Figure 18 New autoinstall logical group

After the autoinstall logical group is created, the HP Insight CMU image directory contains a new

directory with the name of the logical group. This directory contains:

• autoinst.tmpl.orig—An exact copy of the autoinstall file.

• repository—A logical link to the autoinstall repository.

For example:

# ls -l /opt/cmu/image/rh5u5_autoinstall/

total 4

-rw-r--r-- 1 root root 1313 Oct 11 13:48 autoinst.tmpl-orig

lrwxrwxrwx 1 root root 31 Oct 11 13:48 repository ->

/data/repositories/rh5u5_x86_64

4.2.4.3 Registering compute nodes

To enable autoinstall, a compute node must be registered in the autoinstall logical group. Registration

is the same as registering a normal HP Insight CMU logical group.

4.2.4.4 Autoinstall compute nodes

When you start autoinstall on a compute node, the following files are created:

• autoinst.tmpl-cmu—A copy of your autoinstall file with additional directives required by

HP Insight CMU.

• autoinst-[compute_node_hostname]—The autoinstall template with hard-coded

node-specific information.

• pxelinux_template—The pxelinux boot parameter file template for this logical group.

• pxelinux-[ compute_node_hostname]—The pxelinux boot parameter file for a specific

node.

For example:

# ls -l /opt/cmu/image/rh5u5_autoinstall/

total 24

-rw-r--r-- 1 root root 2881 Oct 11 15:38 autoinst-node1

-rw-r--r-- 1 root root 2861 Oct 11 15:38 autoinst.tmpl-cmu

-rw-r--r-- 1 root root 1313 Oct 11 15:35 autoinst.tmpl-orig

-rw-r--r-- 1 root root 13 Oct 11 15:38 node1.log

-rw-r--r-- 1 root root 832 Oct 11 15:38 pxelinux-node1

-rw-r--r-- 1 root root 830 Oct 11 15:38 pxelinux_template

lrwxrwxrwx 1 root root 31 Oct 11 15:35 repository -> /data/repositories/rh5u5_x86_64
