HP OpenVMS Guide to System Security: OpenVMS Version 8.4 > Chapter 12 Securing a Cluster
The cluster environment provides such a rich resource-sharing model (which includes files and volumes, disk and tape devices, and batch and print queues) that it is usually unnecessary to directly access another cluster node through DECnet software. Nonetheless, there are situations where resources may not be uniformly shared across the cluster. This is particularly true in mixed interconnect or local area cluster configurations, where you may choose to limit cluster access to a satellite's disk or tape volumes. In such cases, users need to use the DCL command SET HOST or some form of network access to access a satellite's resources from other cluster members. See “Proxy Access Control” for more information on network access through proxy logins.
