Be aware of the following information about the HP XC file system layout:
•Open source software that by default would be installed under the /usr/local directory is instead installed in the /opt/hptc directory.
•Software installed in the /opt/hptc directory is not intended to be updated by users.
•Software packages are installed in directories under the /opt/hptc directory under their own names. The exception to this is
•Four directories under the /opt/hptc directory contain symbolic links to files included in the packages:
•/opt/hptc/bin
•/opt/hptc/sbin
•/opt/hptc/lib
•/opt/hptc/man
Each package directory should have a directory corresponding to each of these directories in which every file has a symbolic link created in the /opt/hptc/ directory.
