Hot-Pluggable
PCI
Adapter
Removal
Attention:
The
Linux
operating
system
does
not
support
these
hot-plug
procedures.
Also,
Linux
does
not
support
hot-plugging
any
hot-pluggable
PCI
adapters.
Systems
with
Linux
installed
on
one
or
more
partitions
must
be
shut
down
and
powered
off
before
replacing
any
PCI
adapter
assigned
to
a
Linux
partition.
Follow
the
non-hot-pluggable
adapter
procedures
when
replacing
a
PCI
adapter
in
any
partition
with
Linux
installed.
Note:
Removing
a
hot-pluggable
PCI
adapter
requires
the
system
administrator
to
take
the
PCI
adapter
offline
before
performing
any
PCI
adapter
hot-plug
procedures.
Before
taking
an
adapter
offline,
the
devices
attached
to
the
adapter
must
also
be
taken
offline.
This
action
prevents
a
service
representative
or
user
from
causing
an
unexpected
outage
for
system
users.
For
additional
information
about
taking
an
adapter
offline
or
removing
it
from
the
system
configuration,
see
the
AIX
System
Management
Guide:
Operating

The
AIX
Documentation
CD
contains
the
base
set

for
the
operating
system,
including

and
end-user
documentation.
This
publication
is
also
contained
