The
Library
Controller
Card
contains
a
copy
of
the
vital
product
data
(VPD)
for
your
library.
The
VPD
contains
your
current
library
configuration.
A
backup
copy
of
this
VPD
is
contained
within
the
electronics
of
the
Library
Enclosure.
When
the
Library
Controller
Card
is
replaced,
the
new
replacement
card
should
contain
zeros
(0’s)
in
key
VPD
locations.
Upon
detection
of
these
zeros,
the
library
will
automatically
attempt
to
write
VPD
data
to
the
new
Library
Controller
Card
from
the
backup
copy
of
the
VPD
contained
in
the
Library
Enclosure.
In
rare
occurrences,
the
new
Library
Controller
Card
may
contain
valid
(non-zero)
VPD
data
left
over
from
having
been
installed
previously
in
another
library.
If
this
occurs,
the
library,
which
is
expecting
to
see
zeros
in
the
VPD
area,
will
instead
detect
valid
VPD
data,
and
will
not
know
which
copy
of
the
VPD
is
the
correct
one.
It
will
detect
a
“VPD
Mismatch”
and
display
on
the
Operator
Control
Panel
