HP Insight Cluster Management Utility manual Configure diskless node, Unconfigure diskless node

-l<CMU diskless logical group name>

The name of the logical group to delete.

The delete_image program is expected to delete everything related to the diskless OS in /opt/ cmu/image/<CMU diskless logical group name>/.

7.2.3 Configure diskless node

The configure_node program is called when a compute node is added to the HP Insight CMU diskless logical group of type <DISKLESS>. This program is called with the following arguments:

-l<CMU diskless logical group name>

The name of the diskless logical group.

-s<NFS server IP>

The IP address of the NFS server.

-n<nodename>

The hostname of the target node to configure.

-i<IP address>

The IP address of the target node to configure.

-m<MAC address>

The MAC address of the target node to configure.

-e<eth device>

The active Ethernet device of the target node to configure.

The configure_node program is expected to perform any node-specific tasks related to the diskless image. This may include calling /opt/cmu/tools/cmu_add_node_to_dhcp to configure the node to PXE-boot, and to produce a PXE-boot file for the compute node.

7.2.4 Unconfigure diskless node

The unconfigure_node program is called when a compute node is removed from the HP Insight CMU diskless logical group of type <DISKLESS>. This program is called with the following arguments:

-l<CMU diskless logical group name>

The name of the diskless logical group.

-n<nodename>

The hostname of the target node to unconfigure.

-i<IP address>

The IP address of the target node to unconfigure.

The unconfigure_node program is expected to unconfigure and/or remove anything related to the given node. This may include calling /opt/cmu/tools/cmu_remove_node_from_dhcp to prevent the node from PXE-booting, and to delete any PXE-boot file related to the given compute node.

7.2.5 Boot diskless node

The boot_node program is called when a compute node is booted from HP Insight CMU into the HP Insight CMU diskless logical group of type <DISKLESS> (as opposed to a reboot command from the OS). This program is called with the following arguments:

-l<CMU diskless logical group name>

The name of the diskless logical group.

-s<NFS server IP>

The IP address of the NFS server.
