Configuring local attributes in the fire drill service group
The fire drill setup wizard does not recognize localized attribute values for
resources. If the application service group has resources with local (per-system)
attribute values, you must manually set these attributes after running the wizard.
Verifying a successful fire drill
Bring the fire drill service group online on a node that does not have the application
running. Verify that the fire drill service group comes online. This action validates
that your disaster recovery solution is configured correctly and the production
service group will fail over to the secondary site in the event of an actual failure
(disaster) at the primary site.
If the fire drill service group does not come online, review the VCS engine log to
troubleshoot the issues so that corrective action can be taken as necessary in the
production service group.
You can also view the fire drill log, located at /tmp/fd-servicegroup.pid
Remember to take the fire drill offline once its functioning has been validated.
Failing to take the fire drill offline could cause failures in your environment. For
example, if the application service group were to fail over to the node hosting the
fire drill service group, there would be resource conflicts, resulting in both service
groups faulting.
Scheduling a fire drill
You can schedule the fire drill for the service group using the fdsched script. The
fdsched script is designed to run only on the lowest numbered node that is
currently running in the cluster. The scheduler runs the command hagrp -
online firedrill_group -any at periodic intervals.
To schedule a fire drill
1
Add the file /opt/VRTSvcs/bin/fdsched to your crontab.
2
To make fire drills highly available, add the fdsched file to each node in the
cluster.
