Library Partitioning and Element Addressing

Library 4U systems with firmware versions of 1.70 and higher, and containing at
least 2 drives, have the ability to configure two logical libraries (create two
partitions). This partitioning has been expanded with the new library firmware and
half-high drive integration. Now it is possible to configure 1, 2, 3 or 4 partitions in
the 4U library. Additionally the 2U library can now be configured into one or two
partitions. Each library must contain at least one drive per logical library
(partition).
Partitioning of 2U Libraries
When two half high drives are installed in a 2U library, the library firmware will
support partitioning in the same way that the 4U supports partitioning with two
full high drives today. The first partition will contain the first magazine and the
first drive. The second partition will contain the second magazine and the second
drive. The I/O station (if configured as I/O) will be shared, as is done with the
partitioned 4U library.
One full high drive is "Drive 1". When using half high drives, the first half high
drive position will be called "Drive 1", The second half high drive position will be
called "Drive 2."
Partitioning of 4U Libraries
When one or more half high drives are added to a 4U library, the drive naming
will change. Currently, the first full high drive is "Drive 1" and the second full high
drive is "Drive 2". When you consider that each full high drive slot may contain
one or two half high drives, there are four potential drives in the space that used
to occupy two. As a result, the first half high drive position, or the first full-high
drive position, will be called "Drive 1". The second half high drive position will be
