Figure 8 OSS Files and Disk Volumes
In contrast, Guardian filenames that are not administered through the NonStop Storage Management
Foundation (SMF) are physical names: they mention physical storage devices. A fully qualified
Guardian filename includes the name of a system node, a disk volume name, a subvolume name,
and a name for the file itself. The relationship of Guardian files to disk volumes is illustrated in
Figure 9 (page 82).
The OSS file system allows a high degree of nesting: you can have subdirectories, subsubdirectories,
subsubsubdirectories, and so on. The Guardian environment allows only three levels: volume,
subvolume, and file ID.
In the Guardian environment, you cannot have a volume within a volume. In the OSS environment,
directories that are within directories are common.
