HP-UX Workload Manager A.03.00 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 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’s partition management and PSETs

HP does not support WLM’s simultaneous management of partitions (virtual partitions or

nPartitions) and PSET-based workload groups. CPUs cannot be properly moved between

these partitions when PSETs are active.

Compatibility of utilitydc and PSETs

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

PSET-based workload groups.

Compatibility with PRM

WLM and PRM should not be used to manage the same system at the same time. Using these

products to control resources at the same time may cause inconsistent behavior and

undesirable performance.

WLM uses PRM for some types of resource management. You can bypass WLM and use PRM

directly; however, if you do use PRM directly through its own configuration file, do not use any

of the WLM interfaces.

When using WLM, you can use PRM’s informational and monitoring commands such as

prmlist and prmmonitor. You can also use the prmrun and prmmove commands, among

others. If you use the prmconfig command, invoke it with no options or the -u (unlock)

option—do not use the -r (reset) option.

Compatibility with gWLM

WLM and HP Global Workload Manager (gWLM) should not be used to manage the same

system at the same time. Using these products to control resources at the same time may

cause inconsistent behavior and undesirable performance.
