Resuming mirror and vault relationships
If you have a quiesced mirror and vault relationship, you can resume the relationship by using System Manager. When you resume the relationship, normal data transfer to the destination volume is resumed and all the protection activities are restarted.
If you have quiesced a broken mirror and vault relationship from the command-line interface (CLI), you cannot resume the relationship from System Manager. You must use the CLI to resume the relationship.
Click Protection > Volume Relationships.
Select the mirror and vault relationship that you want to resume, and then click Operations > Resume.
Select the confirmation check box, and then click Resume.
Normal data transfers are resumed. If there is a scheduled transfer for the relationship, the transfer is started from the next schedule.
