Abstract
A method and apparatus for booting a client data processing system from a set of boot images stored on a server data processing system. At power up of the client data processing system, an image request is sent to the server data processing system from the client data processing system. According to a state of the client data processing system, an initial boot image is selected and sent to the client data processing system. The state of the client data processing system is monitored. Responsive to an indication that the client data processing system needs to be rebooted, a new boot image is selected, if needed depending on the state, and sent to the client data processing system. This selection is made according to the state of the client data processing system at the time the indication is identified. The client data processing system is rebooted using the boot image from the server data processing system.
