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

Introduction
Supported Environments
Chapter 1 25
In a vPars environment, if the LPMC (Low Priority Machine Check)
monitor of the Support Tools deactivates a processor, it does not
automatically replace the failing processor with an iCOD processor.
The processor replacement must be performed manually using the
icod_modify command. For more information, see the manual titled
Instant Capacity on Demand (iCOD) User’s Guide for version B.05.00
at http://docs.hp.com.
CAUTION
CPU Expert Tool is not supported on vPars servers. Using the CPU
Expert Tool on vPars servers will give unpredictable results. For
complete information on using the Support Tools with vPars, see the
Support Tools document:

• iCOD (Instant Capacity on Demand) and PPU (Pay Per Use)
iCOD allows online activation of iCOD CPUs; PPU allows
purchasing CPU time of processors.
Beginning with vPars version A.02.01 and iCOD version B.05.00,
iCOD is now supported in a vPars environment; PPU is not yet
supported.
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.
To determine your current version of iCOD, PPU, or vPars, use the
command swlist.
Please see the note “WLM (Workload Manager)” on page 26 when
using WLM, iCOD, and vPars.
Please see the note “Support Tools” on page 24 for information on
iCOD and LPMC_monitor.
For more information on iCOD, see the manual titled Instant
Capacity on Demand (iCOD) User’s Guide for version B.05.00 at
http://docs.hp.com. Also see “Installing and Removing vPars-related
Bundles” on page 81.
