1.5.2 Distribute Golden Image to a set of Compute Nodes To distribute a golden image to a set of Compute Nodes, you need to first register the image. To register the image, use the command: % /opt/clusterpack/bin/sysimage_register If the image was created with sysimage_create, the full path of the image was displayed by sysimage_create. Images are stored in the directory: /var/opt/ignite/archives/ To distribute the golden image to the Compute Nodes, use the command: % /opt/clusterpack/bin/sysimage_distribute [ hostname | all ] The keyword "all" can be used distribute the image to all of the Compute Nodes in the cluster, or a single hostname can be specified. sysimage_distribute will reboot each Compute Node for installation with the specified image. If the image was sent to a node that was already part of the cluster, that node must have the Compute Node software reconfigured. For more information see the "Software Upgrades and Reinstalls" section. % compute_config -a If the image was sent to a node that will be added to the cluster, please see the "Add Node(s) to the Cluster" use case.

The clsysfile tool was created to allow the system administrator to bundle inidividual files for installation and depolyment on the compute nodes. This allows certain files to be customized or altered on the compute nodes after a Golden Image is created.

1.5.2 Distribute Golden Image to a set of Compute Nodes
To distribute a golden image to a set of Compute Nodes, you need to first register the image. To
register the image, use the command:
%
/opt/clusterpack/bin/sysimage_register <full path of image>
If the image was created with sysimage_create, the full path of the image was displayed by
sysimage_create. Images are stored in the directory:
/var/opt/ignite/archives/<hostname>
To distribute the golden image to the Compute Nodes, use the command:
%
/opt/clusterpack/bin/sysimage_distribute <full path of image>
[ hostname | all ]
The keyword "all" can be used distribute the image to all of the Compute Nodes in the cluster,
or a single hostname can be specified. sysimage_distribute will reboot each Compute Node for
installation with the specified image.
If the image was sent to a node that was already part of the cluster, that node must have the
Compute Node software reconfigured. For more information see the "Software Upgrades and
Reinstalls" section.
%
compute_config -a <node name>
If the image was sent to a node that will be added to the cluster, please see the "Add Node(s) to
the Cluster" use case.

1.5.3 Managing system files on the compute nodes
Managing individual files on the compute nodes following an image push can require a lot of
time. The clsysfile tool was created to allow the system administrator to bundle inidividual files
for installation and depolyment on the compute nodes. This allows certain files to be
customized or altered on the compute nodes after a Golden Image is created.
