12.1.2.3.0 Exadata - Quorum Disks - Increase the availability of your Voting and CRS Files

If you have a QH of EH and want to increase the availability of your voting and css files, you can do so by multiplexing them in DB Nodes using a new feature called QUORUM Disks.

All the steps necessary are described here:

They are done using the quorumdiskmgr found at /opt/oracle.SupportTools
