One of the methods used is called logical names. Think of them as
glorified environment variables that the file system understands.


you you do DIR SYS$MANAGER:

the system automatically translates "SYS$MANAGER" (there are multiple
iterations) until it gets to:


systemdevice:[SYS0.SYSMGR]  and systemdevice:[VMS$COMMON.SYSMGR]

You can create logical names with multiple values, so the file system
looks for files in multiple directories.

Clustering makes extensive use of this. The first translation points to
a directory structure that is specific to a node (such as SYS0) and then
a directory structure which is common to all nodes in the cluster
(vms$common).
