18 Contact PLC and get the attributes for this node. Also, parse in
19 options from the node model strong.
21 Also, update any node network settings at PLC, minus the ip address,
22 so, upload the mac (if node_id was in conf file), gateway, network,
23 broadcast, netmask, dns1/2, and the hostname/domainname.
25 Expect the following keys to be set:
26 SKIP_HARDWARE_REQUIREMENT_CHECK Whether or not we should skip hardware
29 The following keys are set/updated:
30 WAS_NODE_ID_IN_CONF Set to 1 if the node id was in the conf file
31 WAS_NODE_KEY_IN_CONF Set to 1 if the node key was in the conf file
32 BOOT_STATE The current node boot state
33 NODE_MODEL The user specified model of this node
34 NODE_MODEL_OPTIONS The options extracted from the user specified
36 SKIP_HARDWARE_REQUIREMENT_CHECK Whether or not we should skip hardware
38 NODE_SESSION The session value returned from BootGetNodeDetails
39 INTERFACES The network interfaces associated with this node
40 INTERFACE_SETTINGS A dictionary of the values of the interface settings
42 Return 1 if able to contact PLC and get node info.
43 Raise a BootManagerException if anything fails.
