OS Provisioning

With the Provisioning module, you can automatically provision the required operating system on a server without even having to connect to the server. In most circumstances, you are not required to type a command at the target system's prompt (for example,OBP) or turn on and off power switches. This automated hands-free installation is invaluable for you to install several hundred machines. You can push an operating system onto a host from a centralized location rather than initiating the request from the host.

At a high level, provisioning OSs using the Provisioning module involves the following steps:

1. Creating (load or import) an OS image
2. Creating an OS profile based on an OS image
3. Provisioning an OS on systems based on the OS profile and its associated OS image

The first two steps are one-time tasks for each OS configuration that you want to provision. Check the System Requirements page for the list of OSs that you can provision with Sun xVM Ops Center.

Image File Default Location

When importing image files, a default location is predefined. The default location is:
/var/opt/SUNWscn/images
/var/opt/SUNWscn/proxyImageCache

This default location is defined by the satellite and proxy properties files:
satellite.properties
proxy.properties

The satellite and proxy properties files are located in the following directory:
/etc/opt/sun/n1gc

To Change the Default Location for FW and OS Image Files

To change the default location for the Operating System and Firmware image files, do the following:

1. Edit the satellite and proxy properties files in the /etc/opt/sun/n1gc directory.
   /etc/opt/sun/n1gc/satellite.properties
   /etc/opt/sun/n1gc/proxy.properties
2. Change the default directory in the satellite and proxy configuration files:
   id.satellite_base_dir= /var/opt/SUNWscn/images
   id.proxy_base_dir= /var/opt/SUNWscn/proxyImageCache
   Note: The id.satellite_base_dir value must be changed in both the satellite and proxy properties files.
3. Depending on whether you are pointing to a new satellite or to proxy directories, manually move/copy the entire directory structure (one or both) to the new directory. This includes any previously imported image files.
4. Restart the satellite and proxy instances.

Note: If the default directory for importing image files is changed, both FW and OS image files are affected.
