1Introduction
The functionality, mechanics and design of the PRIMERGY SX30 storage
subsystem are optimally adapted to the PRIMERGY servers. It can be used as
rack or floorstand model. In the 19-inch rack, the SX30 subsystem occupies
three height units.
The PRIMERGY SX30 storage subsystem can accommodate up to fourteen
1-inch hard disk drives. If it is equipped, e. g. with 146 Gbyte Ultra 160/320 SCSI
drives, approximately 2 Tbyte hard disk memory is available as a maximum
within one housing.
The PRIMERGY SX30 exists in a single-node, as well as in a dual-node version.
Whereas the one-channel option (1 x 14 HDD) and the two-channel option (2 x
7 HDD) are both available for the single-node version, there is only the twochannel option for the dual-node (cluster) version.
The cluster capability is made possible by the use of dual node SCSI modules.
In conjunction with the Microsoft Windows 2000 Advanced Server, two
PRIMERGY servers can be run over two channels on a two-channel
PRIMERGY SX30 storage subsystem via one RAID controller each. As a result
of the dual node SCSI module, both servers are connected to each SCSI
channel in the storage subsystem.
Server Management/ServerView
ServerView uses the SAF-TE protocol of the SCSI bus to communicate with the
clients.
ServerView and the related agents are set up within the group of servers and
storage subsystems being monitored. The received informations are evaluated
by ServerView and processed for display or forwarding to the administrator
(manager).
I When installing PRIMERGY SX30 Storage Subsystems in connection
with ServerView please install the ServerStart CD version 3.29 or higher
on each of the connected servers.
Notes to installing and update see at the documentation of ServerView (see
also “Related publications” on page 93).

5 Power Supply
5.1 Power Supply Units
The PRIMERGY SX30 storage subsystem contains one power supply unit that
guarantees the power supply to all the fitted components. The second slot
(2 power supply units as a standard with the dual-node version) is equipped with
a dummy unit.
I To guarantee a redundant power supply, a second power supply unit
must be added. If one power supply unit fails, the system will carry on
running.
Figure 11: PRIMERGY SX30 Storage Subsystem with two Power Supply Units (Rack Model)
The power supply units are supplied with mains voltage via the supplied
connecting leads.
Power supply units (1) and (2) can be connected directly to two different phases
of the in-house circuit in order to achieve phase redundancy (see section “Mains
Connection with Phase Redundancy” on page 64).

5.1.1 Replacing the Power Supply Unit
V CAUTION!
It is imperative that you read the chapter chapter “Important Notes” on
page 13 in this manual before you carry out work on your storage
subsystem.
If faults occur with the power supply unit, it could be necessary to replace a
power supply unit. Information about the relevant error messages can be found
in the sections “Meaning of the Operating Status LEDs” on page 22 and “Power
Supply Unit LEDs” on page 28 and in the chapter chapter “Fault Clearing” on
page 85.
Figure 12: Power Supply Unit Removed
V CAUTION!
When a power supply unit is replaced in a non-redundant power supply
system (only one power supply unit present) the server must be
switched off or the SCSI channels deactivated.
Ê If only one power supply unit is present, shut down the server and switch it
off.
Ê Remove the lead of the defective power supply unit.
Ê Raise the lower catch on the power supply unit and carefully remove it from
its slot by pulling on the upper catch. To remove the power supply unit the

6Fan Module
The redundant fan module ensures cooling of the PRIMERGY SX30 storage
subsystem. It is equipped with two fans. If one fails, the other working fan sufficiently guarantees cooling and prevents the components of the storage
subsystem from overheating.
A temperature sensor on the rear panel of the power supply unit and a revolution
monitor fitted for each fan are used to permanently check the cooling. Error
messages can be read on the cooling status LED on the front panel of the
storage subsystem (see section “Meaning of the Operating Status LEDs” on
page 22) and on the fan LED (see section “Fan LED” on page 26).
As soon as fan failure is detected, the fan module with the defective fan should
immediately be replaced with an intact module so that the redundancy characteristics (availability) are retained.
I Only the complete fan module may be replaced.
I The fan module can be replaced during operation.
V CAUTION!
The fan module should be replaced within 30 seconds to prevent
possible overheating.

