Power Systems: Overview of SDMC
SDMC concepts
The IBM Systems Director Management Console (SDMC) is the next generation Hardware Management
Console (HMC) that combines the functions of the HMC, the simplicity of the Integrated Virtualization
Manager (IVM), and the value-add functions of the IBM® Systems Director. The SDMC provides server
management and PowerVM™ virtualization management.
The SDMC is a management console for managing IBM Power Systems™ servers and IBM BladeCenter®
Power blade servers. The SDMC is an alternative and replacement for the current HMC with enhanced
virtualization and hardware management capabilities. The SDMC is an x86-based console. The SDMC
manages IBM AIX®, IBM i, or Linux operating systems on IBM Power Systems servers and IBM
BladeCenter Power blade servers.

Power Systems: Overview of SDMC
Comparing HMC and SDMC features
You need to understand the differences between the Hardware Management Console (HMC), Integrated
Virtualization Manager (IVM), and IBM Systems Director Management Console (SDMC) environments
including terminology, users and roles, supported features, high availability options, and command-line
differences.
Comparing the HMC and SDMC
There are some important differences between the HMC and the SDMC.
With the SDMC, the scope of administered systems spans from POWER blade servers to high-end
systems, providing a single, consistent approach to systems administration.
The characteristics of both the HMC and the SDMC, at a high level, follow:
HMC
v Is implemented as an external, independent appliance
v Can administer entry-level systems to high-end systems
v Can administer more than one managed system
v Allows for more than one VIOS per managed system
SDMC
v SDMC is offered as an appliance in two forms:
– A hardware appliance similar to the HMC, using essentially the same hardware plus additional
memory and disk.
– A virtual appliance that runs in a VMware partition
v Can administer entry-level systems to high-end systems
v Can administer more than one managed system
v Allows for more than one VIOS per managed system
v Supports entry-level systems to high-end systems plus blades.
How the SDMC is used
SDMC represents the next generation of management appliances for POWER processor-based systems.
The SDMC replaces both the HMC and IVM in POWER processor-based systems administration. Thus,
the SDMC can manage POWER systems directly but can also work with the HMC and IVM side by side
to ease transition.
SDMC is integrated into the administrative framework of IBM Systems Director. It provides a common
interface for systems administration across the data center. If you have used an HMC or IVM, you will
already be familiar with SDMC tasks and procedures. The Systems Director provides additional tasks that
you might want to explore. Note that these additional Systems Director tasks and navigation options
might make it more difficult to find familiar HMC tasks. For more information about navigating the
SDMC GUI, see “Navigation differences between the HMC GUI and the SDMC GUI” on page 7.
The SDMC can unify platform management for IBM Systems, providing a consistent interface for
common management tasks. By integrating POWER processor-based systems management into the IBM
Systems Director framework, you can easily manage many systems of different types. The SDMC also
enables the integration of POWER processor-based systems into data center management tools.

As a successor to both the HMC and IVM, the SDMC administrators can work with a high-level view of
systems. It organizes tasks in a single window, instead of using different menus. This interface simplifies
views on systems and provides faster access to day-to-day tasks.
As it was with older POWER processor-based systems, the transition to the SDMC requires that
management for POWER5 and POWER5+ processor based systems continue with either the HMC or
IVM. The SDMC can administer the HMC and IVM as well; however, this management console eases
transition from older environments into new ones.
Virtualization enhancements
SDMC has made managing your virtualization environment significantly easier, while maintaining all of
the HMC's existing functions.
The enhancements follow:
Virtual I/O management
In addition to the HMC's Virtual Storage Management view, The SDMC brings similar
simplification to the Create Virtual Server and Manage Virtual Server views. With SDMC, you can
see the storage devices attached to a virtual server and need not be concerned about your virtual
SCSI device pairs and the VIOS command-line.
Simplified Create Virtual Server wizard
Create Virtual Server (known as logical partition on the HMC) wizard asks only what is needed
to create the virtual server, and selects reasonable defaults for all other settings. Advanced users
who want full control can change the profile after the wizard is completed to control all of their
settings, such as min/max values. You can now create a virtual server by simply specifying the
name and clicking Finish.
Managing virtual server
A task called Manage Virtual Server displays virtual server properties and I/O device
configuration information in one window. With this task, you control the resource assignments
for a virtual server directly (whether the virtual server is powered on or off) without using a
profile.
Terminology differences between HMC and SDMC
The HMC and SDMC environments use different terminology.
For integration into IBM Systems Director, SDMC introduces some synonyms that replace familiar HMC
terms. The key ones to remember are the following:
v Virtual Server (formerly Partition)
v Host (formerly Managed System or Server)
v Power Unit (formerly Frame)
For detailed information about the terminology differences between the HMC and the SDMC, see the
following tables.

