HP-UX vPars and Integrity VM V6.3 Administrator Guide

PMAN Platform Manager. See VSP.
pNIC Physical network interface card.
primary node The cluster member on which a failed-over package was originally running.
redundancy A method of providing high availability that uses multiple copies of storage or network units to
ensure services are always available (for example, disk mirroring).
restricted device A physical device that can be accessed only by the VSP system. For example, the VSP boot device
should be a restricted device.
SAN Storage Area Network.
Serviceguard Serviceguard allows you to create high-availability clusters of HP 9000 or HP Integrity servers.
Serviceguard can be used to manage virtual machines as Serviceguard packages. A Serviceguard
package groups application services (individual HP-UX processes) together and maintains them
on multiple nodes in the cluster, making them available for failover.
Serviceguard node A Serviceguard node, within the Integrity VM context, is a VSP. See VSP.
SGeRAC Serviceguard extension for real application clusters.
SGeSAP Serviceguard extension for SAP.
shared device A virtual device that can be used by more than one virtual machine.
SLM Non-interleaved memory that can be quickly accessed by processors residing on the same cell
as the memory. This is the same concept as CLM.
SLVM Shared Logical Volume Manager.

SSH Secure Shell
start virtual
machines
To start a virtual machine that has been booted before.
See also boot virtual machines.
storage unit A file, DVD, disk, or logical volume on the VSP that is used by the virtual machines running on
the VSP.
symmetric
Serviceguard
configuration
A cluster configuration in which the nodes share access to the same storage and network devices.

VBVsw VLAN-backed vswitch
virtual console The virtualized console of a virtual machine that emulates the functionality of the Management
Processor interface for HP Integrity servers. Each virtual machine has its own virtual console from
which the virtual machine can be powered on or off and booted or shut down, and from which
the guest OS can be selected.
virtual device An emulation of a physical device. This emulation, used as a device by a virtual machine,
effectively maps a virtual device to an entity (for example, a DVD) on the VSP.
virtual machine Virtual hardware system. Also called VM.
virtual machine
application
The executable program on the VSP that manifests the individual virtual machine. The program
communicates with the loadable drivers based on information in the guest-specific configuration
file, and it instantiates the virtual machine.
virtual machine
console
The user-mode application that provides console emulation for virtual machines. Each instance
of the virtual machine console represents one console session for its associated virtual machine.
virtual machine
host
See VSP.
Virtual Machine
Manager (VMM)
The management application responsible for managing and configuring HP Integrity Virtual
Machines.
virtual machine
migration
Migration of a virtual machine from one VSP system to another by using the Integrity VM command
hpvmmigrate. Do not use this command for virtual machine packages.
