Before beginning the process of creating additional zones on existing Database Domains with zones, you must first verify that you have the appropriate amount of disk space available on the Exadata Storage Servers:
If you are not sharing Exadata Storage Servers across clusters and you have entire Exadata Storage Servers available for the additional zones that you are adding to the existing Database Domains with zones, then you do not have to do anything more here. You can assign the entire Exadata Storage Servers to the new zones as part of this procedure.
If you are sharing Exadata Storage Servers across clusters, you must determine how much free space is available on the Exadata Storage Servers that you are using for these new zones before proceeding.
CellCLI> list celldisk attributes name,freespace,freespacemap
You should see output similar to the following:

You need enough space for these disk groups for each new cluster that you are creating:
DATA
RECO
DBFS (if necessary)
