Managing Npartitions Using Ipmi Over Lan; Running Partition Manager Using Ipmi Over Lan; Running Npartition Commands Using Ipmi Over Lan; Wbem - HP Integrity rx7620 Installation Manual

The nPartition Provider caches the static data and reuses it for subsequent requests so that future
command usage does not incur that initial overhead. If the PC is rebooted or the nPartition
Provider is restarted, the cached data is lost. The first request to the MP after the restart requires
the same initial overhead.
IPMI specifies that data be sent as UDP datagrams over the LAN. UDP does not guarantee
delivery of datagrams. If datagrams fail to arrive in a reasonable amount of time, the nPartition
Provider retries a number of times. But if the network connection between the PC and MP is too
unreliable or too slow, the provider times out and returns an error. The error is often seen as the
message: [X] data is not available, where [X] is a cell, I/O chassis, cabinet, or other
element in the complex.
The speed and reliability of the network between the management station and the MP has a large
effect on the reliability of command execution. When managing remotely using IPMI over a
LAN, place the management station on the same subnet as and physically close to the target
complex. If you cannot access the management station directly, you can use a Remote Desktop
application or equivalent tool to connect to it from a remote terminal.

Managing nPartitions Using IPMI over LAN

Using IPMI over LAN, you can manage remote nPartitions through the MP. The management
tool on the management station communicates directly with the local nPartition Provider. The
nPartition Provider then communicates with the MP on the remote complex using IPMI over
LAN.
NOTE:
You must use IPMI over LAN to manage nPartitions remotely if none of the nPartitions
on the target server have been booted or configured yet.
To use IPMI over LAN, you must enable IPMI LAN access at the MP, set the MP IPMI password,
and install the nPar tools on your management station. You can then use any nPartition
management tool to manage remote nPartitions.

Running Partition Manager Using IPMI over LAN

You can run Partition Manager using IPMI over LAN in one of two ways:
• When running Partition Manager on an nPartition: From the Tools menu, select the Switch
Complexes task. In the Switch Complexes dialog, enter the host name or IP address of
the MP in the target complex, and enter the IPMI password for that MP.
• When running Partition Manager on another system (not an nPartition): Partition Manager
automatically displays the Switch Complexes dialog. Enter the host name or IP address of
the MP in the target complex, and enter the IPMI password for that MP.

Running nPartition Commands Using IPMI over LAN

To run nPartitions commands remotely using IPMI over LAN, you must include the following
command-line options with each command:
•
-g [password]
The password is the IPMI password for the MP.
• -h hostname | IPaddress
The -h option specifies the host name or IP address in the target complex.
When you use the -g... -h... set of options, the command sends WBEM requests to the local
nPartition Provider, which uses IPMI over LAN to communicate with the MP in the target
complex.
