Can anyone tell me if this is correct? Yes, this is correct. The caveat here is to make sure you are not overloading your HVD SCSI channels with IO, or HAFO might make 'false positive' path 'switch' decisions because of IO timeouts. If you get the most recent version of HAFO patches for 7.0 or 7.5, you can disable timeouts as a trigger for failover events ( in case you are getting false positive failovers ). It is not recommended to disable timeouts, until you are sure you would otherwise see lots of 'false alarms'.
