If you purchased a new SuperCluster system running release 2.3 or later, your Oracle installer should have already implemented the quorum disk feature as part of the initial installation. You do not have to follow these instructions to manually add quorum disks to database domains in that case.
However, if you have an existing SuperCluster system that was set up with a software version earlier than version 2.3 and your SuperCluster system meets the following requirements:
The SuperCluster system has fewer than five storage servers
The SuperCluster system has at least two database domains
You will have at least one high redundancy disk group
Then you can take advantage of the quorum disk feature by upgrading your software to release 2.3 or later and then implementing this feature manually using the instructions in this chapter. Your SuperCluster system must meet the requirements provided in Software Requirements for Quorum Disk Manager and must be running Oracle Database 11.2.0.4 or above to use the quorum disk feature.
The procedure to add quorum disks varies, depending on the type of database domain or zone that you are adding the quorum disks to:
If you are adding quorum disks to dedicated Database Domains or Database I/O Domains (global zones), then follow the instructions in Add Quorum Disk to Database Domains (Global Zones).
If you are adding quorum disks to zones in dedicated Database Domains or Database I/O Domains (non-global zones), then follow the instructions in Add Quorum Disks to Database Zones (Non-Global Zones).
Once you have completed the procedures in one of those two sections, you will complete the quorum disk configuration process using the instructions in Complete the Quorum Disk Configuration.
