Starting to see these messages with more requency, just wanted to make sure they're not something to be concerned about... but given that SnapDrive is preventing the deletion to ensure the SM relationship is preserved strikes me as a GOOD thing.


Am I correct in this assumption or?







It looks like the SMO created snapshot that's trying to be deleted is newer than the snapmirror snapshot which is needed by snapmirror. Check your snapmirror scheduled time and the snapshot retention in SMO.


Am still having thesame issue here ...any head way.
