The high level steps to prepare the target system include:
1. Create volumes in the Compellent storage and map to the target servers (PowerEdge R720).
2. Perform zoning in the Brocade switches to associate the Dell PowerEdge R720 servers’ WWN’s with
the Compellent front-end ports WWN’s.
3. Create volume partitions on the two PowerEdge R720 servers.
4. Configure DM Multipath to the volumes on the two PowerEdge R720 servers.
5. Stamp the volumes as ASM disks on the two PowerEdge R720 servers. Again, ASM disks need to
have different names as the source database or data migration does not work later. The screen
output of the service oracleasm listdisks command is shown below.

6. Install Oracle RAC Clusterware 11.1.0.7 on the two PowerEdge R720 servers.
7. Install Oracle Database 11.1.0.7 binary on the two PowerEdge R720 servers.
8. Use the Oracle tool Database Configuration Assistant (DBCA) to create the Oracle ASM instance
without creating the database instance. In Oracle release 11.1.0.7, the creation of the ASM
instance and the creation of the database instance are combined in the DBCA tool. Once ASM
