3.5 Set up views
The views concept allows you to set up the iXOS-JUKEMAN file system to
your liking. This way a structure can be built to present all the disks
clearly to network users.
For instance, if you had hardware managing 700 disks and all these disks
would be visible as subdirectories to a single root directory, the clients
accessing the data might be presented with problems to find the desired
disks. For this reason like in every file system a tree structure should be
established, the disks being the leaves of this tree.
This allows not only the client access to be controlled but also the access
to special disks will be made easier for the clients. A software developer
may want to use only certain disks contraining PC products. It would
speed up his or her work, if he or she could see just the disks he or she
needs.
Moreover, different clients need different views to the file system. PCs
usually need the file name format 8.3 with no consideration for upper or
lower case, whereas some UNIX NFS clients prefer to use long file names
embedded in the optional Rock Ridge extensions to the ISO 9660 file
system standard. Or some clients may access all the disks, whereas other
clients may only use a certain subset of the available disks.
iXOS-JUKEMAN supports a variety of views to the file system, which differ
in the name format and the number of visible disks. Figure 1on page 70
presents some examples for different views in different name formats.

hs
High Sierra format
The PC format is a modified High Sierra format, optimized for PC clients.
The version number is suppressed and all file names will be converted to
lower case. This is most important for PC clients that do the conversion to
upper case characters themselves. If these clients received names in up-
per case the file names would be converted into strange, generic names.
By default the file names will be in 8.3 format due to compatability resons
for Windows for Workgroup clients. This behavior can be configured with
the server parameter fullvn (see Server parameterson page 123). In
