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

cluster Two or more systems configured together to host workloads. Users are unaware that more than
one system is hosting the workload.
cluster member A cluster node that is actively participating in the Serviceguard cluster.
cluster node A system (VSP or guest) configured to be a part of a Serviceguard cluster.
CRA Critical Resources Analysis.
Deconfigured The term used to describe the health of a resource that has been marked as unusable by the
Health Repository. Such a resource will be excluded from partition activity.
dedicated device A pNIC or storage unit that is dedicated to a specific virtual machine. A dedicated device cannot
be used by multiple virtual machines.
direct I/O
networking
The direct I/O networking feature allows virtual machines to directly control I/O devices.
distributed guests Guests that has been configured as a Serviceguard package.
DLA Device Level Assignment
EFI Extensible Firmware Interface. The boot firmware for all HP Integrity systems.
enclosure An HP BladeSystem c-Class enclosure holds ProLiant and Integrity server blades, storage blades,
I/O option blades, interconnect modules (switches, pass-thru modules, and Virtual Connect
modules), a NonStop passive signal midplane, a passive power backplane, power supplies,
fans, and Onboard Administrator modules.
entitlement The amount of a system resource (for example, a processor) that is guaranteed to a virtual machine.
The actual allocation of resources to the virtual machine can be greater or less than its entitlement,
depending on the virtual machine's demand for processor resources and the overall system
processor load.
event log Information about system events. An event log indicates what event has occurred, when and
where it happened, and its severity (alert level). Event logs do not rely on normal I/O operation.
extensible
firmware interface
See EFI.
failover The operation that takes place when a primary service (network, storage, or CPU) fails, and the
application continues operation on a secondary unit. In the case of Serviceguard virtual machines,
the virtual machine can fail over to another cluster member. In case of a network failure, on a
properly configured system the virtual machine can fail over to another LAN on the same cluster
node.
FLA Function Level Assignment.
Floating memory This is typically used for user applications. You can either add or delete the memory from a live
vPar.
guest The virtual machine running the guest OS and guest applications.
guest administrator The administrator of a virtual machine. A guest administrator can operate the virtual machine
using the hpvmconsole command with action that can affect the specific guest only.
guest application A software application that runs on a guest.
guest application
package
A guest application that has been configured as a Serviceguard package.
guest console The virtual machine console that is started by the hpvmconsole command.
guest management
software
Software that is provided with Integrity VM that you install on the guest to ensure the guest is
manageable by Integrity VM and other components of the Virtual Server Environment and HP
Integrity Virtual Server Manager.
guest operator The administrator of the guest OS. This level of privilege gives complete control of the virtual
machine but does not allow control of the other guests, the VSP, or the backing stores.
guest OS Guest operating system.
guest package A Serviceguard package that is an Integrity VM guest.
host A system or partition that is running an instance of an operating system.1.
2. The physical machine that is the VSP for one or more virtual machines.
