Space requirements (creating a floor plan)
To be sure that you have enough space for the rack cabinet or suite of rack
cabinets, create a floor plan before you install any rack cabinets. You might have to
prepare and analyze several plans before you choose a final one. If you install
more than one rack cabinet in more than one installation stage, prepare a separate
plan for each installation stage. Consider the following factors when you prepare
each plan:
v Flow of work and personnel within the area
v Operator access to units, as required
v If the placement will be on a raised floor:
– Maximum cable lengths
– Positioning over a cooling register
– Routing and maximum length of cooling lines for the rear door heat
exchanger, if necessary
v If the placement will not be on a raised floor:
– Maximum cable lengths
– Routing and maximum length of cooling lines for the rear door heat
exchanger, if necessary
– Need for cable guards, ramps, or other similar items to protect equipment and
personnel
Location of any planned safety equipment
v
v Future expansion
with an accurate drawing of the installation area (blueprints and floor plans
Begin
are appropriate). Be sure to include the following information in your floor plan:
v Service clearances that are required for each rack cabinet or suite of rack
cabinets
v If the placement will be on a raised floor:
– Things that might obstruct cable or cooling line routes
– The height of the raised floor
If the placement will not be on a raised floor:
v
– The placement of cables and cooling lines to minimize obstruction.
– The amount of cable that is required. (If the cable is routed indirectly between
rack cabinets, such as along walls or suspended from the ceiling, additional
cable might be required.)
– The amount of hose for cooling lines that is required. (If the cooling lines are
routed indirectly between rack cabinets, such as along walls or suspended
from the ceiling, additional hose might be required.)
Locations of equipment, furniture, and building features:
v
– Power receptacles.
– Air conditioning equipment and controls. (Air conditioning outlets should be
located between fronts of facing suites of rack cabinets. Exhausts in the
ceilings should be located between rears of rack suites.)
– File cabinets, desks, and other office equipment.
– Room emergency power-off controls.
– All entrances, exits, windows, columns, and pillars.
10 IBM iDataPlex Cluster Solution: Installation and Service Guide
Page 23
Review the final floor plan to ensure that cable lengths are not too long and that the
rack cabinets have enough clearance.
Power requirements
The rack cabinet does not require electricity, but the servers and optional devices
that you install inside a rack cabinet do require connection to properly wired and
grounded electrical outlets. You might need an electrician to assist you with
planning for electrical requirements. For example:
v Each rack cabinet requires at least one uninterruptible power supply or power
distribution unit (PDU) for servers and optional devices that you install in the rack
cabinet.
v Each PDU or uninterruptible power supply requires a separate ac power branch
circuit.
v The input voltage-selection switch on each device that you install in the rack
cabinet must match the output voltage on the uninterruptible power supply or
PDU.
v Power cords must match electrical outlets at the location where you install the

Chapter 6. Accessing the cluster from a remote location
This chapter includes information about:
v Accessing the cluster from a remote location
v Accessing each server before the operating system is installed
Using the remote power command
The command rpower starts and resets hardware, powers hardware on and off,
and queries the server power state. The syntax is:
rpower <serverrange> [–serverps] [on | off | reset | stat | state | boot | cycle]
[-V|–verbose]
rpower[-h|–help|-v|–version]
PPC (with IVM or HMC) specific:
rpower <serverrange> [–serverps] [of] [-V|–verbose]
Remote console
All iDataPlex solution clusters can support a textual out-of-band console during
BIOS and OS installation and operation. This is achieved either through SOL or
using serial terminal servers. The wcons command accesses the remote console.
This command opens a remote console session for any cluster servers. The syntax
is:
wcons <serverrange>
Displaying server configuration information
The Extreme Cluster Administration Toolkit (xCAT) maintains a database of
configuration information about the servers that are configured in the iDataPlex
solution cluster. To download xCAT, go to http://xcat.sourceforge.net/. To display the
server configuration, type the following command at the console prompt:
lsdef <serverrange>
The output provides information about each server, such as the server type, model
number, serial number, and host name. The output might also provide mapping data
between servers and switches, BladeCenter chassis, and terminal servers.

about IBM products, you will find a wide variety of sources available from IBM to
assist you. This section contains information about where to go for additional
information about IBM and IBM products, what to do if you experience a problem
with your system, and whom to call for service, if it is necessary.
Before you call
Before you call, make sure that you have taken these steps to try to solve the
problem yourself:
v Check all cables to make sure that they are connected.
v Check the power switches to make sure that the system and any optional
devices are turned on.
v Use the troubleshooting information in your system documentation, and use the
diagnostic tools that come with your system. Information about diagnostic tools is
in the Problem Determination and Service Guide on the IBM Documentation CD
that comes with your system.
v Go to the IBM support Web site at http://www.ibm.com/systems/support/ to check
for technical information, hints, tips, and new device drivers or to submit a
request for information.
can solve many problems without outside assistance by following the
You
troubleshooting procedures that IBM provides in the online help or in the
documentation that is provided with your IBM product. The documentation that
comes with IBM systems also describes the diagnostic tests that you can perform.
Most systems, operating systems, and programs come with documentation that
contains troubleshooting procedures and explanations of error messages and error
codes. If you suspect a software problem, see the documentation for the operating
system or program.
Using the documentation
Information about your IBM system and preinstalled software, if any, or optional
device is available in the documentation that comes with the product. That
documentation can include printed documents, online documents, readme files, and
help files. See the troubleshooting information in your system documentation for
instructions for using the diagnostic programs. The troubleshooting information or
the diagnostic programs might tell you that you need additional or updated device
drivers or other software. IBM maintains pages on the World Wide Web where you
can get the latest technical information and download device drivers and updates.
To access these pages, go to http://www.ibm.com/systems/support/ and follow the
instructions. Also, some documents are available through the IBM Publications
Center at http://www.ibm.com/shop/publications/order/.
