Using Koan To Re-Install Running Systems - Red Hat NETWORK SATELLITE 5.3.0 Reference Manual

Using Koan to Re-install Running Systems

koan --server=hostname --list-profiles
This command lists all of the available profiles created with cobbler profile add.
Then, begin the process of creating the image file and starting the installation of the virtual guest
system.
koan --virt --server=cobbler-server.example.com --profile=virtualfileserver
--virtname=marketingfileserver
The command specifies that a virtual guest system be created from the Cobbler server (hostname
cobbler-server.example.com) using the virtualfileserver profile. The virtname option specifies
a label for the virtual guest, which by default is labeled with the system's MAC address.
Once installation of the virtual guest is complete, it can be used as any other virtual guest system.
11.6.2. Using Koan to Re-install Running Systems
There may be instances where you need to re-install a machine with another operating system while it
is still running. koan can help you by destructively replacing a running system with a new installation
from the available Cobbler profiles.
To replace a running system and install a new one, run the following command on the system itself:
koan --replace-self --server=hostname --profile=name
This command, when executed on the running system to be replaced, will start the provisioning
process and replace its own system using the profile in --profile=name on the Cobbler server
specified in --server=hostname.
