One cartridge magazine cannot be assigned to two logical libraries. If you partition a multi-drive library,
each of the magazines must be assigned to a logical library on a magazine boundary. The entire magazine
must be part of one logical library only.
Note: If you have a 2U library with two drives, you can have two logical libraries.
In a fully populated 4U library with four half height drives and four logical libraries, resource
assignments are:
v Logical Library 1 contains Drive 1 and the lower left cartridge magazine.
v Logical Library 2 contains Drive 2 and the upper left cartridge magazine.
v Logical Library 3 contains Drive 3 and the lower right cartridge magazine.
v Logical Library 4 contains Drive 4 and the upper right cartridge magazine.
Note: For information about various configurations, see "Library partitioning and element addressing"
on page 29.
The I/O station and slots that are reserved for cleaning cartridges, if any, are shared among all logical
libraries.
