ABSTRACT:
When an automated data storage library includes the capability of storing and accessing more than one media type, it is necessary for the library manager to keep track of what media type is associated with each volume serial number ("VOLSER"), and where each is physically located in the library. For efficiency, VOLSERs will be grouped in sequential ranges, each range associated with a single media type (although a particular media type can be associated with different, non-contiguous ranges). When the number of VOLSERs and ranges is small, new ranges can be easily added, and existing ranges can be easily deleted or modified, manually by a system administrator. However, when the number of VOLSERs and ranges becomes large, it becomes burdensome for the administrator to track the VOLSER ranges and media types. An automated VOLSER range management system is provided which detects whether a new or modified range overlaps or is adjacent to an existing range with the same media type. If so, the system automatically combines the ranges.