Navigation differences between the HMC GUI and the SDMC GUI
This section describes the differences in navigating to commonly used Hardware Management Console
(HMC) tasks on the HMC and on the Systems Director Management Console (SDMC).
Because IBM Systems Director manages many different types of objects, it has a generic navigation style.
Systems Director groups managed objects and shows general properties for each object. The SDMC
interface is quite similar to the HMC interface.
Below is a list of commonly-used HMC tasks, and where they can now be found in the SDMC interface:
Viewing host (server) properties by using the SDMC interface
The Properties task in SDMC is different from that of the HMC. The SDMC now calls a server a host.
To view server properties by using the HMC, complete the following steps:
1. In the navigation pane, selectSystems Management.
2. Select the server.
3. In the contents pane, select Tasks > Properties.
To view host properties by using the SDMC, complete the following steps
1. From the Resources page, right-click the host.
2. Select System Configuration > Edit Host.
Viewing virtual server (partition) properties by using the SDMC interface
To view partition properties by using the HMC, complete the following steps:
1. In the navigation pane, selectSystems Management.
Comparing HMC and SDMC features

2. In the contents pane, expand the server.
3. Select the logical partition.
4. Click Tasks > Properties.
The SDMC now calls a partition a virtual server.
To view virtual server properties using the SDMC, complete the following steps:
1. From the Resources page, select the virtual server.
2. Click System Configuration > Manage Virtual Server.
Discovering a system to manage using the SDMC interface
Discovery is a general Systems Director concept of finding a system or object to manage. You can use the
SDMC interface to discover and manage the following objects:
v Host flexible service processors (FSPs) and host power units
v Bulk power controllers (BPCs) and frames
v Operating systems
If you are using the SDMC as a Dynamic Host Configuration Protocol (DHCP) server for your managed
systems, the FSPs and BPCs are discovered automatically. If you are not using the SDMC as a DHCP
server, you can discover the resource by entering a host name, an IP address, or a range of IP addresses
in the Discover section of the GUI or the command-line interface (CLI).
To discover a system to manage by using the HMC, complete the following steps:
1. In the navigation pane, selectSystems Management.
2. Select the server.

