1.8.1 General File System Layout
The HP XC system relies on key files. I nt erf ering with these files may cause the system
to fail. The best way to avoid this situation is to respect the placement of directories and
files, especially when installing software packages. You can avoid many pitfalls by strictly
maintaining separation between the HP XC System Software and other software. The key files
and directories are:
/bin
Holds the binary executable files that any user can invoke.
/sbin
Holds the binary executable files that are specifically for the system
administrator or designated privileged users.
/etc
Contains files for th e configuration of the system and components of
the sy ste m, includ in g networ king information, printers, and so o n.
/opt
Holds software packages from HP and other vendors.
_______________ Note _______________
Make individual directories for each vendor or software
product. There are tw o separate subdirectories, one for
HP XC system software and one for other HP software
products, under th is directory.
/opt/hp
This directory is reserved for optio nal H P ap pli cations and utilit ies
that are not related to the HP XC system. HP ServiceGuard for
Linux is an example of such a package.
/usr
Maintains a hierarchy of stan dar d co mmands and f iles.
/usr/bin
Holds the binary executable files that any user can invoke.
/usr/sbin
Holds the binary executable files that are specifically for the system
administrator or designated privileged users.
/usr/local
Provides an area to store executable programs that were produced
locally.
/var
Holds various log, spooling, and temporary storage directories.
/tmp
Provides temporary file storage.
New non-HP packages m ay break the system. Be sure to assign individual areas when using
Relocatable software packages, that is, do not intermingle other vendors’ software with the HP
XC system files directories.
