2. Has anyone used such a scenario where the storage (forgive me if I offend some vendors out there) does not support a SCSI-3 Persistence Reservation requirement? (SCSI-3 PR is a requirement for the CFS for split brain,etc) SCSI-III RESERVATION a Veritas only fencing mechanism. I think anyone not using storage testing in Veritas iLAB (therefore not SCSI-3 PR compat) is very foolish. This requirement does limit the list of supported SAN arrays There are other CFSes out there that work with all SAN arrays. -- //www.freelists.org/webpage/oracle-l
