ILOCM

The method for integration with HP Moonshot 1500 Chassis.

The HP Insight CMU hardware API consists of a collection of programs that reside in /opt/cmu/ hardware/<HW_TYPE>/ where <HW_TYPE> refers to the name of the hardware API. For example the iLO API programs reside in the /opt/cmu/hardware/ILO/ directory.

The name of the API programs in the hardware API directory must conform to the following format:

cmu_<HW_TYPE>_power_<ACTION>

Where <ACTION> is one of:

off

Remove power from the server.

on

Apply power to the server.

osoff

Attempt a graceful shutdown of the OS before removing power.

uid_off

Turn off the UID light.

uid_on

Turn on the UID light.

These are the five basic actions required by HP Insight CMU.

NOTE: A boot command from HP Insight CMU is comprised of the osoff action followed by the on action.

The following additional actions are supported by the /opt/cmu/bin/cmu_power command, but are not required by HP Insight CMU:

status

Provide a power status for the given node, either on or off.

press

Simulate a "momentary press" of the power button.

To recap: the following programs are required when implementing a new FOO hardware API:

/opt/cmu/hardware/FOO/cmu_FOO_power_off /opt/cmu/hardware/FOO/cmu_FOO_power_on /opt/cmu/hardware/FOO/cmu_FOO_power_osoff /opt/cmu/hardware/FOO/cmu_FOO_power_uid_off /opt/cmu/hardware/FOO/cmu_FOO_power_uid_on

All of these programs are invoked with the following arguments:

<PROGRAM> -n <NODENAME> -i <BMC_IP> -e <ERRFILE>

Where:

<NODENAME>

The hostname of the target server.

<BMC_IP>

The IP address of the management card for the target server.

<ERRFILE>

The name of the file to log any errors.

After a new HP Insight CMU hardware API is developed and tested, it must be added to HP Insight CMU as a valid hardware type. To do this, add the name of the new hardware API to the CMU_VALID_HARDWARE_TYPES variable in /opt/cmu/etc/cmuserver.conf. As of CMU

v7.1 this is the setting of this variable:
