Provisioning HowTo

8.1.2.4. Cobbler System Record

Cobbler system records are objects within cobbler that keep track of a system and its associated

kickstart profile. To do PXE kickstarting you'll need to ensure that a Satellite kickstart profile is tied to

Cobbler system records corresponding to the machines you intend to PXE kickstart to that profile. To

make this association:

1. Visit the System details page of each system in question and click on the Provisioning link

2. Select the kickstart profile you want to associate it with

3. Click the Create Cobbler System Record button.

Once you've made this association, it will remain in place forever unless you have set

pxe_just_once to true in cobbler for any given machine. In that case the association will be broken

after a successful kickstart.

Without this association, a machine that PXE bootstraps to a Satellite server will be presented with a

menu of kickstart profiles which requires manual interaction.

8.1.2.5. Cobbler Boot ISO

The Cobbler boot iso is a disk image that can be built on your Satellite server and burned to a cd or

dvd. You can then boot any system with it. When you do you will see a menu of available kickstarts

similar to the one you would see if you PXE boot a machine off a Cobbler server without a system

record. Simply select the kickstart you want, and the system will start to install itself. Any time you add

a kickstart within Satellite, you will need to recreate the ISO and re-burn it to an optical disc.

To create a boot iso, log in to your Spacewalk server as root and run cobbler buildiso. The ISO

will contain all kernel/initrd images stored in your Satellite along with all associated kernel argument

settings. Kickstart files will be sourced remotely. This means that changes to the kickstart templates

can be made without having to re-burn the CD. If you create a new kickstart profile and want to use it

via the cobbler boot iso, you will need to recreate a fresh disc.

Note

Due to issues with the version of syslinux shipped with Red Hat Enterprise Linux 4, this

command will not work unless the Satellite is running on Red Hat Enterprise Linux 5. Also

since syslinux is not available for s390x, it is not possible to use this on a satellite running

on s390x.

8.2. Re-Provisioning

Re-provisioning is the act of reinstalling an existing system. It could be reinstalled to the same version

and release, or to a completely new version. When you re-provision through the Satellite web interface

your system will use the same system profile that it had before it was re-provisioned. This can be

useful as much of the information and settings about the system such as its history will be preserved.

You can schedule a re-provision from the provisioning tab while viewing a system. If you would like

to configure additional options click on the Advanced Options page. On this page you can configure

details such as kernel options, networking information, and package profile synchronizations. The

Kernel Options section pertains to kernel options used during kickstart. Post Kernel Options are the

kernel options that will be used after the kickstart is complete and the system is booting for the first

time.
