The Question is: From what I read about FibreChannel SANs, you can only access a given disk from one system (directly, as opposed to MSCP). On CI-based clusters, the disks all appear local to all machines. Can this type of multi-host direct access be done to FibreChanne l SAN disks? I see stuff added in v7.3-1 related to this in that PPT slideshow, but I do not think I see exactly this; merely failover and/or MSCP-related stuff. Or is this now possible? Thanx. The Answer is : A large number of systems can a have simulateous direct connections to disks on a Fibre Channel Disk system. The exact limit is dependent on the particular disk system. A Fibre Channel Disk System can be configured with multiple ports, and OpenVMS systems support multiple Fibre Channel adapters to provide redundant paths for load balancing or to guard against many types of hardware failures. And MSCP can certainly also be used to access a Fibre Channel disk from an OpenVMS system that has a direct connection to it.
