Fujitsu Siemens Computers SX series User manual

U41272-J-Z385-3-76 1
1Preface
With the business servers in the SX series (abbreviated to: SX servers), Fujitsu Siemens
Computers is pursuing its strategy of opening up the BS2000/OSD operating system by
making available a modern hardware solution which is based on SPARC64™technology
and represents a future-safe investment for the customer.
The OSD Extended Configuration (OSD/XC) software package includes a ported variant of
the BS2000/OSD basic configuration which offers high performance when run on the
SX servers' SPARC64 architecture. Further software packages included in the OSD/XC
package extend the functionality available in the basic configuration. Existing BS2000/OSD
applications in the /390 world offer full object compatibility, i.e. they require no modifications,
when run on the SPARC64 architecture of the SX servers.
The SX server hardware is based on the PRIMEPOWER server hardware. The business
servers in the SX series can be divided into two classes: on the one hand the partitionable
models, with facilities for using several separate runtime environments for BS2000/OSD
and Solaris™applications, and on the other hand the entry-level models without partitioning
which offer a cost-effective way of entering the SX server series.
The hardware of the partitionable models is designed so that existing hardware compo-
nents (CPU, main memory, controllers, disks, etc.) can be distributed across multiple parti-
tions. This means that different, independent operating systems together with their available
applications can be run on separate partitions. These operating systems and applications
do not affect each other when they are running.
With their high availability and scalability, and the capacity for the parallel operation of
several independent application environments, the partitionable SX server models provide
an optimum basis for enterprise and business applications and for server and storage
consolidation. At the same time they also open up the SX series to the varied application
environment of the Solaris™operating system.
The SX100 series models are the entry-level models of the SX series. These non-partitio-
nable models are designed exclusively for use with BS2000/OSD. The SX series entry-level
models with their high availability and favourable total-cost-of-ownership (TCO) form an
optimum basis for the BS2000/OSD entry-level both for proven enterprise applications and
for new enterprise and E-business solutions.

Preface
All SX series models have the latest processor technology and optional fibre channel
interface technology for fibreCAT disk systems with possible SAN integration. These
features ensure that SX series models are a future-safe investment.
Figure 1: Example of an SX server: SX150 Business Server
On the business servers in the SX series suitable redundancy facilities result from the
operation of several partitions. These facilities are explained in more detail in the manual
“SX Series Business Servers – Concepts and Functions” [1].
Moreover, almost all functional elements can optionally be designed and configured redun-
dantly on an SX server (console interfaces, disks, power supply, peripherals, etc.).
Business servers in the SX series have the following partitions according to the operating
system being run:
●BS2000 partitions
The BS2000/OSD operating system is installed with the X2000 carrier system. X2000
is based on Solaris and essentially provides the runtime environment for BS2000/OSD.
As an alternative to the native operation of BS2000/OSD, depending on the model up
to 15 independent BS2000/OSD guest systems can be operated under VM2000.
●Solaris partitions
The Solaris operating system is installed.
Each partition can be set up either on the basis of the physical partitioning PPAR or on the
basis of the extended partitioning XPAR. You will find more details on this in the appendix
(page 385ff).

U41272-J-Z385-3-76 3
Preface
X2000 is based on the Solaris operating system and provides the following functions:
●HAL (Hardware Abstraction Layer)
HAL maps the hardware-software interfaces of the /390 mode to equivalent interfaces
of the SPARC64 mode.
●/390 firmware
The /390 firmware component extends the SPARC64 mode and enables existing
customer applications to run object-compatibly on the SX servers under OSD/XC. This
applies both for applications generated with ASSEMBH and also for programs which
were generated with the BS2000 compilers for high-level programming languages. As
of OSD/XC V2.0 and X2000 V3.0A05 the SX servers also support ESA data spaces in
customer applications. Objects which are available in the special RISC object format for
SR2000 must be recompiled. The commands supported by ASSEMBH are described
in the manual “Assembler Instructions (BS2000/OSD)”[16].
●Execution of the inputs/outputs and data communication
●Administration and operation of the SX server
Entry-level models in the SX series
The entry-level models in the SX series are non-partitionable and designed for use exclu-
sively with the BS2000/OSD operating system. BS2000/OSD running on entry-level models
uses the functionality of the X2000 carrier system.
With these models, too, state-of-the-art processor technology, the efficient LTO tape device,
and optional fibre channel connection technology for FibreCAT and Symmetrix disk systems
and for CentricStor and ITC/SBU with SAN integration capability make these servers a
future-safe investment.
You will find more detailed information on the hardware of the different model series in the
appendix (page 385ff).

2 Operating concept of the SX servers
SX servers (with the exception of entry-level models) are operated via the system
management console (SMC) as the central console for the hardware and for the BS2000
and – optionally – Solaris operating systems. The business servers of the SX series, with
the exception of the entry-level models, are therefore also referred to in the following as
“SX servers with SMC”.
A concept has been developed for uniform operation of the different operating systems. This
operation is described in the section “Operating concept for SX servers with SMC” on
page 12.
The entry-level models in the SX series are also operated centrally with the integrated
console or an optional LAN console. For operating the entry-level models see the section
“Remote operation via LAN-PC” on page 16.
Remote administration can be performed from PCs separate from the computer center.
These can be used to administer the server and to configure and operate the instances of
BS2000 (e.g. remote BS2000 console) and, optionally Solaris, on the basis of a uniform
concept.

2.1 Operating concept for SX servers with SMC
The figure below shows the operating concept of an SX server with SMC and a BS2000 and
Solaris partition, taking the example of an SX130 configuration:
Figure 3: Example of an operating concept for an SX server
Up to and including SX140 the SMC for an SX server is based on a PRIMESTATION system
with Solaris 8. The SMC for an SX150 server is based on a PRIMEPOWER250 system with
Solaris 9. The user interface for all functions is the X-Window Common Desktop
Environment (CDE) interface. This is where the System Console Software (SCS) runs. This
is used to administer the hardware functions of the SX system, and in particular the
functions for starting up/shutting down the server and partitioning the system.
The DVD/CD-ROM drive of the SMC can be used across partitions. In this way, operating
systems and applications can be installed in every partition of the SX server.

Operating concept of the SX servers Operating concept for SX servers with SMC
System administration of X2000 functions (and optionally, Solaris functions) can be
performed from any client via the PRIMEPOWER ServerView graphical user interface. To
do this, you will need a Web browser which has Java support. The SMC server names and
the names of all the partitions present on the SX server must be entered in the DNS. The
PRIMEPOWER ServerView application Domain makes it possible to perform administration
tasks outside of the local system. This means that administrators can administer clusters of
systems as a single system. So it is not necessary to perform each action for every system
individually and helps avoid errors.
The Domain application can support multiple BS2000/OSD instances and Solaris partitions
in a single PRIMEPOWER ServerView session.
The BS2000 console and dialog can be operated in the dtterm terminal emulation mode of
the X-Window CDE interface. The X2000 applications KVP software and 9750 emulation
provide the necessary functionality.
The individual SMC functions are described in detail in chapter “Functions of the System
Management Console” on page 43ff.

Figure 4: Operating concept of an SX server without SMC
An SX server entry-level model is operated as standard via the integrated console. The
operator interface for all functions is the X-Window interface CDE of the Solaris/X2000
carrier system. Here the interface provides functions for all the instances to be operated,
such as BS2000 console, BS2000 dialog, X2000 configuration and hardware adminis-
tration.
Hardware components consist of a DVD/CD ROM drive for installing the operating system
and applications, and a DAT drive for backup purposes.

2.2.1 Operation with integrated console
The entry-level models are operated from an integrated console with screen, keyboard and
touchpad installed in a rack.
The console is a Solaris console device on which the messages of the Solaris and the
X2000 carrier system can be monitored when starting up the server (e.g. after switching
on). This therefore gives you access to the OpenBoot PROM.
The console also provides the user interface for all the required functions after starting up
the server. The individual functions are described in detail in the chapter “Functions of the
SX server entry-level models” on page 125.
2.2.2 Operation with a LAN console and remote console adapter
The figure below shows an operating concept for an entry-level model with a LAN console
and a remote console adapter:

