3.3 Setting up a New Rack

A new rack is configured at the factory. However, it is necessary to set up the network and configuration files for use with the existing rack.

1. Configure the new rack and servers as described in Configuring Oracle Exadata Database Machine in the Oracle Exadata Database Machine Installation and Configuration Guide.

   Complete the appropriate tasks to configure the rack and its components, but do not complete the task for installing the Exadata configuration information and software on the servers. This task will be completed later in this procedure.

2. Verify the time is the same on the new servers as on the existing servers. This check is performed for storage servers and database servers.

3. Ensure the NTP settings are the same on the new servers as on the existing servers. This check is performed for storage servers and database servers.

4. Configure HugePages on the new servers to match the existing servers.

5. Ensure the RDMA Network Fabric and bonded client Ethernet interface names on the new database servers match the existing database servers.

6. Configure the rack as described in Loading the Configuration Information and Installing the Software in Oracle Exadata Database Machine Installation and Configuration Guide. You can use either the Oracle Exadata Deployment Assistant (OEDA) or Oracle Enterprise Manager Cloud Control to configure the rack.

   Note:

   • Only run OEDA up to the Create Grid Disks step, then configure storage servers as described in Configuring Cells, Cell Disks, and Grid Disks with CellCLI in Oracle Exadata System Software User's Guide.
   • When adding servers with 3 TB High Capacity (HC) disks to existing servers with 2TB disks, it is recommended to follow the procedure in My Oracle Support Doc ID 1476336.1 to properly define the grid disks and disk groups. At this point of setting up the rack, it is only necessary to define the grid disks. The disk groups are created after the cluster has been extended on to the new nodes.
   • If the existing storage servers are Extreme Flash (EF) and you are adding High Capacity (HC) storage servers, or if the existing storage servers are HC and you are adding EF storage servers, then you must place the new disks in new disk groups. You cannot mix EF and HC disks within the same disk group.

7. Go to Setting User Equivalence to continue the hardware configuration.
