Root.sh failed when adding a new node

We  are adding a 3 rd node to our 2 node cluster on Linux 11gR2 RAC.   The addnode.sh ended without any error. The execution of the root.sh failed with errors saying failed to create a new disk group. Couple questions:

1. The 3rd node is supposed to share the same disk group with node 1 and 2. Why does it create its own disk group?

2. The olsnode  command on node 1 says the cluster has 2 nodes which are node 1 and 2 . On node 3 says node 3 is the only node in the cluster. So something went wrong and node 3 is now on its own cluster.

3. I ran addnode.sh from node 1 and it copied the files to 3 rd node. When root.sh is executed on 3 rd node, it started an ASM instance called +ASM1. shouldn't it be +ASM3?
