HP Global Workload Manager 7.0 User Guide

NOTE: HP recommends starting these daemons at boot only when used in a secure operating

environment.

Setting GWLM_CMS_START to 0 (zero) prevents automatic use at boot of HP Matrix OE visualization

and HP Capacity Advisor.

Automatic restart of gWLM’s managed nodes in SRDs (high availability)

Whenever a managed node boots, the node’s gWLM agent attempts to automatically rejoin the

node in its SRD, providing high availability. The only configuration steps you need to perform for

this behavior to happen are:

1. Ensure the /etc/rc.config.d/gwlmCtl file on each managed node has

GWLM_AGENT_START set to 1. You can run the following command on each system where

gwlmagent is running to make this change for you:

# /opt/gwlm/bin/gwlmagent --enable_start_on_boot

In the same file, you also need GWLM_CMS_START=1 on the system where gwlmcmsd is

running. However, when you ran vseinitconfig during installation, this change was

automatically made.

2. (Optional) Edit the property

com.hp.gwlm.node.HA.minimumTimeout

in the file /etc/opt/gwlm/conf/gwlmagent.properties to set the minimum number

of seconds that must pass before a managed node considers itself separated from its SRD.

Set this property to ensure that minor network problems do not cause a managed node to

prematurely consider itself separated.

gWLM uses this value only if it is larger than 10 multiplied by gWLM’s allocation interval. For

example, with an allocation interval of 15 seconds, a node can go 2.5 minutes without

communicating with its SRD before the node’s gWLM agent attempts to re-connect with the

SRD.
