After installing the Hardware Management Agent on Red Hat Enterprise Linux, the hwagentd service starts but you encounter something similar to the following:
Starting Sun HW agent services: . . . . . . . . [ OK ]
hwagentd dead but subsys locked
In addition, there may be a line in the Hardware Management Agent similar to the following:
hwagentd_poller.c:334:hwagent_bmc_response_test):Unable to reach the KCS interface over ipmitool-hwagentd.
This problem is most likely occurring because the IPMI device drivers have not been installed. Hardware Management Agent uses the IPMI drivers to access the KCS interface.
Solution: Install an IPMI system such as OpenIPMI which provides device drivers for full access to IPMI information.
