NMIS provides a number of different methods for managing your nodes, both GUI-based and commandline-oriented. This document describes the commandline tools present in versions 8.5.4 and newer.
Import nodes to NMIS9 from NMIS8
To import nodes from NMIS8 to NMIS9 copy /path/to/nmis8/conf/Nodes.nmis to /tmp/ on NMIS9 installation then:
/usr/local/nmis9/admin/node_admin.pl act=import_bulk nodes="/tmp/Nodes.nmis"
Caveats: you can not import a node to a server if there is already a node existing with that name, you should rename the node before importing.
Bulk Import and Export
For importing lots of nodes in one go from a CSV file, NMIS has been providing
admin/import_nodes.pl for a long time. There is also a sibling
admin/export_nodes.pl tool, and both are documented on the Bulk Import page. The main benefit of these tools is utmost simplicity, but at the cost of some flexibility:
import_nodes does not make all common node properties controllable or accessible.
