Abstract

A controller of an automated data storage library is configured to store information regarding operation of the library in a memory; to reserve at least one data storage cartridge; and to operate a data storage drive and the memory to transfer at least a portion of the information stored in the memory to the reserved data storage cartridge. The library controller is configured to maintain an externally available inventory of data storage cartridges of the library, e.g. for a host system, and excludes the reserved data storage cartridge from the inventory.

Claims

1. An automated data storage library comprising:

a plurality of storage shelves configured to store data storage cartridges;

at least one robot accessor configured to transport said data storage cartridges;

at least one data storage drive configured to read and write data with respect to data storage cartridges;

at least one memory; and

at least one library controller configured to operate said at least one robot accessor to transport said data storage cartridges;

configured to store information regarding operation of said automated data storage library in said at least one memory; and

configured to reserve at least one data storage cartridge, and to operate said at least one data storage drive and said at least one memory to transfer at least a portion of said information stored in said at least one memory to said reserved at least one data storage cartridge; and

wherein said library controller additionally is configured to maintain an externally available inventory of data storage cartridges of said library, and excludes said reserved at least one data storage cartridge from said externally available inventory.

3. The automated data storage library of claim 1, wherein said library controller additionally is configured to indicate externally that said operated data storage drive is not being used.

4. The automated data storage library of claim 1, wherein said library controller is configured to, at predetermined intervals, operate said at least one data storage drive and said at least one memory to transfer at least a portion of said information stored in said at least one memory to said reserved at least one data storage cartridge.

5. The automated data storage library of claim 1, wherein said library controller is configured to respond to at least one predetermined event, to operate said at least one data storage drive and said at least one memory to transfer at least a portion of said information stored in said at least one memory to said reserved at least one data storage cartridge.

6. The automated data storage library of claim 1, wherein said library controller additionally is configured to, at start up, operate said at least one data storage drive and said at least one memory to transfer at least a portion of information stored in said reserved at least one data storage cartridge to said at least one memory to initialize said memory for storing information regarding operation of said automated data storage library.

7. The automated data storage library of claim 1, wherein said memory comprises a non-volatile memory, such that said memory may retain said information regarding operation of said automated data storage library, for a subsequent start up of said library.

2. (canceled)

8. A data storage system comprising:

at least one host system; and

an automated data storage library comprising;

a plurality of storage shelves configured to store data storage cartridges;

at least one robot accessor configured to transport said data storage cartridges;

at least one data storage drive configured to read and write data with respect to data storage cartridges;

at least one interface configured to allow communication between said automated data storage library and said at least one host system;

at least one memory; and

at least one library controller configured to operate said at least one robot accessor to transport said data storage cartridges;

configured to store information regarding operation of said automated data storage library in said at least one memory;

configured to reserve at least one data storage cartridge, and to operate said at least one data storage drive and said at least one memory to transfer at least a portion of said information stored in said at least one memory to said reserved at least one data storage cartridge; and

configured to maintain an inventory of data storage cartridges of said library, said inventory available to said at least one host system via said interface, and to exclude said reserved at least one data storage cartridge from said inventory.

9. The data storage system of claim 8, wherein said library controller additionally is configured to indicate to said at least one host system that said operated data storage drive is not being used.
