Overview of Partition System Booting
This section provides an overview of the Partition system boot process for HP Superdome 2
systems. On HP Superdome 2 with enclosures and blades, system resources are configured into
one or more nPartitions. The nPartitions may be further divided into virtual partitions (vPars).
Each nPartition includes the blades (with processors and memory) assigned to it and the I/O
expansion enclosure with I/O bays. Each vPar includes CPU cores, memory, and I/O that may
be addressed at the individual slot level.
A Partition (nPartition or vPar) can boot and reboot independently of any other Partitions in the
same server complex. Each Partition runs its own firmware and has its own system boot
environment. Partitions provide hardware and software fault isolation: a reset, TOC, or MCA
in one Partition does not affect any other Partition. The OA provides commands to boot a partition.
An nPartition provides a platform for booting an operating system that is electrically isolated
from other partitions in the complex. You can choose to run either a single OS instance, an
Integrity VM host (and guests), or vPar in any nPartition.
Accessing the OA
You can configure and manage partitions using the Onboard Partition Manager.
The Onboard Partition Manager is a set of tools integrated with the HP Superdome 2 Onboard
Administrator. The tools consist of both command line and graphical user interfaces. The Onboard
Administrator Partition Management GUI replaces the legacy ParMgr GUI which ran on an
operating system in a partition. The Onboard Partition Manager tools are a complete set of
nPartition and vPar configuration and management tools providing nPartition and vPar
configuration information as well as many other enhancements over the previous GUI tool. The
OA GUI is accessible from the partition side through SMH.
OA CLI
To launch the OA CLI, complete the following steps:
1.
To access the OA CLI, use a telnet or an ssh connection to the OA address.
2.
Enter the OA Administrator password.
NOTE:
The original Administrator password is available on a sticker on the OA module.
