Resuming mirror relationships
You can resume a quiesced mirror relationship. When you resume the relationship, normal data transfer to the mirror destination is resumed and all the mirror activities are restarted.
If you have quiesced a broken mirror 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 relationship that you want to resume.
Click Operations > Resume.
Select the confirmation check box and click Resume.
Data transfer to the mirror destination resumes for the selected mirror relationship.
