11.1 About Physical and Logical Libraries
11-2
501801 Rev. 07-01-19
•
Logical Libraries 1 and 2 have each been assigned an I/O port, respectively;
Logical Library 3 does not have an assigned I/O port.
•
The software applications and the host computers connect to and communicate
with the tape drives independently of the medium changer.
Important:
The 10 slots in a single I/O port cannot be shared among
logical libraries. If a logical library needs access to an
I/O port, it must be assigned the entire port when the
library is defined.
