Installing and Managing HP-UX Virtual Partitions (A.02.01)

Introduction

Supported Environments

Chapter 126

• PCI OLAR (On-Line Addition and Replacement)

OLAR for PCI slots works the same on a vPars server as it does on a

non-vPars server. However, you can exeucte OLAR functions only on

the PCI slots that the virtual partition owns.

• MC/ServiceGuard

MC/ServiceGuard is supported with vPars. However, because

MC/ServiceGuard is used to guard against hardware failures as well

as software failures, its functionality will be reduced if a cluster

includes multiple virtual partitions within the same server. Such

conﬁgurations are not recommended. See the MC/ServiceGuard

documentation for more information on running MC/Service Guard

with vPars.

• Glance and Openview Performance Agent (MeasureWare)

For correct reporting of CPU utilization, you need to run Glance and

MeasureWare versions C.03.35.00 or higher.

• WLM (Workload Manager)

If you have iCOD or PPU software installed, do not use WLM’s vPar

(virtual partitions) management. Using WLM’s vPar management in

such an environment may cause an iCOD processor to be

automatically enabled without customer authorization. If this

situation occurs, please contact your HP representative.

• PSets (Processor Sets)

In the current release of vPars, you cannot specify a hardware path

for an unbound CPU. Therefore, to avoid unintentionally removing

unbound CPUs from a non-default pset, initially create the partition

that will be running PSets using only bound CPUs. Then, when you

add or remove an unbound CPU, the unbound CPU will be added to

or removed from only the default pset.

• Ignite-UX

For information on a "cookbook" for setting up your Ignite-UX server

for use with vPars, see “Setting Up the Ignite-UX Server” on page 78.

Before using Ignite-UX to install or recover vPars, you may need to

update your Ignite server. For more information, see “Updating the

Ignite-UX Server” on page 79.
