On a Linux system, if you opt to manually install the Oracle Hardware Management Agent component using a tool such as rpm (not using the Oracle Hardware Management Pack installer), you will need to start the agent service after installation. Once started, the agent will perform as intended. When installing Oracle Hardware Management Pack using the installer, you are prompted to start any required services.
Use one of the following commands to manually start the Hardware Management Agent:
For systems running Oracle Linux or Red Hat Linux versions 4, 5 and 6, and SUSE Linux versions 10 and 11:
# service hwmgmtd start
For systems running Oracle Linux or Red Hat Linux version 7, and SUSE Linux version 12:
# systemctl start hwmgmtd
