HP XC System Software Administration Guide Version 2.1

1.8.2 HP XC File System Layout
Software installed in the /opt/hptc directory is for the exclusive use of the HP XC System
Software. Do not install or replace any other softw a re in this director y, un less it is an officially
supported patch. Software packages are installed in directories under the /opt/hptc directory
under their own names.
________________________ Caution _______________________
Do not add, replace, or remove any files in
the /opt/hptc directory. Doing so
may cause the HP XC system to fail.
Four subdirectories under the /opt/hptc director y contain symbolic links to files included
in the packages:
• /opt/hptc/bin
• /opt/hptc/sbin
• /opt/hptc/lib
• /opt/hptc/man
Each package directory has a subdirec
tory corresponding to each of these directories in which
every file has a symbolic link to the c
orresponding directory. For example, th e SLURM
package has a directory /opt/hptc/
slurm with subdirectories /opt/hptc/slurm/bin,
/opt/hptc/slurm/sbin, /opt/hptc
/slurm/lib,and/opt/hptc/slurm/man.
Every file in /opt/hptc/slurm/bi
n has a symbolic link to /opt/hptc/bin,andthe
files in the other subdirectori
es hav e links into their correspond ing directories.
Figure 1-3 shows the hierarchy under the /opt/hptc directory. Software packages are shown
in boxes with dashed lines. The exam ple directory below the packages co ntains symbolic links
to /opt/hptc/bin, /opt/hptc/sbin, /opt/hptc/lib,and/opt/hptc/man,
