Replacing a human operator, an automated message processing system communicates with a data storage subsystem that includes a tape library and a storage controller. The automated message processing system receives messages from a data storage subsystem concerning the availability of tape drives in the tape library. Such messages are selectively routed to one of many specialized expert local facilities (ELFs) for performance of a designated function, such as generation of an appropriate output messages. The ELFs receive input messages and transmit output to the data storage subsystem in order to oversee allocation and use of data storage drives in the data storage subsystem.

[ What is claimed is:] [1.] A method of monitoring allocation of storage drives in a data storage subsystem that includes:a storage controller;a library including multiple storage drives to access removable media, said library including multiple items of said removable media and a library manager coupled to the storage controller; andan automated storage administrator coupled to the library manager and the storage controller, said automated storage administrator including:a plurality of expert local facilities (ELFs), each ELF performing predetermined actions responsive to each message routed thereto;a message director to receive input messages from the storage controller and library manager and route each of the received input messages to at least one ELF;a command generator to receive output messages from the ELFs, place the output messages into a predetermined format and dispatch the formatted output messages to a destination including at least one of the storage controller and the library manager; rein said method comprises:allocating the drives between the storage controller and the library manager;the automated storage administrator receiving a message including a request to re-allocate the drives among the storage controller and the library manager;the message director routing the received message to a first one of the ELFs;the first ELF, in response to the routed message, performing the predetermined actions associated with the ELF, said predetermined actions including generation of an output message summarizing the requested re-allocation of the drives among the storage controller and the library manager;the command generator modifying the output message into a predetermined format to create a formatted output message;selecting a destination in the data storage subsystem from a group including: the library manager and the storage controller; andthe command generator dispatching the formatted output message to the selected destination.