Remote operation via LAN-PC Operating concept of the SX servers
The LAN console is available for administering UNIX/Solaris midrange servers and
SX server entry-level models from Fujitsu Siemens Computers Gmbh. The LAN console
has the following features:
●It supports the installation, configuration, administration and diagnostics management
of one or more connected SX server entry-level models, RM servers and
PRIMEPOWER servers.
●The LAN console can be used to perform all the functions of a character-orientated
screen, including the OBP monitor and a reboot of the system.
●The selection and display of one or more consoles of SX, RM and PRIMEPOWER
servers are performed by the tool xscon.
●Support of PRIMEPOWER ServerView (Web-based system administration).
●The SX server entry-level models and RM and PRIMEPOWER servers can also be
booted remotely (via LAN).
●The Teleservice connection for all systems is available centrally on the LAN console.
2.3 Remote operation via LAN-PC
If remote operation of the SX server is required, it is possible to use PCs with a network
connection to the server's SMC.
If an X server is employed, then it is possible to make use of the SMC user interface. This
means that it is possible to access the System Console Software (SCS) using the same
interface as is available directly at the SMC.
Administration of the SX business server partitions using PRIMEPOWER ServerView is
possible either by calling PRIMEPOWER ServerView in the CDE user interface, via the
Start button, via an icon on the desktop, or directly in the PC's browser. The BS2000
console and dialog can be operated in the SMC dtterm windows.
Alternatively, SINIX-TE can be used as a 97801 emulation in order to provide support for
Fujitsu-Siemens emulation keyboards for BS2000 (this is not possible when establishing a
communication using the Secure Shell).
If an SKP-SR is present, then this can also be used to provide support for 97801 emulations
for BS2000 console and dialog access (this is only released on SX130 servers but cannot
be used for communication when the Secure Shell is employed).
For further information on hardware and software requirements as well as on configuration,
refer to chapter “Remote operation via PC” on page 133ff.

U41272-J-Z385-3-76 17
Operating concept of the SX servers Notes on security
2.4 Notes on security
With an SX business server you can connect multiple systems to each other to form an
operating cluster. Entry-level models in addition to the operating system BS2000/OSD now
have the carrier system X2000 available as an additional system. This means that for
administration and operating purposes you will require access to a number of different
logins. The access to these logins (and in particular to the root login) has security-related
implications. The sections below provide some notes on access control.
2.4.1 Passwords
The business servers in the SX series are shipped with standard passwords for access to
the X2000 carrier system, Solaris (in the case of Solaris partitions) and the SMC.
These passwords must be changed by the customer, particularly for the root logins
on the corresponding systems!
When assigning passwords, we recommend that you follow these general rules:
– Passwords must be changed at regular intervals.
– Passwords can contain characters, figures and special characters.
– Passwords must not be stored on the system or on the remote workstations.
2.4.2 Login access to root in the partitions
In the SX business server as it is supplied, root access to the partitions is possible only via
the console, either on the SMC (see section “Consoles of the partitions with RC2000” on
page 86) or, for entry-level models, on the local console.
In the system as supplied, a remote login to the root login via a network is therefore not
possible.
This is achieved by setting CONSOLE= dev console in the file etc default login.
This entry must not be changed into a comment!
Generally speaking, it is not necessary to possess login access to the root login in order to
administer partition systems (of, for example, entry-level models) because PRIMEPOWER
ServerView is provided for this purpose. This is particularly true in the case of BS2000
systems.
i
i

18 U41272-J-Z385-3-76
Notes on security Operating concept of the SX servers
However, should it become necessary to work under the root login then it is advisable to set
up user-specific logins under which login can be performed. Only then should the user
acquire root permissions by means of the su command.
User-specific IDs can be set up in the Users application of PRIMEPOWER ServerView in
the Users tab by clicking on the Users button and selecting the Create function (for details
please see the section “Administration of PRIMEPOWER ServerView” on page 53).
The advantage of this procedure is that root requests are logged in the sulog file. This
ensures that there is a record of when which users have acquired root permissions.
2.4.3 FTP access to root
This is similar to login access. File transfer with root permissions also calls for certain
security-related considerations. For this reason, FTP access to root is not possible by
default. This is achieved by setting root in the file etc ftpusers.
This entry must not be changed into a comment!
It is better to start by performing the transfer under a user-specific login. As described
above, the files can then be copied to the target location by using the su command with the
appropriate authorizations to request the root permissions.
2.4.4 User roles for SX servers with SMC
Depending on the extent to which it is necessary to separate Solaris and BS2000 adminis-
tration and operation, there are a number of different ways of performing these tasks.
A number of related scenarios are presented below:
●Joint administration of the server, the configuration and operation by system adminis-
tration
In the simplest case all the server administration tasks are performed by a restricted
user group. In this case, all the members of this user group are able to access the SMC
from where they perform all the necessary tasks.
The SMC is not accessed via the root login but under one or more server administrator
logins belonging to the cladmin group (see section “User groups and logins” on
page 44).
i

