Abstract
A method for assigning element addresses in an automated data storage library includes determining if a data storage device, such as a tape cartridge, belongs to a particular host's cartridge assignment policy. If so, the data storage device is issued a virtual import/export element address taken from a set of non-common virtual import/export element addresses, if available. If no non-common address is available, then a common virtual import/export element address is assigned to the data storage device. If no addresses, either common or non-common, are available, then the data storage device is queued until an address becomes available.
