4.7 HP Insight CMU image editor

An existing HP Insight CMU cloning image can be modified directly on the HP Insight CMU management node, without making the modifications on a golden node and backing up the system. Image editing involves three steps:

1.Use the cmu_image_open command to expand the image.

2.Make changes.

3.Use the cmu_image_commit command to save the image.

4.7.1 Expanding an image

An HP Insight CMU cloning image is stored in /opt/cmu/image. The image is composed of several archives, one per partition. The cmu_image_open command analyzes the image directory content and expands all the archives into the image directory. Depending on the cloning image size, this script can take several minutes to complete. For example:

#/opt/cmu/bin/cmu_image_open -i rh5u4_x86_64

image <rh5uh_x86_64> untared into </opt/cmu/image/rh5u4_x86_64/image_mountpoint>

After editing the image, commit changes:

#cmu_image_commit -i rh5u4_x86_64

After this command is complete, the subdirectory image_mountpoint in the image directory contains the expanded image:

#ls /opt/cmu/image/rh5u4_x86_64/image_mountpoint/
