Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

Enter the cache size to store writes when the snapshot exists. The size of the
cache must be large enough to store the expected number of changed blocks
during the fire drill. However, the cache is configured to grow automatically
if it fills up. Enter disks on which to create the cache.
Press the Enter key when prompted.

The wizard starts running commands to create the fire drill setup.
Press the Enter key when prompted.
The wizard creates the application group with its associated resources. It also
creates a fire drill group with resources for the application (Oracle, for
example), the CFSMount, and the RVGSnapshot types.
The application resources in both service groups define the same application,
the same database in this example. The wizard sets the FireDrill attribute for
the application resource to 1 to prevent the agent from reporting a
concurrency violation when the actual application instance and the fire drill
service group are online at the same time.
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.
