3.13 Settings for Using VCS

To use VCS, install HDLM on all of the hosts that comprise the cluster, and then

configure the HDLM devices. Also, carry out the following procedure before starting

VCS:

1. Specify the settings for starting the

preonline script when VCS starts.

When you have specified the settings for starting the

preonline script, go to

step 2.

For details on the setting method, see the VCS documentation.

The following example shows settings for starting the

preonline script when

VCS starts:

# haconf -makerw

# hagrp -modify

service-group PreOnline 1

# haconf -dump -makero

# cp -r /opt/VRTSvcs/bin/sample_triggers/preonline /opt/

VRTSvcs/bin/triggers

2. In the preonline script used when VCS starts, register the script provided by

HDLM.

Add the following code to the line under

# put your code here... in the

preonline script.

system("/usr/DynamicLinkManager/cluster/dlm_vcs_pgr_release

$ARGV[1]");

The following shows an example of editing the preonline script. The shaded

portion represents the part to be added.