U41272-J-Z385-3-76 19
Operating concept of the SX servers Notes on security
●Separate server administration and partition administration
Each partition on the SX server can have its own partition administrator. The partition
administrator possesses the rights necessary to switch the partition on and off and
access the partition's hardware console.
For information on setting up a login for a partition administrator, refer to section “User
groups and logins” on page 44. This login is a member of the clmon group and a partition
administrator group that you will need to create.
●Administration of operating systems in partitions without partition administration rights
If necessary for the purposes of operating system administration and operation, it is
possible to create logins which do not possess any extended rights for the adminis-
tration of the server or the partitions. These logins should be members of the clmon
group in order to ensure that the SCS read access functions are available at the
partition's hardware console. For more information, see section “User groups and
logins” on page 44.
The following logins have already been created as supplied to manage the server
on the SMC:
– A server administrator login sxadmin
– A partition administrator login bs2admin for the BS2000 partition
– A partition administrator login soladmin for any Solaris partitions present
It is recommended that you use these logins to administer the server.
2.4.5 Security when accessing BS2000 operation functions
The following protective mechanisms can be set up when configuring BS2000 console
access:
BS2000 operation is performed via a login in X2000 for which a separate password is
required. This password must be subject to the usual password maintenance rules. The
logins from cons0 to cons7 are provided as default for this purpose. The administrator
defines any additional logins via PRIMEPOWER ServerView.
Running operator terminals (BS2000 consoles) can be secured via the main KVP function
menu (see the section “The Main KVP Function Menu” on page 164) by locking the inputs
on the BS2000 system. To reset this lock, it is necessary to enter the password. This does
not affect message output.
i

20 U41272-J-Z385-3-76
Notes on security Operating concept of the SX servers
To connect additional operator terminals via LAN, it is always necessary to enter a
password.
All the inputs and outputs can be recorded in a logging file and then archived. In the case
of high security requirements, the option for both logging and archiving should be set to
FORCED. These settings are made in the Bs2Devices application of PRIMEPOWER
ServerView by clicking on the BS2-KVP tab, selecting the first entry for a KVP name,
clicking with the right mouse button, and selecting the function “Show or modify logging
options”.
Activating these options also has the effect of recording all inputs and outputs in the
logging file. This results in an increase in the size of the logging file. You should
therefore check the size of the logging files and free space in the file system at
regular intervals.
2.4.6 Secure access with Secure Shell (open SSH)
Where tight security for the remote operation of SX series business servers is specified,
Secure Shell (SSH) is an ideal solution for secure remote logins, executing commands, and
file transfers for administration purposes.
The most commonly used and most widespread application of Secure Shell is the secure
remote administration of servers in business networks. The Secure Shell protocol is used
worldwide on innumerable systems and Secure Shell technology has been developed as a
de facto standard in the area of application connection.
Secure Shell is an application which protects TCP/IP connections between two computers.
The connection is coded on the application layer, which means that the security provided
by Secure Shell is independent of the type or speed of the network connection.
In the business servers in the SX series Secure Shell is used for the connection between
the administration PC and the system management console (or the server directly in the
case of the entry-level models) and also the partitions.
The product OpenSSH is used on the BS2000 partitions, the Solaris partitions with a
Solaris version up to and including V8, and the SMC of the partionable servers up to and
including SX140. The Secure Shell Software from Sun which is integrated into Solaris from
V9 on is used on Solaris partitions with a Solaris version as of V9, and the SMC as of the
SX150 model series. Both products support both Version 1 and Version 2 of the SSH
protocol.