7 SCSI Drives
The PRIMERGY SX30 storage subsystem can accomodate up to fourteen
1-inch hard disk drives. If it is equipped, e. g. with 146 Gbyte Ultra 160/320 SCSI
drives, approximately 2 Tbyte hard disk memory is available as a maximum
within one housing.
With the one-channel option, all of the fourteen U320 SCSI hard disk drives are
assigned only to this channel, and are accessible via a single node SCSI
module.
With the two-channel option, seven U160/320 SCSI hard disk drives at a time
are assigned to each of the two independend SCSI channels, and are accessible via two single-node SCSI modules in each case, as well as via the dual
node SCSI module.
The SCSI hard disk drives are built into a frame which allows defective drives to
be replaced (hot replacement) or new drives to be added (hot adding) during
operation.
The “Hot Replace“ function can only be performed together with a corresponding RAID configuration. Further information about the RAID configuration
or RAID level can be found in the disk array controller documentation.
A drive may only be replaced if it is inactive (see description of the LEDs in the
table “Meaning of the Status LEDs Indications” on page 25) or has been marked
as defective in the management tool.
The hot replacement procedure increases the availability of the system
operation and guarantees a high degree of data integrity and protection against
failure.

Handling Hard Disk Drives SCSI Drives
7.1 Handling Hard Disk Drives
Hard disk drives are highly sensitive electromagnetic devices and must be
handled with great care. It is extremely likely that an incorrect handling will lead
to a partially and/or total failure of the hard disk drives.
These failures will result in data errors and to loss of data or to total destruction
of the hard disk drive.
Please observe following rules, which will help to avoid the occurrence of this
type of problems:
● Store and transport hard disk units only within the limits stipulated in the
specification.
● When transporting hard disk units (even over short distances), always use
the original packaging (ESD labeling).
● Never expose a hard disk unit to a temperature shock. Avoid the formation
of condensation inside and on the outside of the hard disk drives.
The hard disk drives may be exposed only to defined temperature and
climatic conditions.
● Always put the hard disk unit down carefully, with its largest surface facing
downwards, to avoid the danger of tipping over.
7.2 Fitting/Removing Drive/Blank Insert
V CAUTION!
Under no circumstances should you remove a hard disk unit while the
system is in operation if you are not sure that the hard disk drive is
operated by a RAID controller and belongs to a disk array which is
operating in RAID level 1, 5, 10 or 50.
The drives must all be marked clearly so that they can be put back into
the original slots after an upgrade. If this is not taken into account,
existing data can be destroyed.
The hard disk drives which can be ordered for the PRIMERGY SX30 storage
subsystem are delivered pre-installed in the slide-in hard disk units. Only a
service technician may remove a hard disk drive from the hard disk unit.
44 U41169-J-Z156-4-74
Page 45
SCSI Drives Fitting/Removing Drive/Blank Insert
Free slots are provided with a blank insert which must be removed before fitting
another hard disk unit.
The blank insert is fitted and removed in the same way as the hard disk drives.
Removing the blank insert
Installation/removal of the blank insert occurs for a part of storage subsystems
identically to the installation/removal of the hard disk units. For the other
subsystems follow the steps bellow:
Ê Press the upper and lower tabs on the blank insert together (see figure 18
on page 45) until the locking mechanism disengages, and remove the blank
insert from the slot.
Installation of the blank insert occurs in reverse order.
Figure 18: Blank Inserts and corresponding Hard Disk Units
V CAUTION!
Keep the blank insert for future use. If you remove the hard disk unit
again and do not fit a replacement, you must put back the blank insert
because of cooling, adherence to EMC (electromagnetic compatibility)
requirements and fire protection.

SCSI Drives Fitting/Removing Drive/Blank Insert
Removing occurs in reverse order.
The hard disk units are provided with a transport lock (position 1 on figure 20).
This transport lock causes a blocking of the locking/unlocking mechanism of the
hard disk unit. The transport lock has to be removed before disengaging the
locking mechanism.
Figure 20: Hard Disk Unit: removing the transport lock
I Keep the safety lock pins.
For further server transportation you must lock the hard disk units with
the transport lock again (push the safety lock pin carefully and slantwise
through the opening below the locking mechanism, until it gets stuck).
Ê Pull the hard disk unit out. Note the instructions in the section “Handling
Hard Disk Drives” on page 44.

