When the osg roll is installed during the initial installation of your server (or cluster), the procedure is documented in section 1.2 of Rocks® usersguide. You should reach a screen as shown below.

Select the osg roll from the list of available rolls when you see a screen like shown below:

During the installation process, there will be two screens related to the osg roll. As shown below.

The first to choose the default hadoop primary and secondary servers.

The second to choose the default gridservers CE (gatekeeper), SE (bestman), GUMS servers.

If not sure leave it as is, these default can be changed later any time.

Once the osg roll is loaded the installer will continue installation automatically with no further user input.

Other appliances can be made part of the execution pool through setting an appliance attribute and reinstalling those nodes.
