4.2.5.3Autoinstall compute nodesTo autoinstall a node, enter the following command at the cmucli prompt:cmu> autoinstall "image" node1

For example:

cmu> autoinstall "rh5u5_autoinst" node1

or

/opt/cmu/bin/cmu_autoinstall_node -1 rh5u5_autoinst -f nodes.txtWhere nodes.txt is the list of nodes to autoinstall.4.2.6 Customization

The /opt/cmu/etc/cmuserver.conf file includes an autoinstall section with several groups of variables. A brief description follows. For a full description of the autoinstall configuration variables, see cmuserver.conf.

autoinstall

This is a “read only” section that lists the variables HP Insight CMU can substitute, if

template filespresent, in autoinstall templates.
variables

For example, a Red Hat kickstart file normally has a keyword “nfs –server” followed

 

 

by the IP address of the server exporting the Red Hat repository. When running HP

 

Insight CMU autoinstall for Red Hat kickstart, replace the IP address with CMU_MGT_IP.

 

HP Insight CMU makes the substitution.

 

For another example, you normally specify the default gateway to configure on the

 

node in the autoinstall template files. With HP Insight CMU autoinstall, you can replace

 

the real IP address of the default gateway with the variable CMU_MGT_GW. HP Insight

 

CMU replaces the variable. If you do not want HP Insight CMU to make the replacement,

 

do not use the variable in your template. Instead, use the real value.
customized title

The variable CMU_CLUSTER_NAME can be changed to an arbitrary string (or left unset)

barsto provide GUI and CLI title customization.
pxelinux

Variables in this section contain the HP Insight CMU default parameter list for pxelinux.

parametersChange the pxelinux parameters by editing variables in this section.

 

For example, if your compute nodes use ttyS1 as the console port for a Red Hat

 

autoinstall, change the value of CMU_KS_KERNEL_PARMS by replacing “console=ttyS0”

 

with “console=ttyS1”. For all subsequent creations of Red Hat autoinstall logical groups,

 

ttyS1 is used as the default value for the console port instead of ttyS0. To change

 

pxelinux parameters for a single compute node, edit the

 

pxelinux-[compute_node_hostname]file in the autoinstall logical group directory.

 

The changes are permanent because this file is not overwritten by subsequent

 

autoinstalls. To change pxelinux parameters for a single autoinstall logical group, edit

 

the pxelinux_template file in the autoinstall logical group directory.
timeout

Allow modification of timeout values for different phases of the autoinstall process. For

parameters

example, if disk formatting takes a long time due to large disk size, you may need to

 

increase CMU_AUTOINST_INSTALL_TIMEOUT.