Hot-Swap for SCSI Hard Disk Drive SCSI Drives
7.3 Hot-Swap for SCSI Hard Disk Drive
V CAUTION!
Only pull out the hard disk units if the green HDD busy LED is not on.
If you want to replace an SCSI hard disk drive during operation, proceed as
follows:
Ê If you want to pull out a hard disk drive which is not defective, it must be set
to “Offline“ beforehand via the software (e.g. Mylex + GAM).
Ê Pull the hard disk drive (defective/not defective) out by a few centimeters.
Ê Wait for at least 60 seconds.
I This period is necessary for the RAID controller to recognize that a
hard disk drive has been pulled out and for the hard disk drive to come
to a stop.
Ê Pull the hard disk unit right out.
Ê Insert the new hard disk unit.
When you have removed the hard disk unit and are not fitting any replacement,
then fit a blank insert into the blank slot. Ensure that the blank insert engages
in the slot correctly.

Figure 26: Dual Node SCSI Module
The dual node SCSI module allows two server to access the SCSI drives of one
of the two available SCSI channels in the storage subsystem. This ensures
server redundancy or common data access (Low Cost Clustering). If the host
has a RAID controller with 2 channels, 2 times 7 hard disk drives are available
twice via the two dual node SCSI modules (see chapter “Configurations” on
page 65).
The dual node SCSI module provides an Automatic Isolator Function if the
jumper X4 on figure 26 is setting. This function (default setting) allows the
replacement of the corresponding module without switching OFF the storage
subsystem (see table 11).

11.5 Requirements of the Rack
The rack systems of the Fujitsu Siemens Computers GmbH (19-Inch (Classic)
Rack, DataCenter Rack and PRIMECENTER Rack) fully support the installation
of the PRIMERGY server systems. The installation in rack systems of several
other manufacturers (3rd-Party Rack) available at present is supported to a
large part.
To accommodate the ventilation concept and ensure proper ventilation of the
components in the rack, any unused areas must be closed using dummy covers.
Power is supplied via the socket strips available in the rack.
The mounting of the cable management is described in detail in the Technical
Manual for the respective rack.
U41169-J-Z156-4-74 71
Page 72
Requirements of the Rack Installation
The main features of the rack systems of the Fujitsu Siemens Computers GmbH
are:
PRIMECENTER Rack
– Frontally bolted telescopic rails or sliding rails.
The rails are provided with a linear alignment facility to ensure also an
adjustment to different rack depths (except in the rear left area, where a
support bracket is used).
– Extended cable management within the lateral rack area.
DataCenter Rack
– Frontally or laterally (using a grid) bolted telescopic rails or sliding rails
(except within the rear left area, where a support bracket is used).
– Extended cable management within the lateral rack area.
19-Inch (Classic) Rack
– Laterally (using a grid) bolted telescopic rails or sliding rails.
– Cable management using a hinged cable carrier.
The mounting of the telescopic rails and the assembly brackets in the different
racks is described in the next sections.
72 U41169-J-Z156-4-74
Page 73
Installation Requirements of the Rac
k
When installing rack systems of several other manufacturers, the following
applies:
3rd-Party Rack
Some general conditions must observed:
– Installation dimensions (see the dimensions shown in figure 40 on page 74).
1 rack front side
2 rack rear side
A rack depth (comparison PRIMECENTER Rack 940/1000 mm)
B rack width (comparison PRIMECENTER Rack 700 mm)
C clearance of the 19-inch installation level
C1 front 19-inch installation level
C2 rear 19-inch installation level
D area for cable routing (cable area depth) and ventilation
E area for front panel and ventilation
F right and left area for support systems
P PRIMERGY installation depth
a1 front left support upright
a2 front right support upright
b1 rear left support upright
b2 rear right support upright
– The operability of the server safety mechanisms, e.g. stoppers or holding
back systems, must be guaranteed.
– The form of the rack support uprights must ensure the frontal screwing on of
the telescope rails.
– Frontally bolted telescopic rails or gliding rails.
The rails are provided with a linear alignment facility to ensure also an
adjustment to different rack depths.
– No support for the cable management delivered with the mounting kit.
– Climatic conditions.
An air intake unimpeded to a large extent in the rack front and an air
discharge in the rear cover of the rack are necessary for the ventilation of the
installed server.
In principle, the ventilation concept envisages that the necessary cooling is
reached by the horizontal self-ventilation of the installed devices (air flow
from the front to the rear).
– Power supply.
Presence of appropriate socket strips must be ensured for the installation in
3rd-Party Racks.

