To abort the takeover,
                                                you can giveback the
                                                aggregates that were relocated
                                                as part of the attempted
                                                takeover using the "storage
                                                failover giveback -ofnode
                                                Node01" command.  If
                                                you want to continue the
                                                takeover, address the failures
                                                and then use the "storage
                                                failover takeover -ofnode
                                                Node01" command.  If
                                                you want to continue with the
                                                takeover without addressing
                                                the failures you can do so by
                                                using the "storage failover
                                                takeover -ofnode
                                                -bypass-optimization true"
                                                command.  Warning: Setting the
                                                parameter to true will result
                                                in a longer overall client

                                                events on a cluster system.
