Carefully consider the report of what failback would do BEFORE you include the -y option and launch the operation. During the failback process, end-user clients cannot issue commands against the server. |
| -v | Specifies the verificationTime as a number of seconds prior to the launch of the failback command. The default value of 300 seconds means that any file content that was updated from 1 - 300 seconds prior to launch of failback will be verified. This is to ensure that this file content will be correct when the failback process completes on the new master server. The failback command proceeds as soon as it has determined that the new master server has received correct file content. The legal range is between 0 (no verification) and 43200 seconds (12 hours). |

To cancel the failback during the quiesceWait period, press Ctrl-C |
