Verify Exadata Storage Server Disk Space for Additional Zones

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.

1. Determine the amount of free space available on the Exadata Storage Servers:

   CellCLI> list celldisk attributes name,freespace,freespacemap

   You should see output similar to the following:

   CD_00_etc25celadm01     366.6875G     ((offset=162.046875G,size=366.6875G))

2. Look at the CD_number entries to determine the amount of available space on each of the Exadata Storage Servers.
3. Use the information on the amount of available space on each of the Exadata Storage Servers to determine how much space you can use for the disk groups for each new cluster you are creating for the new zones.

   You need enough space for these disk groups for each new cluster that you are creating:

   • DATA

   • RECO

   • DBFS (if necessary)

4. Create the configuration files using OEDA.
