Getting Started with gWLM

gWLM is accessed through SIM.

After performing the necessary gWLM daemon configuration as described in the VSE Management Software Installation and Update Guide, the quickest way to start using gWLM to manage new systems is to use the Manage Systems and Workloads wizard, as described in the following text.

Before you start the wizard though, decide:

Which systems you want to manage with gWLM
Whether you want to manage your workloads by migrating CPU resources among npars, vpars, virtual machines, processor sets, or fss groups. (CPU migration among npars is simulated using the HP Instant Capacity product, as explained in the section “The gWLM Management Model”.)

Tabs and Menus

The controls shown in the following figure appear at the top of the Global Workload Manager screen.

Using the Wizard

To start the wizard:




	NOTE: You must be logged in as root on the systems where you run the `mxstart`, `gwlmcmsd`, and `gwlmagent` commands mentioned below. In SIM, you must be logged in as root or have authorizations for “All Tools,” “VSE All Tools,” or “gWLM All Tools.”

Configure your CMS as indicated in the VSE Management Software Installation and Update Guide if you have not already done so
On each managed node, start the gWLM agent if it is not already running:
# /opt/gwlm/bin/gwlmagent
Alternatively, you can start the agent through SIM, as discussed in the VSE Management Software Installation and Update Guide.
Connect to SIM by pointing your web browser to:
http://hostname:280
where hostname represents the hostname of the CMS.
Select:
Tools
-> VSE Management
and then click the Shared Resource Domain tab and then from the VSE Management menu bar select:
Create
-> Shared Resource Domain

The wizard guides you through the following steps:

Specifying the hosts on which to run workloads that you want gWLM to manage as part of one SRD
Setting SRD properties
Properties include the SRD name, mode, state, use of Temporary Instant Capacity, and resource allocation interval.
Specifying workload and policy settings
Settings include the workload name and policy.
Reviewing and confirming the SRD
Verify the SRD is configured as expected and select the [Finish] button to have gWLM manage the resource allocation for the workloads in the SRD.
