1.5.1 Create a Golden Image of a Compute Node from the Management
Server
A system image is an archive of a computer's file system. Capturing the file system of a
computer captures the basic state of a computer system. An image does not generally include
all files however. By default, /tmp and other temporary files, network directories and host
specific configuration files are not included.
A system image may be referred to as a golden image or a recovery image. The different names
used to refer to the image reflect the different reasons for creating it. Administrators may create
a "recovery" image of a node in the event that the node experiences hardware failure or the file
system is accidentally removed or corrupted. Administrators may also create a "golden" image
for the purpose of installing it on other nodes to insure that each node in their cluster is
configured exactly the way they want.
The HP Technical Cluster includes a tool to simplify the process of creating images:
%
/opt/clusterpack/bin/sysimage_create
The recommended procedure for creating a golden image of a Compute Node is:
Log into the Compute Node to be archived.
Perform general file system cleanup/maintenance. For example, it may be
desirable to search for and remove core files.
