snapmirror show or OnCommand System Manager reports a SnapMirror Relationship Status of "Preparing" for a significant amount of time.

ClusterA::> snapmirror show Progress Source Destination Mirror Relationship Total Last Path Type Path State Status Progress Healthy Updated ----------- ---- ------------ ------- -------------- --------- ------- -------- svmSource:volSource XDP svmDest:volDest Snapmirrored Preparing 98.17GB true 01/01 12:00:00

The Preparing operation may run longer and appear to transfer more data than a typical update operation.
In some cases, scheduled updates will be missed causing the relationship to report unhealthy with the error: Scheduled update was delayed because another SnapMirror operation for the relationship is in progress
