Disclosed is an automated data storage library for storing and retrieving data storage media in a plurality of storage slots, for a host processor. At least one drive unit is coupled to the host processor for reading and/or writing data on the data storage media. A library manager includes a stored table for identifying the data storage media stored in the storage slots, the stored table indicating artificial scaling of the data storage capacity of selected data storage media to selected values less than the actual data storage capacity thereof. The stored table also stores indicators of attributes of the library with respect to ones of the data storage media, such as indicating that the drive unit is to communicate at the drive/host interface in a specific protocol. The library manager responds to a retrieve signal from the host processor, transporting the selected data storage media to a drive unit, and signaling the drive unit to artificially scale the data storage capacity of the selected data storage media to the selected value therefor identified in the stored table, and/or signaling the drive unit to communicate at the drive/host interface in the protocol of the attributes of the selected data storage media.
An automated data storage library for storing and retrieving data storage media for a host processor, said host processor signaling said automated data storage library to retrieve a selected data storage media, comprising:
In an automated data storage library for storing data storage media in and retrieving data storage media from storage slots, said automated data storage library coupled to at least one host, said host signaling said automated data storage library to retrieve a selected data storage media, said automated data storage library having at least one drive unit coupled to said host at a drive/host interface for reading and/or writing data on said data storage media, at least one robotic accessor for transporting said data storage media-between said storage slots and said at least one drive unit, and a library manager coupled to said at least one host, coupled to said at least one drive unit, coupled to said at least one robotic accessor, and having a stored table, a method for operating said automated data storage library, said host comprising the steps of:
