DFS simplifies the administration of operating system-specific or host-specific files by providing the @sys and @host variables. When the Cache Manager encounters @sys or @host in a pathname, it replaces the variable with either the system name (defined with the cm sysname command) or the hostname (defined with the local operating system's hostname command or its equivalent).
The @sys and @host variables are especially useful when constructing symbolic links from the local disk to the DFS filespace. You create identical links on all machines, yet each machine accesses the files that are appropriate to its system type or hostname. Use the @sys variable to access files that are organized on a per-system type basis; use @host to access files that are organized on a per-machine basis. The following topics provide examples of the @sys and @host variables.
