This chapter discussed an emergency procedure for quickly bringing up a single node in a RAC
cluster in case of failure of all voting disks or OCR devices. The same procedure may be applied
to other severe error scenarios that prevent Oracle Clusterware from functioning. The proce-
dure modifies the configuration of Oracle Clusterware, ASM, and RDBMS instances. It is not
destructive—the changes made may be reversed quickly, as soon as the underlying problem
that caused the outage of Oracle Clusterware has been resolved.
