5.4.1 About Logical and Physical Libraries
Before changing the library’s operating mode, make sure you understand the distinction
between the physical library and logical libraries, as follows:
•
The physical library consists of the entire XLS system, including the Library
Resource Module (LRM), any attached Media Expansion Modules (MEMs), all
tape drives, all cartridges slots, all I/O ports, the medium changer interface, the
robotics, and all HBAs in the system controll
er’s expansion slots.
•
A logical library is one of up to eight partitions of XLS physical resources. Logical
libraries are defined to ensure that different software applications have restricted
and dedicated access to specific tape drives, cartridge slots, and I/O ports. All
logical libraries share access to the
XLS’s medium changer interface on a first-
come, first-served basis.
