OSS File System Concepts
OSS File System Concepts
You use the OSS file system in the same way as you use a UNIX file system. The OSS
file system provides the same functionality as a UNIX file system, but the OSS system
is implemented differently internally. Because the OSS environment must work with the
Guardian environment and the NonStop operating system, the OSS environment has
the following major differences from the standard UNIX operating system:
•
Disk management through the NonStop operating system. The portion of the
NonStop operating system software that performs read, write, and lock operations
on disk volumes is known as the disk process, shown in Figure 1-2 on page 1-6.
