Hi Tony,
first of all your ASM instances have to be set up clustered. You need to
access the diskgroups from all
nodes.
To turn a single instance database into RAC you could use rconfig which
will do the job for you.
see chapter D in the os specific 10g Docs
"Oracle Clusterware and Oracle Real Application Clusters Installation
and Configuration Guide for ..."
If you want to do it on your own:
Create undo tablespaces for the other instances.
Create redo log groups for the other threads.
e.g.
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 4 SIZE 100M, GROUP 5 SIZE
100M, GROUP 6 SIZE 100M;
ALTER DATABASE ENABLE PUBLIC THREAD 2;
Parameters that should be set instance specific:
instance_number,thread,instance_name,undo_tablespace.
It is not neccessary to recreate your controlfile!
Nevertherless the error you posted when trying this was related to ASM.
Diskgroup was not mounted.
