The default download method for a computer is defined in the MDB on the manager. The computer properties dialog can be used to set the download method for individual computers. In addition, the in-context pop-up menu for computers and computer groups allow for setting the download method for multiple computers in one go.
The download method stored in the MDB is used during software deployment. Each software job will honor the download method the target computer is configured to use at the time the job container is sealed and evaluated. Changing the download method of a computer after a job container has been sealed and evaluated will not be honored by the software jobs. Obviously, consecutive job containers will honor the new download method.
The default download method for a computer can also be configured from the agent. The agent command line interface (sd_acmd SetDownloadMethod) provides the means to set the download method in the MDB. After a successful job check and scalability server/domain manager information exchange the new value will appear in the MDB.
Note: The manager will only allow the download method to be set to DTS, if both the Software Delivery and Data Transport Service agent components are registered for that agent in the MDB.
In addition to the command line method, the advanced tab in the DSM software delivery properties dialog of the CAF system tray provides a graphical way of modifying the default download method for a computer. By modifying the row named “Software Delivery: Request a specific Network Operating System”, the default download method MDB update sequence is triggered.
Do not confuse the row named “Software Delivery: Request a specific Network Operating System” with the row “Software Delivery: Network Operating System”. The latter modifies only the local configuration store of the agent with the purpose of forcing the agent to use NOS-less download methods, even if the scalability server provides network shares. Setting it to, for example, MS, does not guarantee the use of shares and it may get overridden by the default download method or the scalability servers capabilities and configuration. The default download method of DTS cannot be overridden by the agent.
