HP XC System Software Administration Guide Version 3.1

1.2.1.3 HP XC Service Configuration Files
The /opt/hptc/etc/ directory includes several subdirectories containing scripts used to configure
services on nodes at installation time.
The /opt/hptc/etc/sconfig.d directory contains scripts for system configuration.
The /opt/hptc/etc/gconfig.d directory contains scripts used to gather information needed to
configure a service on the HP XC system.
The /opt/hptc/etc/nconfig.d directory contains scripts associated with specific services, which
configure nodes that run these services .
The /opt/hptc/etc/cconfig.d directory contains scripts associated with client-specific services.
1.2.2 Log Files
The software components that comprise the HP XC system generate their own log files. As discussed in
Chapter 7: Monitoring the System (page 83), some information is aggregated from local nodes to regional
nodes and from regional nodes to the global node.
Table 1-1 lists the components and the pathname of their log files.
