Install
both
the
I/O
card

the
cache
cards
back
into
their
original
locations.

re-IPL
the
system.
There
could
be
data

After
an
IPL
to
DST

a
normal
power
off

the
original
system,
the
cache
card

be
cleared.
It
is
then
safe
to
move

storage
procedure
to
clear
data

the
missing

failed
devices
as
follows:
a.
Perform
an
IPL
to
DST.
See
in
the
iSeries
Service
Functions
information.
If
you
cannot
perform
a
type
A

B
IPL,
perform
a
type
D
IPL

One

more
devices
that
are
currently
part
of
the
system
disk
configuration
are
either
missing
or
failed,
and
have
data
in
the
cache
card.
Consider
the
following:
v
The
problem
may
be
because
devices
were
moved
from
the
I/O
card
concurrently,
or
they
were
removed
after
an
abnormal
power
off.
If
this
is
the
case,
locate
the
devices,
power
off
the
system
and
install
the
devices
on
the
correct
I/O
card.
v
If
no
devices
were
moved,
look
for
other
errors
logged
against
the
device,
or
against
the
I/O
card
that
occurred
at
approximately
the
same
time
as
this
error.
