Library
4U
systems
with
firmware
versions
of
.80
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).
In
a
partitioned
library,
the
Operator
Control
Panel
(OCP)
only
reports
the
status
of
logical
library
1
in
the
main
menu
due
to
space
limitations.
The
user
must
navigate
to
the
logical
libraries
status
in
the
OCP
to
get
the
information
on
the
additional
library
partitions.
Partitioning
of
2U
Libraries
When
two
half
height
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
height
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
height
drive
is
″Drive
1
″.
When
using
half
height
drives,
the
first
half
height
drive
position
will
be
called
″Drive
1
″,
The
second
half
height
drive
position
will
be
called
″Drive
2.
″
Partitioning
of
4U
Libraries
When
one
or
more
half
height
drives
are
added
to
a
4U
library,
the
drive
naming
will
change.
Currently,
the
first
full
height
drive
is
″Drive
1
″
and
the
second
full
height
drive
is
″Drive
2
″.
When
you
consider
that
each
full
height
drive
slot
may
contain
one
or
two
half
height
drives,
there
are
four
potential
drives
in
the
space
that
used
to
occupy
two.
As
a
result,
the
first
half
height
drive
position,
or
the
first
full-high
drive
position,
will
be
called
″Drive
1
″.
The
second
half
height
drive
position
will
be
called
″Drive
2
″.
The
third
half
height
drive
position,
or
the
second
full
height
drive
position,
will
be
called
″Drive
3
″.
The
fourth
half
height
drive
position
will
be
called
″Drive
4
″.
Mixing
of
Drives
The
library
will
support
a
mix
of
full
height
and
half
height
drives
in
the
same
physical
library
and
the
same
logical
library.
They
will
support
a
mix
of
Gen
3
and
Gen
4
drives
in
the
same
physical
library
and
the
same
logical
library.
They
will
also
support
a
mix
of
SCSI,
SAS,
and
Fibre
Channel
in
the
same
physical
library
and
the
same
logical
library;
however,
mixing
drive
interface
types
in
the
same
logical
library
is
not
recommended.
Configuration
of
a
1
Partition
System
A
one
partition
system
configured
for
a
4U
library
contains
any
and
all
drives
present
in
any
drive
positions,
and
it
will
contain
all
four
magazines.
