Introduction Choosing a management mode Choosing a management mode As stated previously, the most common method for managing nPartitions involves a remote management station. This dedicated management station hosts the management tools and issues commands over a network connection to the server's management processor, allowing the complex to be managed even if no nPartitions exist on the complex yet. This is called the "remote management" mode. The other option is to install the nPar tools onto an existing nPartition on the server, and then use them to manage the other nPartitions in the system. This is called the "local management" mode. When the nPar tools run on an nPartition in the local mode, they default to managing the local complex using the IPMI/BT interface to the MP. This may be the simplest mode to use. Since the tools run on the system being managed, there is no need to provide additional authentication/remote connection information to make them work. For example, when running the nPartition Commands in the local mode, no -g, -u, or -h options are required to manage the local complex. And when running Partition Manager in the local mode, the connection to the local complex is made automatically (no additional connection/authentication information is required). Interestingly, it is even possible to manage another complex remotely, from an nPartition configured to run in the local mode, by using the -g or -u options with the nPartition commands, or by using a Tools > Switch Complexes menu path in Partition Manager. A list of the advantages and disadvantages of the different management modes and connection methods follows. Also included are a listing of the authentication and authorization issues associated with each mode. Local management Some of the advantages of local management are: • Simple installation: install all components on an nPartition (also, fewer components need to be installed manually when reinstall media is used). • Simple connection: login to SMH and run Partition Manager; or, run nPar Commands with no -g/-u options. No additional authentication/login steps are required to manage the local complex. • Allows configuration of specific nPartitions to be controlled by use of the nPartition Config Privilege option (users can be restricted to configuration of certain nPartitions). Some of the disadvantages of local management are: • Requires at least one nPar to be configured already and booted to Windows (or other OS supporting the nPar tools). • Requires nPar tools to be installed on at least one nPar in each partitionable complex. • Requires login to an nPar in each complex to be managed, either via the SMH web (in the case of Partition Manager) or telnet or Remote Desktop (in the case of the nPartition Commands).

Choosing a management mode
As stated previously, the most common method for managing nPartitions involves a
remote management station. This dedicated management station hosts the management
tools and issues commands over a network connection to the server’s management
processor, allowing the complex to be managed even if no nPartitions exist on the
complex yet. This is called the “remote management” mode.
The other option is to install the nPar tools onto an existing nPartition on the server,
and then use them to manage the other nPartitions in the system. This is called the
“local management” mode.
When the nPar tools run on an nPartition in the local mode, they default to managing
the local complex using the IPMI/BT interface to the MP. This may be the simplest mode
to use. Since the tools run on the system being managed, there is no need to provide
additional authentication/remote connection information to make them work.
For example, when running the nPartition Commands in the local mode, no
-g
,
-u
, or
-h
options are required to manage the local complex. And when running Partition Manager
in the local mode, the connection to the local complex is made automatically (no
additional connection/authentication information is required).
Interestingly, it is even possible to manage another complex remotely,
from
an
nPartition configured to run in the local mode, by using the
-g
or
-u
options with the
nPartition commands, or by using a
Tools > Switch Complexes
menu path in Partition
Manager.
A list of the advantages and disadvantages of the different management modes and
connection methods follows. Also included are a listing of the authentication and
authorization issues associated with each mode.
Local management
Some of the advantages of local management are:
•
Simple installation: install all components on an nPartition (also, fewer components
need to be installed manually when reinstall media is used).
•
Simple connection: login to SMH and run Partition Manager; or, run nPar
Commands with no
-g
/
-u
options. No additional authentication/login steps are
required to manage the local complex.
•
Allows configuration of specific nPartitions to be controlled by use of the nPartition
Config Privilege option (users can be restricted to configuration of certain
nPartitions).
Some of the disadvantages of local management are:
•
Requires at least one nPar to be configured already and booted to Windows (or other
OS supporting the nPar tools).
•
Requires nPar tools to be installed on at least one nPar in each partitionable complex.
•
Requires login to an nPar in each complex to be managed, either via the SMH web (in
the case of Partition Manager) or telnet or Remote Desktop (in the case of the
nPartition Commands).