Comparing HMC and SDMC features
23
Functional differences between the HMC, IVM, and SDMC
There are functional differences between the Hardware Management Console (HMC) and Integrated
Virtualization Manager environments and the Systems Director Management Console (SDMC)
environment.
The SDMC incorporates most functions of the HMC. This has been done through direct mapping of
commands or by replacing functions that are present already in IBM Systems Director. Some functions are
not currently available for the SDMC, such the ability to handle system plans. For a complete listing of
functions, see Comparing HMC tasks and SDMC tasks
Although the SDMC retains most of the functions that are available in the HMC, a few functional
differences exist between the SDMC and the HMC. These differences are directed toward adapting to the
IBM Systems Director environment and also toward improving the user interface.
The command-line interface (CLI) is essentially the same. On the SDMC, most of the commands are just
preceded by smcli. This might require changes to existing scripts that use the HMC.
Enhanced virtualization management
The following are some of the key enhancements in virtualization management that are available in the
SDMC:
v SDMC offers a simplistic IVM kind of user interface for virtualization functions, such as creating a
virtual server.
v The views of virtual server properties and dynamic logical partitioning (DLPAR) are combined to
present a single view from where you can perform all virtual server operations.
v SDMC provides the ability to change the resource assignment of your virtual servers even when they
are in the Stopped state.
v SDMC can manage virtual slots automatically.
Users and roles
The concepts of users and roles in the SDMC remain the same as in the HMC. The user interfaces for
creating and managing users and roles are different in the SDMC. SDMC follows the IBM Systems
Director way of creating and managing users and roles. SDMC supports the use of LDAP and Kerberos
servers. You can create users who use Lightweight Directory Access Protocol (LDAP) or Kerberos for
authentication. Resource roles in HMC are referred to as groupsin SDMC. Also, the session time-out and
the idle time-out settings are global and not configured per user.
For more information about user and roles in the SDMC environment, see Predefined user IDs and
passwords and SDMC roles
User interface enhancements
SDMC provides a user interface that is integrated with the broader IBM Systems Director user interface.
Most of the tasks in SDMC have the same flow as in the HMC with slight enhancements to present an
IBM Systems Director appearance.
Redundancy model
The existing redundancy model available in HMC is available in the SDMC as well. You can connect two
SDMCs to a managed system in which one of the SDMCs acts as the redundant SDMC. You can also use
an HMC for redundant management. Apart from this redundancy model, IBM Systems Director provides
an active-passive availability model that is optional for the SDMC users. In this model, two SDMC nodes
can manage a single server, of which one node is used (active) and the other is not used (passive),
24
Power Systems: Overview of SDMC
waiting for a failover condition. The existing HMC active-active redundancy model is available in
addition to the active-passive availability model, both provided by the IBM Systems Director.
Backup and Restore
SDMC provides the capability to back up the entire virtual machine to removable media or to a remote
File Transfer Protocol (FTP) server. You can restore using the backup file from the removable media or
from a remote FTP server. The restore operation is a full image deployment and all existing files are
replaced from the backup file. Unlike the HMC, SDMC backs up the entire disk instead of individual
files.
For more information about performing a backup and restore of the SDMC environment, see Backing up
and restoring the SDMC
Additional functions
The SDMC includes the IBM Systems Director base management functions which offers you additional
capabilities to manage your heterogeneous and large homogeneous infrastructure better. These
capabilities include:
v Automation manager
v Update manager
v Status manager

SDMC redundancy and high availability features
Implementing SDMC in a high availability (HA) or a redundant setup can provide improved
serviceability to the SDMC appliance and provides backup to the system in case of a disaster.
SDMC HA versus redundant setup
If you are familiar with redundant HMC setup in your Power Systems environment, you can do the same
with SDMC, because multiple SDMCs can connect to and actively manage a single host.
For more information about the tasks associated with SDMC redundancy and high availability, see SDMC
installation and configuration scenarios and Configuring high availability.
You can also implement SDMC HA, which provides active/passive failover capability, with one active
SDMC and one passive SDMC on standby to take over in case of failure.
In addition to providing the management capabilities currently in the HMC for the managed Power
Systems hosts, the SDMC also can manage the operating systems of the hosts themselves by connecting
to the Common Agent Services (CAS) agent on the managed systems through an agent manager.
However, the CAS agent has the limitation of only a single connection to an agent manager and is not
capable of a redundant connection. Therefore, the SDMC HA feature is provided to eliminate this
limitation as a single point of failure if you require high availability for this functionality.
The choice between a redundant setup versus an active/passive HA implementation depends on your
planned usage of the SDMC:
v In an environment where the SDMC is being used for HMC-like management functions, the redundant
setup provides the most availability and is the easiest to set up and administrate. Both SDMCs will be
active and can continue to provide functions for the managed systems should one of them have a
failure. The setup of a redundant SDMC environment only involves adding the managed system to
both SDMCs.
Comparing HMC and SDMC features
27
v For an environment where the SDMC is being used for agent OS management and there is a high
availability requirement for that function, SDMC HA is needed. If your active SDMC fails, the passive
standby SDMC automatically takes over and management functions for the managed systems are
restored in about 10 minutes. Some extra planning, setup, and administrative steps are required to
implement SDMC HA. For more information about the planning tasks associated with implementing
high availability, see Planning for high availability, redundancy, and failover.
The following table shows the differences between redundant HMCs and IBM Systems Director high
availability setup.

