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
