I start the ASM and RDBMS upgrade at the same time or it will conflict due to /tmp/installer Lock files or any other issue can come.