In a redundant setup, it is also possible to have one SDMC point to another SDMC's agent manager,
which would allow both SDMCs to manage the agents at the same time. However, since the agent
manager is running on only one of the SDMCs, this setup is a single point of failure. If this SDMC goes
down, the other SDMC loses contact with the agents.
Active/passive HA overview
In a high availability environment, two SDMCs operate as synchronized nodes in an active/passive
cluster. One node in the environment is kept active at all times, and a second passive node is kept in
close synchronization. If your active node fails, the passive node (on standby, waiting for a failure of the
active node) takes over in about 10 minutes.
The internal software components that make up SDMC HA are transparent to you and do not need to be
directly configured. Floating IP addresses used to connect to the active SDMC can be moved between the
nodes, by using the active node. The OS on the passive node is started, but the software stack is not.
Running the Guided Setup wizard or the command-line interface commands on the SDMC that is
designated to be the primary node configures the internal HA components on both the primary and
secondary SDMCs.
High availability terminology
Refer to this list of terms to help you better understand high availability concepts:
Node
A node is an SDMC that is configured to be part of a high availability environment.
Active node
An active node manages your environment. Only one node is active at a time.
Passive node
The passive node is not currently active. Any changes you make to the active node are replicated
to the passive node.
28
Power Systems: Overview of SDMC
Primary node
This is the node you use to set up high availability. It is initially the active node. When you set
up a high availability cluster, the IBM Systems Director data, remote authentication configuration
settings, users, and firewall settings on this node are replicated to the secondary node.
Secondary node
This is the node that you set up to take over if the primary node fails. It is initially the passive
node, but takes over as the active node if the primary node is detected to have failed.
Network status IP address
The cluster nodes use this IP address to determine which node is connected to the network. If
they cannot contact each other, the node that can connect to this IP address becomes the active
node.
Floating IP address
This address is always assigned to the active node. Always access this address so that you do not
have to know which node is active. It also enables you to use IBM Systems Director Common
Agent with high availability.
Active/passive HA mirrored directories

SDMC and HMC command-line differences
There are differences between the HMC commands and the SDMC commands.
Commands used to manage the Power Systems servers such as lssyscfg, lshwres, and chhwres that are all
supported and virtually identical to the commands in the HMC. Any scripts that you may have that use
these commands should continue to work with no changes.

Power Systems: Overview of SDMC
To see all of the HMC commands that are supported on the SDMC, run the smcli lsbundle command.
The commands that have been carried over from the HMC are in the psm bundle.
The following topic describes how to run SDMC commands. Commands for managing Power Systems
resources can be run in exactly the same way as on an HMC. However, to integrate into the Systems
Director way of doing commands, there are additional ways to issue commands. The following
commands are all equivalent:
v lssyscfg –r sys
v smcli lssyscfg –r sys
v smcli psm lssyscfg –r sys
v The commands that have been carried over from the HMC are aliased. Therefore, you can run the
command in three ways from the command line: lssyscfg, smcli lssyscfg,, or smcli psm lssyscfg .
v Add managed system (mksysconn) in SDMC has been replaced by the smcli discover and smcli
accesssys Systems Director commands.
v Two attributes, primary_state and detailed_state, are introduced to the lssyscfg and lssysconn
commands to indicate the respective Systems Director state mapping. The state field is deprecated. It is
only shown when the -F option is used.
v Man pages for the SDMC commands can be displayed by running either man command_name or man
psm.command_name.
The following tables compare HMC command-line interface (CLI) function with SDMC CLI function.
These tables display only the changes, and all functions not shown can be assumed to be similar.

Notes
Add Managed System: mksysconn –r
sys/frame
smcli discover –H smcli accesssys
Discover and access are two separate
steps on SDMC. Make sure you
specify the IP or hostname in SDMC;
otherwise, by default, it discovers
everything on your subnet. If SDMC
is acting as the DHCP server, systems
must be automatically discovered.
You must request access.
Remove Managed System: rmsysconn
–o remove
smcli rmsys
You can disconnect by using the
smcli revokeaccesssys command;
however, to completely remove the
system, you must use smcli rmsys.
List system or partition states:
lssyscfg –r sys/lpar –F state
lssyscfg –r sys/lpar –F
primary_state,detailed_state
Although the HMC state option is
supported, to view the states as the
SDMC GUI displays them, you need
to view the primary_state and
detailed_state.
