Migrating from disk-based to server-based fencing in an online cluster
You can migrate between disk-based fencing and server-based fencing without
incurring application downtime in the SF Oracle RAC clusters.
You can migrate from disk-based fencing to server-based fencing in the following
cases:
■ You want to leverage the benefits of server-based fencing.
■ You want to replace faulty coordinator disks with CP servers.
Similarly, you can migrate from server-based fencing to disk-based fencing when
you want to perform maintenance tasks on the CP server systems.
See “Migrating from server-based to disk-based fencing in an online cluster”
on page 63.
