1.8 Preparing the Network Configuration

When adding additional servers to your rack, you will need IP address and the current network configuration settings.

When adding additional servers or rack to an existing rack, the IP addresses for the new servers are obtained using Oracle Exadata Deployment Assistant (OEDA). If adding additional servers to an existing rack, then the application should only include the new servers. If adding an additional rack, then the new rack should use its own OEDA. The exact Oracle Automatic Storage Management (Oracle ASM) disk group configuration currently in use may not be reflected by the application. This is not an issue, as the grid disks and disk groups are configured manually. All other items, such as the Oracle home location and owner, should be defined exactly as the existing configuration.

When adding Oracle Exadata X4-2 Database Server or later or Oracle Exadata Storage Server X4-2L or later, the bonding configuration must match the existing servers in the rack. The OEDA InfiniBand configuration page has an option to select the type of bonding. Select the option for active-active bonding, or deselect the option for active-passive bonding.

If you want to configure network isolation for groups of virtual database servers and storage servers so that network traffic of one Oracle RAC cluster is not accessible to another Oracle RAC cluster, then you can use OEDA to configuration InfiniBand Partitioning.

The configuration file generated by the application is used by OEDA. After using OEDA, use the checkip.sh and dbm.dat files to verify the network configuration. The only errors that should occur are from the ping command to the SCAN addresses, Cisco switch, and Sun Datacenter InfiniBand Switch 36 switches.
