Extended Flexibility for Fencing Protocol

This new functionality allows the customization of the default fencing protocol. Choices include SCSI-3, SCSI-2, or per-device discovery.

This flexibility enables the default usage of SCSI-3, a more recent protocol, for better support for multipathing, easier integration with non-Sun storage, and shorter recovery times on newer storage while still supporting the Sun Cluster 3.0 or 3.1 behavior and SCSI-2 for older devices. See Administering the SCSI Protocol Settings for Storage Devices in Sun Cluster System Administration Guide for Solaris OS for more information.
