Abstract
Storage shelves of a mass data storage library are organized into a plurality of subsets for the purpose of conducting an inventory of media stored in the shelves. In response to an inventory command, the inventory is conducted in a predetermined order by subset. Upon completion of the inventory of each subset, the completion is posted in a list. A command input detects newly issued commands (subsequent to the inventory command), and places them in a queue. After completion of the inventory of a subset, and upon detecting a command for a non-inventory process (such as a media move), the inventory is interrupted and stopped. The move is conducted, and, upon completion of the move, the inventory is resumed. If a newly issued command is an inventory command, the inventory command is incorporated into the inventory process.
