HP Global Workload Manager 7.3 and 7.3 Update 1 User Guide

Changing from advisory mode to managed mode
Advisory mode allows you to see what CPU resource requests gWLM would make for a
workload—without actually affecting resource allocation. (Advisory mode is not available for SRDs
containing virtual machines, psets, or fss groups due to the nature of these compartments.) Managed
mode, however, allows gWLM to automatically adjust the resource allocations for your defined
workloads.
To change from one mode to the other:
NOTE: In System Insight Manager, you must be logged in as root or have authorizations for
“All Tools” or “Matrix OE All tools.”
NOTE: If you are changing from managed mode to advisory mode and you do not plan to
change back soon, be aware that gWLM leaves the npar and vpar and pset compartments with
the number of cores they had in the last allocation interval. Set the compartments to your desired
sizes before changing to advisory mode by associating fixed policies with all the compartments
and waiting for an allocation interval to pass.
1. Ensure System Insight Manager, the gWLM CMS daemon or service (gwlmcmsd) and all the
gWLM agents (gwlmagent) are still running, as explained in the section “Setting up gWLM
(initial setup steps)” (page 21).
2. Connect to System Insight Manager by pointing your web browser to:
http://hostname:280
where hostname represents the hostname of the CMS.
3. From the System Insight Manager menu bar, select:
Tools→HP Matrix OE visualization...
and then click the Shared Resource Domain tab.
4. Select the SRD for which to change the mode.
5. From the HP Matrix OE visualization menu bar, select:
Modify→Shared Resource Domain
6. Change to the desired mode.
7. Click OK.
Quick Link Options
In the previous procedure, instead of selecting an SRD and using the HP Matrix OE visualization
menu bar, you can find the Details table for the SRD and then choose one of the following options:
• Click the Change SRD to advisory mode link
• Click the Modify SRD link
Creating a new policy
A policy instructs gWLM how to manage a workload’s resources. You can create a policy when
managing a workload or create a policy separately. To create a policy separately:
NOTE: In System Insight Manager, you must be logged in as root or have authorizations for
“All Tools” or “Matrix OE All tools.”
1. Ensure in System Insight Manager, the gWLM CMS daemon or service (gwlmcmsd) and all
the gWLM agents (gwlmagent) are still running, as explained in the section “Setting up
gWLM (initial setup steps)” (page 21).
2. Connect to System Insight Manager by pointing your web browser to:
http://hostname:280
