HP Global Workload Manager 7.0 User Guide

NOTE: You must be logged in as root on the systems where you run the gwlmagent command
mentioned below.
1. Configure your CMS as indicated in the HP Matrix Operating Environment Software Installation
and Update Guide, if you have not already done so.
2. On each managed node, start the gWLM agent (if it is not already running):
# /opt/gwlm/bin/gwlmagent
Alternatively, you can start the agents through System Insight Manager, as discussed in the
HP Matrix Operating Environment Software Installation and Update 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 18).
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
