HP Insight Cluster Management Utility HP Insight CMU remote hardware control API, Diskless check

-n<nodename>

The hostname of the target node to boot.

-i<IP address>

The IP address of the target node to boot.

-m<MAC address>

The MAC address of the target node to boot.

-e<eth device>

The active Ethernet device of the target node to boot.

The boot_node program is typically a subset of the configure_node program, and ensures that the given node is ready to be PXE-booted. It may call /opt/cmu/tools/cmu_add_node_to_dhcp again, and may check that the correct PXE-boot file is in place for the given node.

7.2.6 Diskless check

The diskless_check program is called before the configure_node, unconfigure_node, or boot_node programs are called. This program is called with the following arguments:

-l<CMU diskless logical group name>

The name of the diskless logical group.

The diskless_check program is intended to contain any sanity checks that should be performed before the configure_node, unconfigure_node, or boot_node programs are called. It can also be called directly by the build_image program, to ensure that any prerequisites are met before the diskless image is created. For example, the system-config-netbootimplementation requires that the system-config-netbootrpm provided by HP Insight CMU be installed on the HP Insight CMU management server. A check for the existence of this rpm is performed by the cmu_system-config-netboot_diskless_checkprogram.

After these programs are created, tested, and installed in the /opt/cmu/

diskless/<DISKLESS>/ directory, then you are ready to add this implementation "toolkit" to HP Insight CMU. To do this, add the <DISKLESS> implementation type to the CMU_VALID_DISKLESS_TOOLKITS variable in /opt/cmu/etc/cmuserver.conf.

NOTE: If more than one valid diskless type will be available in HP Insight CMU, this variable must be comma-separated.

7.3 HP Insight CMU remote hardware control API

As of version 5.0, HP Insight CMU supports a remote hardware control API. This hardware API makes it possible to integrate HP Insight CMU power and UID control with any computer that has remote power control capability. The /opt/cmu/bin/cmu_power command interacts with this API to provide remote power and UID control for HP Insight CMU.

As of CMU v7.1 the existing hardware APIs are:

ILO

The most common method of interacting with HP BL/DL/SL servers.

lo100i

The legacy method of interacting with low-end HP servers.

None

The fallback method of interacting with workstations and other servers that do not provide remote power control.

IPMI

The industry standard method, useful with non-HP (or non-iLO HP) hardware.
