•
If running Partition Manager on another system (not an nPartition):
Partition Manager automatically displays the
Switch Complexes
dialog. Enter the
hostname or IP address of the MP in the target complex, and type that MP’s IPMI
password.
Running nPartition commands using IPMI over LAN
To run nPartitions
commands remotely using IPMI over LAN, you must include two command-line options
with each command:
•
-g [password]
The
password
is the management processor’s IPMI password.
•
-h hostname | IPaddress
The
-h
option specifies the hostname or IP address of the management processor in
the target complex.
When you use the
-g... -h...
set of options, the command sends appropriate WBEM
requests to the local nPartition Provider, which in turn uses IPMI over LAN to
communicate with the management processor in the target complex.
Web-Based Enterprise Management (WBEM)
Web-Based Enterprise Management (WBEM) is an industry initiative that establishes
management infrastructure standards and provides a way to combine data from various
hardware and software management systems. WBEM specifies standards that enable
access to data from various technologies and platforms, and the presentation of that data
in a consistent fashion. Client applications can then use this information to manage an
enterprise computing environment.
Because WBEM supports a distributed management architecture, client applications
(nPartition management tools, for example) can run on a remote system and use the
WBEM infrastructure to send requests to the managed servers.
Partition Manager is one such WBEM client application. Partition Manager uses WBEM
when retrieving information about a server complex. Partition Manager uses the
nPartition commands for all other operations. The nPartition commands are also WBEM
client applications.
The nPartition commands for Windows are supported by several software components.
The Windows operating system provides the Windows Management Instrumentation
(WMI) software, which is an implementation of the WBEM standards. HP provides a
WMI-based nPartition Provider and WMI Mapper for converting CIM/XML WBEM
requests from clients (like the nPar Commands and Partition Manager) into WMI
requests.
The nPartition commands and Partition Manager send management messages to the
nPartition Provider. The nPartition Provider handles all communication with the MP
using the IPMI protocol, either locally via an IPMI/BT device driver, or remotely using
the MP's IPMI/LAN interface.
Securing the WBEM connection
WBEM secures the management connection using an SSL authentication process, which
involves the following files:
