9.9 DECnet Cluster Alias
9.9 DECnet Cluster Alias
You should define a cluster alias name for the OpenVMS Cluster to ensure that
remote access will be successful when at least one OpenVMS Cluster member is
available to process the client program’s requests.
The cluster alias acts as a single network node identifier for an OpenVMS Cluster
system. Computers in the cluster can use the alias for communications with
other computers in a DECnet network. Note that it is possible for nodes running
DECnet for OpenVMS to have a unique and separate cluster alias from nodes
running DECnet–Plus. In addition, clusters running DECnet–Plus can have one
cluster alias for VAX, one for Alpha, and another for both.
Note: A single cluster alias can include nodes running either DECnet for
OpenVMS or DECnet–Plus, but not both. Also, an OpenVMS Cluster running
both DECnet for OpenVMS and DECnet–Plus requires multiple system disks
(one for each).
Reference: See Chapter 4 for more information about setting up and using a
cluster alias in an OpenVMS Cluster system.
