• 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/<nodeName>

• CMU_RCFG_HOSTNAME—The name of the node.
