Description

This article describes about SnapMirror fails with an unrecoverable error and attempts to resync the relationship also fail. The relationship must be reinitialized. However, attempts to reinitialize the mirror to the same destination volume fails. 

Example: unrecoverable error that requires SnapMirror to be reinitialized:
cluster2::> snapmirror resync -source-path svm1:vol1 -destination-path svm2:vol2

Error: command failed: No common Snapshot copy found between svm1:vol1 and svm2:vol2.

cluster2::> snapmirror initialize -destination-path svm2:vol2

cluster2::> snapmirror show svm2:vol2

                            Source Path: svm1:vol1
                       Destination Path: svm2:vol2
                                Healthy: false
                       Unhealthy Reason: Transfer failed.
                     Last Transfer Type: initialize
                    Last Transfer Error: Destination volume "svm2:vol2" must be an empty                                             data-protection volume.
