Installation Directory Structure

The directories that contain the Foundation Services are created on the master-eligible nodes. Most of the Foundation Services software is installed in the /opt/SUNWcgha and /etc/opt/SUNWcgha directories. However, device drivers in the Foundation Services software are installed in standard Solaris directories, for example, the /kernel/drv directory.

The following table summarizes the installation directory structure.

Table A-1 Installation Directory Structure

Directory

Description

/etc

The /etc/opt/SUNWcgha directory is used for configuration files.

The /etc/opt/SUNWcgha/init.d directory is used for startup scripts.
