HP Insight Cluster Management Utility - Manual (Page 116)

-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.
