HP Insight Global Workload Manager 6.3
User Guide
Abstract
This document presents an overview of the techniques and tools available for using HP Insight Global Workload Manager
software for Integrity servers (or gWLM). It exposes you to the essentials and allows you to quickly get started with gWLM. This
document is intended to be used by Virtual Server Environment (VSE) system administrators, VSE application administrators,
and other technical professionals involved with data center operations, administration, and planning. An understanding of
HP-UX system administration concepts and procedures is assumed.

- Error during discovery of compartments
- Modifying Java while gWLM is running
- Missing or unexpected historical data (system clocks differ)
- Sample missing at start or end of gwlmreport output
- Workload with fixed policy gets more resources than requested
- Only one SRD is allowed to be deployed
- SRD deployment times out and displays a blank screen
- Application hangs in fss group
- Scripts not placed in correct workloads
- Processes moved to default pset or default fss group
- Sizes/allocations less than policy minimums for Virtual Machines
- Starting management of monitored workloads with pset compartments
- Unable to remove workload from nested partitions SRD
