ClusterPack Tutorial

the basic state of a computer system. An image does not generally include all files however. By default,
/
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 r
e
to the image reflect the different reasons for creating it. Administrators may create a "recovery" image o
f
node in the event that the node experiences hardware failure or the file system is accidentally removed o
r
corrupted. Administrators may also create a "golden" image for the purpose of installing it on other node
s
insure that each node in their cluster is configured exactly the way they want.
Overview
z
Clean up anything on the system that shouldn't be in the image.
z
Ensure that the system isn't being used.
z
Run sysimage_create to create the Golden Image.
Details
z
Log into the Compute Node to be archived.
z
Perform general file system cleanup/maintenance. For example, it may be desirable to
search for and remove core files.
N
ext, from the Management Server:
z
Ensure that the system is not being used. It is advisable that the system stop accepting new
LSF jobs while the archive is being made:
% badmin hclose <hostname>
z
In addition, you should either wait until all running jobs complete, or suspend them:
% bstop -a -u all -m <hostname>
z
Execute sysimage_create on the Management Server and pass the name of the file from
which you would like the image to be made. For example:
% /opt/clusterpack/bin/sysimage_create <hostname>
z
Monitor the output for possible error conditions. The image will be stored
in /var/opt/ignite/archives/<hostname>
After the image creation is complete, the Compute Node should be opened for accepting Clusterware job
% badmin hopen <hostname>
