HP-UX Workload Manager A.03.01 Release Notes for HP-UX 11i v1 and HP-UX 11i v2

HP-UX Workload Manager Release Notes

Compatibility information and installation requirements

Compatibility of WLM’s virtual partition management and

Instant Capacity / PPU

If you have Instant Capacity or Pay Per Use (PPU) software installed, use WLM’s virtual

partitions management only if you have vPars version A.03.01 or later.

If you have a vPars version prior to A.03.01, using WLM’s virtual partition management may

cause an Instant Capacity core to be automatically enabled without customer authorization. If

this situation occurs, please contact your HP representative.

With vPars version A.04.01 or later, use Instant Capacity v7 or later.

Compatibility of WLM’s virtual partition management and certain

CPU bindings

Do not use cell-specific CPU bindings or user-assigned CPU bindings on virtual partitions you

are going to manage with WLM.

Compatibility of WLM’s partition management and PPUTK

Do not use WLM’s partition management (virtual partition or nPartition management) and

the Pay Per Use Toolkit (PPUTK) tool utilitydc at the same time.

Compatibility of WLM with HP Integrity Virtual Machines

WLM supports HP Integrity Virtual Machines (Integrity VM). You can run WLM both on the

Integrity VM Host and in an Integrity VM (guest), but each WLM runs as an independent

instance. To run WLM on the Integrity VM Host, you must use a strictly host-based

configuration—a WLM configuration designed exclusively for moving CPUs across HP-UX

Virtual Partitions or nPartitions, or for activating Temporary Instant Capacity cores or Pay

Per Use CPUs. (WLM will not run with FSS groups or PSETs on Integrity VM Hosts where

guests are running.)

WLM runs inside an Integrity VM but will not support Pay Per Use, vPar, and Instant

Capacity integration. However, Integrity VM will take advantage of CPU resources added to

the Integrity VM Host by Pay Per Use, Instant Capacity, and Temporary Instant Capacity. In

addition, when running WLM inside an Integrity VM, you should specify a WLM interval

greater than 60 seconds. This helps ensure a fair allocation of CPU resources for FSS groups.
