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 partition management and PSETs

WLM now supports simultaneous management of partitions (virtual partitions or nPartitions)

and PSET-based workload groups. Such support requires the following:

• If Instant Capacity is available on the complex, it must be v7 or later

• If HP-UX Virtual Partitions (vPars) is on the complex, it must be v4 (A.04.01) or later

• If Pay Per Use is on the complex, it must be v7 or later

Compatibility of utilitydc and PSETs

HP does not support the simultaneous use of the PPUTK command utilitydc and

PSET-based workload groups.

Compatibility of psrset and PSETs

When WLM is managing PSETs, do not use the psrset command to change settings.

Compatibility with PRM

As of version A.03.01, WLM no longer includes PRM in the bundle. As a result, upgrading

WLM no longer triggers a reboot.

WLM will run only with PRM C.03.00 or later. If PRM C.03.00 or later is already on the

machine where you are installing or upgrading WLM, you can continue to manage FSS and

PSET-based workload groups just as if PRM had been installed with WLM.

If you are installing WLM for the first time on a machine, you can only use a strictly

host-based configuration—a 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. To manage FSS and PSET-based workload groups, you must install

PRM separately. With your purchase of WLM, you are entitled to a PRM license. For

information on receiving the PRM license, contact your regional licensing service

organization.

When the Servicecontrol Manager (SCM) bundle is built during the WLM installation, it will

include the PRM API only if PRM is already installed. The SCM integration bundle will not be

able to validate PRM-based configurations without the PRM API.

NOTE WLM’s configuration wizard requires PRM. If you plan to use the WLM

configuration wizard, install the appropriate version of PRM.
