warm − attempt to warm start current image The command examines memory for a restart block.  If a restart block is found and is correctly formatted, control is transferred to the existing memory image at the entry point given in the restart block.  A restart block contains information which indicates how to re-enter an existing image.  Typically, the existing image has earlier aborted or terminated due to a device failure.  Warm start entry points for the image may attempt to save state that is present in memory, dump core images to secondary storage, or simply reload a new image of the aborted program and restart.  restart(1spp), prom(1spp)
