    rename asm instance in RAC

    Sahar
      Hello,
      ClusterWare 11.2.0.3 + RAC db same version .
      I need to rename one of the ASM instances

      How can this be done ?

      the situation is as follows , I needed to take one of the server out of the cluster and then bring him back in .
      when I have added him , he got a new ASM instance name (was ASM1 now it got ASM3 , 2 node rac) ,


      thanks

            HI,
            i have seen this already ,
            I am looking for a way to do this in a rolling manner
            meaning not to shutdown the whole cluster but node after node while there is always one node up an running with an active db instance


            thanks

              That is not possible !!

              That is like renaming a file system with a database running on it.
              It's like "I want to replace the wheels of my car, but I want to keep driving while doing it..."

              How would you ever imagine that this would work, when the "changed" node comes back online and starts interacting with the node still running?

                I'm not 100% sure about doing it online but I think, it's possible. What if a node in a RAC is corrupted or failed. We can delete a node from a cluster and add a new node.

                  No you don't. Supply reasons and justification for wanting to changes the SID of an ASM instance,
                  the situation is as follows , I needed to take one of the server out of the cluster and then bring him back in .
                  when I have added him , he got a new ASM instance name (was ASM1 now it got ASM3 , 2 node rac) ,
                  So? What is wrong with an instance called +ASM3 in a 2 node RAC? How does that now reduce and impair cluster functionality?
