A new disk group can be created using the extra 1 TB of disk space. For example, if the existing disks are 3 TB, and the additional disks are 4 TB, then it is necessary to create grid disks that match the size on the 3 TB disks. When adding the same type of disk, ensure that the grid disk sizes are exactly the same even if the new disks are larger than the existing ones. For example, if the existing disk groups all use high performance disks, and cells with high capacity disks are being added, then it is necessary to create new disk groups for the high capacity disks. The cellip.ora file on a database server should only include the IP addresses for the Exadata Storage Servers used with that database server.Ĭells with disk types different from what is already installed can be added, but the disk types cannot be mixed in the same Oracle ASM disk group.
When Oracle Exadata Database Machines run in separate clusters, do not modify the cellip.ora files. infinicheck -c /tmp/combined_cellip.ora -b # cd /opt/oracle.SupportTools/ibdiagtools The following is an example of the commands: You need to create a file that contains IP addresses for Exadata Storage Servers, such as combined_cellip.ora. After modifying the network, run the verify-topology and infinicheck commands to verify the network is working properly. Failure to do so causes duplicate IP addresses. You must modify the IP addresses before re-configuring the InfiniBand network. When Oracle Exadata Database Machine is deployed, the default InfiniBand network is 192.168.10.1. If you are planning to use multiple Oracle Exadata Database Machines in this manner, then note the following:Īll servers on the InfiniBand network must have a unique IP address. Multiple Oracle Exadata Database Machines can be run as separate environments, and connect through the InfiniBand network. There should be one disk group for the drives in the Oracle Exadata Database Machine Eighth Rack rack and one disk group for the drives in Oracle Exadata Storage Expansion Rack.
When extending Oracle Exadata Database Machine Eighth Rack with Oracle Exadata Storage Expansion Rack make sure that there are two separate disk groups. Only optical cables are supported for lengths greater than 5 meters.Įarlier Oracle Exadata Racks can be extended with later Oracle Exadata Racks. If the racks are not adjacent or use overhead cabling trays, then they may require longer cables lengths. The cable lengths shown in Multi-Rack Cabling Tables assume the racks are adjacent to each other.
