I/O fencing requirements

Depending on whether you plan to configure disk-based fencing or server-based fencing, make sure that you meet the requirements for coordination points:

To configure disk-based fencing or to configure server-based fencing with at least one coordinator disk, make sure a version of Veritas Volume Manager (VxVM) that supports SCSI-3 persistent reservations (SCSI-3 PR) is installed on the VCS cluster.

See the Veritas InfoScale™ Installation Guide.

If you have installed Veritas InfoScale Enterprise in a virtual environment that is not SCSI-3 PR compliant, review the requirements to configure non-SCSI-3 fencing.

See Non-SCSI-3 I/O fencing requirements.
