HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

ILM Interleaved Memory. Is implemented as Partition Memory in HP Superdome 2, which includes
Direct Access Partition Memory and Agent Access Partition Memory
Integrity Virtual
Machines
The HP Integrity Virtual Machines product, which allows you to install and run multiple systems
(virtual machines) on the same physical host system.
Integrity VM See Integrity Virtual Machines..
ISSE HP Instant Support Enterprise Edition. A secure remote support platform for business servers and
storage devices.
localnet A virtual switch created by default when Integrity VM is installed on a VSP. The local network
created by this vswitch can be used for communications among guests but not for communication
between the VSP and any guest or between any external system and a VM guest.
Machine check
abort
See MCA.
MCA Machine check abort
migration The operation of stopping a Serviceguard package on one cluster member and then starting it
on another cluster member. Migrating the package (for example, a virtual machine), can be
useful in system management procedures and workload balancing.
See also virtual machine migration..
multiserver
environment
A Serviceguard cluster consisting of VSP systems.
N_Port ID
Virtualization
See NPIV.
NIC Network Interface Card. Also called “network adapter.”
nPartition A partition that is assigned one or more blades and optionally zero or more I/O bays. An
nPartition can run a single OS (either a standalone OS or an HPVM host), or an nPar can be
sub-divided into customer-defined vPars. An HP Superdome 2 nPar works like an nPar on cellular
servers.
NPIV N_Port ID Virtualization. A Fibre Channel facility allowing multiple N_Port IDs to share a single
physical N_Port.
NSPOF No single point of failure. A configuration imperative that implies the use of redundancy and
high availability to ensure that the failure of a single component does not impact the operations
of the machine.
online VM
migration
Enables a running guest and its applications to be moved from one VSP to another without service
interruption.
OVMM Online VM migration. See online VM migration.
package
configuration script
A script that is customized for each virtual machine Serviceguard package and that contains
specific variables and parameters, including logical volume definitions, for that virtual machine.
package control
script
A script containing parameters that control how Serviceguard operates.
Partition Number A unique numeric value assigned to a partition.
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.
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.
