How do I do this if I already have a single instance db running on ASM from GRID_HOME on an existing node and just want to convert the existing instance to a RAC instance on the existing node and then add a second node with a new second RAC instance which has the shared ASM mounted.

Forgot to add, version of Oracle db and GRID software is 11.2.0.3.2
