Installing and Managing HP-UX Virtual Partitions (includes A.03.03)

Introduction

HP Product Interaction

Chapter 1

However, on a Superdome, the first element of the hardware path is the cell number. So, if

the cell number is 4, the ioscan output shows:

4/0/0 ba Local PCI Bus Adapter (782)

• PCI OL* (On-Line Addition and Replacement)

Except for the function stated below, OL* for PCI slots works the same on a vPars server as it does on a

non-vPars server. Note that you can execute PCI OL* functions only on the PCI slots that the virtual

partition owns.

PCI doorbells (the physical attention button on the system) are supported beginning with the HP-UX

December 20003 HWE release and vPars A.03.01.

(PA-RISC only) In a vPars system, a reboot of the virtual partition does not power on a slot that was

powered off prior to the reboot. If you wish to power on the slot, you need to power on the slot manually

after the reboot using the rad command: rad -i slot_id.

For changes in the use of OLAR on HP-UX 11i v2 (11.23), please see the 11.23 OLAR documentation at

http://docs.hp.com.

• iCAP (Instant Capacity, formerly known as iCOD (Instant Capacity on Demand)) and PPU (Pay Per Use)

iCAP allows online activation of iCAP CPUs; PPU allows purchasing CPU time of processors.

iCAP or PPU and vPars version information:

— Beginning with vPars version A.04.01, vPars now supports PPU Active CPU as well as PPU Percent

Utilization)

— For more information on using iCAP B.07.00 with vPars A.04, “CPU: Using iCAP (Instant Capacity on

Demand) with vPars (vPars A.04 and iCAP B.07)” on page 195.

— If you are using WLM, iCOD, and vPars A.03.02 or earlier together, please see the HP-UX Virtual

Partitions Ordering and Configuration Guide for information on software version requirements.

— Beginning with vPars A.02.01 and iCOD B.05.00, iCOD is now supported in a vPars environment.

— Beginning with vPars A.02.01, PPU Percent Utilization is now supported in a vPars environment.

— For iCOD/PPU versions prior to version B.05.00, vPars can be installed successfully only if all CPUs

in the server are activated (in other words, purchased). Likewise, on a vPars server, iCOD/PPU will

not load or run with versions prior to B.05.00.

— To determine your current version of iCAP, iCOD, or vPars, use the command swlist.

For information on iCOD and LPMC_Monitor, please see the note “Support Tools” on page 23.

• Workload Manager (WLM)

If you are using WLM, iCOD, and vPars together, please see the HP-UX Virtual Partitions Ordering and

Configuration Guide at http://docs.hp.com/hpux/11i/index.html#Virtual%20Partitions for information on

software version requirements.

A virtual partition can be resized automatically based on application performance using WLM. The

Sizing vPars Automatically with HP-UX Workload Manager white paper provides details on how to use

WLM to accomplish this. The white paper can be found at

http://docs.hp.com/hpux/11i/index.html#Virtual%20Partitions as well as in the information library section

of the WLM web page at http://www.hp.com/go/wlm.