Problem Solutions and Tips Fault Clearing
12.1 Problem Solutions and Tips
The following sections describe irregularities which can be observed on the
storage subsystem in case of faults. Their possible causes are named and there
are instructions for fault clearing.
12.1.1 Power Supply Indication (Front)
If the power supply indication is green the device is switched on and the power
supply and power supply units are OK.
12.1.1.1 Power supply indication remains dark
Power cable not connected correctly
Ê Ensure that the power cable on the storage subsystem and the safety socket
are connected correctly.
Power supply units defective
Ê Check the LEDs of the power supply units.
If the operating indication (green LED) is dark on the power supply units and
the error indication (amber LED) is on, the power supply units are defective.
Ê Replace the power supply units.
12.1.1.2 Power supply indication is yellow
One of the installed power supply units has failed
Ê Check which one of the power supply units has failed. On the rear panel of
the storage subsystem there is an amber LED and a green LED on all the
power supply units. If only the amber LED is ON, the power supply unit is
defective or the power supply don’t receive power.
86 U41169-J-Z156-4-74
Page 87
Fault Clearing Problem Solutions and Tips
Ê Replace the defective power supply unit (see section “Replacing the Power
Supply Unit” on page 36).
The problem is cleared if
– the green LED on the power supply unit is ON and
– the power supply indication on the front panel of the storage subsystem
is green.
12.1.1.3 Power supply indication is flashing orange
The device is switched OFF and in the standby mode.
Ê Switch the device ON (see section “Switching the Storage Subsystem
ON/OFF” on page 83).
Ê If the LED remains orange, the power supply units may have failed. Replace
the power supply units. If the LED then still remains orange, contact our
service organization.
12.1.2 Cooling Status
If the cooling status LED is green, both the installed fans and the interior temperature of the storage subsystem are OK.
12.1.2.1 Cooling status LED is yellow
I This indication means that a redundant fan is defective, but the temper-
ature is OK.
One of the fans is defective
I In this case, the status LED on the fan module is yellow (see section “Fan
LED” on page 26).
Ê Replace the fan module (see section “Fitting/Removing the Fan Module” on
page 40).
U41169-J-Z156-4-74 87
Page 88
Problem Solutions and Tips Fault Clearing
V CAUTION!
It is imperative when replacing the fan module during operation that
you take no longer than 30 seconds, since otherwise the temperature
in the storage subsystem can exceed the permissible limit values.
After the fan module has been replaced successfully, both the status LED on the
fan module and the cooling status LED must be green again.
12.1.2.2 Cooling status LED is orange
In this case there is a cooling fault.
Ê Check whether or not all the fans have failed. In this case the status LED on
the fan module is orange (see chapter “Fan Module” on page 39).
If the status LED on the fan module is green or yellow, the temperature in the
device is too high although the fans (or at least one of the fans) are working.
Check whether or not the ambient temperature is too high or the air outlet on
the rear panel of the device is obstructed.
All the fans have failed
Ê Immediately shut down the system to prevent overheating damage in the
device.
Ê Replace the fan module (see section “Fitting/Removing the Fan Module” on
page 40).
V CAUTION!
It is imperative when replacing the fan module during operation that
you take no longer than 30 seconds, since otherwise the temperature
in the storage subsystem exceeds the permissible limit values.

12.1.4 Storage Subsystem Switches OFF
Temperature too high
The temperature sensors have measured an increased temperature and the
server has shut down the system.
Ê Wait until the storage subsystem has cooled down.
12.1.5 System does not Start Up after New Drives have
been Installed
SCSI configuration incorrect (disk array controller)
Ê Call up the configuration menu and check the drive settings (device config-
uration) and the additional settings (advanced configuration options).
12.1.6 Hard Disk Drive Operating Indication does not
Come ON
Ê Check whether the hard disk drive has been correctly installed and locked
(see section “Fitting/Removing Drive/Blank Insert” on page 44).
