to overwrite another user's data. Methods to secure the library against shared usage are
discussed in
Linux shared object files (page 22) .
2. For similar reasons, the tape library or partition should not be shared between different host
PCs or servers. To share the library with multiple computers, use the library's partitioning and
security features to ensure the LTFS tapes are only accessible to a single host computer.
3. The expected usage is to mount the tape library, and read or write data to the tape cartridges
after it has identified the files on each piece of media in the library. Allow sufficient time for
this identification process to complete. Media with barcodes may be imported and exported
from the library for use with other LTFS solutions.
4. HP StoreOpen Automation will work in conjunction with Graphical User Interface (GUI)
programs, such as Nautilus and Konqueror on Linux. However, be aware that these applications
will pre-read files in the tape filesystem. Therefore, GUI software may result in poor
performance. For optimum performance use a terminal console and issue command line (shell)
commands to copy data, view directory contents, and so forth.
Architecture
HP StoreOpen Automation is a software application compatible with popular enterprise Linux and
Mac OS operating systems. It makes use of the Open Source FUSE kernel mode subsystem available
for all supported Linux systems. On the Apple Mac OS platform it uses the MacFUSE module.
HP StoreOpen Automation also has dependencies on other Open Source applications, which the
user must install prior to using the HP StoreOpen Automation software. These are discussed in
Configure the open source software dependencies (page 9)

NOTE: Responses to the filesystem commands flow in the reverse direction, from the library device
to the user.
