10. An open systems based removable media storage library system for use by one or more hosts, the removable media storage library system comprising:
a first hosted partition including a plurality of first physical storage slots, a plurality of first logical storage slots, and a plurality of first hosted storage media that is positioned within the plurality of first physical storage slots, the plurality of first logical storage slots being inaccessible by any of the hosts; and
a pool partition including a plurality of pool resources, wherein one of the plurality of pool resources is selectively assigned to the first hosted partition.
11. The library system of claim 10 wherein the plurality of pool resources includes a plurality of pool storage slots and a plurality of pool storage media, and wherein the one of the plurality of pool resources is selectively assigned from the pool partition to one of the first logical slots in the first hosted partition.
12. The library system of claim 10 wherein one of the plurality of first hosted storage media is selectively assigned from the first hosted partition to the pool partition.
13. The library system of claim 10 further comprising a second hosted partition including a plurality of second physical storage slots, a plurality of second logical storage slots, and a plurality of second hosted storage media that is positioned within the plurality of second physical storage slots, wherein one of the plurality of pool resources is selectively assigned to the second hosted partition.
14. The library system of claim 13 wherein one of the plurality of second hosted storage media is selectively assigned from the second hosted partition to the pool partition.
15. The library system of claim 10 wherein the pool partition inaccessible by any of the hosts.
16. The library system of claim 10 wherein the open systems based removable media storage library system includes a SCSI based removable media storage library system.
17. A method for sharing storage media within an open systems based removable media storage library system that is used by one or more hosts, the method comprising the steps of:
providing a plurality of first hosted resources within a first hosted partition that can be accessed by one of the hosts;
providing a plurality of pool resources within a pool partition that is inaccessible by any of the hosts; and
selectively assigning one of the plurality of pool resources to the first hosted partition.
18. The method of claim 17 wherein the step of providing the plurality of first hosted resources includes the first hosted resources including a plurality of first physical storage slots, a plurality of first logical storage slots, and a plurality of first hosted storage media that is positioned within the plurality of first physical storage slots.
19. The method of claim 18 wherein the step of selectively assigning includes the step of selectively assigning one of the plurality of pool resources to one of the first logical slots in the first hosted partition.
20. The method of claim 19 further comprising the step of selectively assigning one of the plurality of first hosted resources from the first hosted partition to the pool partition.
21. The method of claim 17 further comprising the steps of providing a plurality of second hosted resources within a second hosted partition that can be accessed by one of the hosts, and selectively assigning one of the plurality of pool resources to the second hosted partition.
