New white paper on Veritas Cluster Server I/O Fencing! 

Here is the Executive Summary:

I/O Fencing provides protection against data corruption and can guarantee data consistency in a clustered environment. Data is the most valuable component in today’s enterprises. Having data protected and therefore consistent at all times is a number one priority.

This White Paper describes the different deployment methods and strategies available for I/O Fencing. It is designed to illustrate configuration options and provide examples where they are appropriate.

Symantec has led the way in solving the potential data corruption issues that are associated with clusters. We have developed and adopted industry standards (SCSI-3 Persistent Group Reservations [PGR]) that leverage modern disk-array controllers that integrate tightly into the overall cluster communications framework.
