CMU_RCFG_PATH —The path to the root directory of the
image. /opt/cmu/image/<imageName>/root
•
CMU_RCFG_OSTYPE —The type of operating system detected by HP Insight CMU.

5.8.2.10.3 Using reconf-diskless-snapshot.sh
The reconf-diskless-snapshot.sh script is invoked at the end of each node registration,
when the snapshot directory of a compute node has been created. All node-specific changes
are made in this script. For example, if you have a network card that needs a static IP address,
add the commands to create the ifcfg- file in this file.
IMPORTANT: If you need a customization file in the snapshot directory, you must also put the
name in the file /opt/cmu/image/my_diskless_image/snapshot/files.custom.
The content of the reconf-diskless-snapshot.sh script provided by HP Insight CMU is:
#!/bin/bash
#cmu_begin_interface
#do not change anything in this section
#add custom code after this section
CMU_RECONF_DISKLESS_SNAPSHOT_VERSION=1
# starting with cmu version 4.2
# this script is now dedicated to custom code
# this code is executed as the last step of the creation
# of snapshot directories
#
# this script is invoked by /opt/cmu/tools/cmu_dl_post_snapshot
#
# environment variables available:
#
# CMU_RCFG_PATH = path where the root filesystem is located
# CMU_RCFG_HOSTNAME = hostname of the compute node
# CMU_RCFG_IP = mgt network ip of this compute node
# CMU_RCFG_IMAGENAME = name of this image in cmu
#cmu_end_interface
#-- custom code starts here --
exit 0
The script is invoked with the following four input parameters:
•
CMU_RCFG_PATH —The path to the snapshot directory of the
node. /opt/cmu/image/<imageName>/snapshot/
•
CMU_RCFG_HOSTNAME —The name of the node.
