Abstract
An automated data storage library accesses data storage media from storage shelves in response to commands from external host(s). The library receives a code update image while continuing to operate. The library is operated to an off-line status at external interface(s) that permit communication with the host(s). Then, and after the image is stored in nonvolatile memory, the processor(s) are reset, thereby activating the code update image, the processor(s) subsequently coming up from the reset to an operational state. Then, the library goes to an on-line status at the external interface(s).
