Installing a drive The following notes describe the types of hard disk drives and tape drives that the server supports and other information that you must consider when installing a drive: v The server supports up to six 1-inch (26 mm) slim-high, 3.5-inch, hot-swap hard disk drives without an optional SAS backplane installed. The server supports 12 hard disk drives when an optional SAS backplane is installed. v For a list of supported options for the server, see http://www.ibm.com/servers/ eserver/serverproven/compat/us/. v The hot-swap bays are arranged horizontally in the standard hard disk drive cage; the server scans the hard disk drives and assigns drive IDs in the following order: 0 through 11. v Inspect the drive tray for signs of damage. v Make sure that the drive is correctly installed in the tray. v If a RAID controller is installed in the server, see the documentation that comes with the controller for instructions for installing a hard disk drive. v All hot-swap drives in the server should have the same throughput speed rating; mixing drives with different speed ratings might cause all drives to operate at the lower throughput speed. v To minimize the possibility of damage to the hard disk drives when you are installing the server in a rack configuration, install the server in the rack before installing the hard disk drives. v You do not have to turn off the server to install hot-swap drives in the hot-swap drive bays. However, you must turn off the server when performing any steps that involve installing or removing cables. v If the server will be configured for RAID operation using a ServeRAID controller, you must configure the disk arrays before installing the operating system. See the ServeRAID documentation on the IBM ServeRAID Support CD for additional information about RAID operation and complete instructions for using ServeRAID Manager. v The server supports up to two 5.25-inch, half-high, SCSI tape drives or one full-high SCSI tape drive in the 5.25-inch bays. A SCSI adapter is required to support the tape drives. Install the adapter in the first available slot that is nearest the I/O board to ensure that you can connect the SCSI cable to the tape drive. Route the SCSI cable along the same path as the existing media-signal cable. Start at the SCSI adapter and route the SCSI cable over the I/O board and through the cable retention clip; then, route the cable through the cable channel and through the server to the 5.25-inch tape drive bays. To install a full-high tape drive, remove the metal rails and screws from inside the chassis and attach the rails to the tape drive using the four identical screws. Fasten the drive in the bay using the two remaining screws. To install a half-high tape drive, remove the blue rails from the back of the 5.25-inch filler panel and snap the rails on the tape drive. The following illustration shows the cable routing and the location of the rails and screws for installing a full-high tape drive. 32 IBM System x3800 Type 8865: User's Guide

Installing
a
drive
The
following
notes
describe
the
types
of
hard
disk
drives
and
tape
drives
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
drive:
v
The
server
supports
up
to
six
1-inch
(26
mm)
slim-high,
3.5-inch,
hot-swap
hard
disk
drives
without
an
optional
SAS
backplane
installed.
The
server
supports
12
hard
disk
drives
when
an
optional
SAS
backplane
is
installed.
v
For
a
list
of
supported
options
for
the
server,
see
eserver/serverproven/compat/us/.
v
The
hot-swap
bays
are
arranged
horizontally
in
the
standard
hard
disk
drive
cage;
the
server
scans
the
hard
disk
drives
and
assigns
drive
IDs
in
the
following
order:
0
through
11.
v
Inspect
the
drive
tray
for
signs
of
damage.
v
Make
sure
that
the
drive
is
correctly
installed
in
the
tray.
v
If
a
RAID
controller
is
installed
in
the
server,
see
the
documentation
that
comes
with
the
controller
for
instructions
for
installing
a
hard
disk
drive.
v
All
hot-swap
drives
in
the
server
should
have
the
same
throughput
speed
rating;
mixing
drives
with
different
speed
ratings
might
cause
all
drives
to
operate
at
the
lower
throughput
speed.
v
To
minimize
the
possibility
of
damage
to
the
hard
disk
drives
when
you
are
installing
the
server
in
a
rack
configuration,
install
the
server
in
the
rack
before
installing
the
hard
disk
drives.
v
You
do
not
have
to
turn
off
the
server
to
install
hot-swap
drives
in
the
hot-swap
drive
bays.
However,
you
must
turn
off
the
server
when
performing
any
steps
that
involve
installing
or
removing
cables.
v
If
the
server
will
be
configured
for
RAID
operation
using
a
ServeRAID
controller,
you
must
configure
the
disk
arrays
before
installing
the
operating
system.
See
the
ServeRAID
documentation
on
the
IBM
ServeRAID
Support
CD
for
additional
information
about
RAID
operation
and
complete
instructions
for
using
ServeRAID
Manager.
v
The
server
supports
up
to
two
5.25-inch,
half-high,
SCSI
tape
drives
or
one
full-high
SCSI
tape
drive
in
the
5.25-inch
bays.
A
SCSI
adapter
is
required
to
support
the
tape
drives.
Install
the
adapter
in
the
first
available
slot
that
is
nearest
the
I/O
board
to
ensure
that
you
can
connect
the
SCSI
cable
to
the
tape
drive.
Route
the
SCSI
cable
along
the
same
path
as
the
existing
media-signal
cable.
Start
at
the
SCSI
adapter
and
route
the
SCSI
cable
over
the
I/O
board
and
through
the
cable
retention
clip;
then,
route
the
cable
through
the
cable
channel
and
through
the
server
to
the
5.25-inch
tape
drive
bays.
To
install
a
full-high
tape
drive,
remove
the
metal
rails
and
screws
from
inside
the
chassis
and
attach
the
rails
to
the
tape
drive
using
the
four
identical
screws.
Fasten
the
drive
in
the
bay
using
the
two
remaining
screws.
To
install
a
half-high
tape
drive,
remove
the
blue
rails
from
the
back
of
the
5.25-inch
filler
panel
and
snap
the
rails
on
the
tape
drive.
The
following
illustration
shows
the
cable
routing
and
the
location
of
the
rails
and
screws
for
installing
a
full-high
tape
drive.
