Configuring Packages and Their Services

Creating a Disk Monitor Configuration

Chapter 6 207

NOTE The

SERVICE_CMD

must include the string “cmresserviced” or the

cmconfigres will fail to find the disks to be monitored. cmconfigres

looks for SERVICE_CMD entries including the text “cmresserviced” to

determine which disks to monitor.

It is important to set SERVICE_RESTART to an empty string (““).

After setting up the package ASCII files and control scripts, use

cmcheckconf and cmapplyconf to apply the package configuration, as

usual. Then create a monitor configuration file using the cmconfigres

command. This can be done for all nodes in the cluster at one time, or it

can be done a node at a time. The first approach is easiest when first

setting up the cluster, but the second approach may be more appropriate

when modifying the monitoring configuration at a later time.

Configuring All Disks for Monitoring

During initial cluster setup, to create a monitoring configuration that

includes all disks for all packages that contain a monitoring service, use

the following command:

# cmconfigres create

This command builds the $SGCONF/cmresmond_config.xml file on each

node in the cluster. The command operates by examining a node at a

time and scanning all the package control scripts for the packages that

might at some time be running on that node. Note that the content of the

$SGCONF/cmresmond_config.xml files is different from node to node if

the list of packages that can run on each node is different from other

nodes.

The following is a specimen of a cmresmond_config.xml file:

<?xml version="1.0" encoding="UTF-8"?>
