Warning: Snapshot copies on source volume "CIFS_SVM:CIFS_Volume1" generated by SnapMirror for the purpose of mirroring to destination volume
"CIFS_SVMT:CIFS_Volume1_dst" will be deleted. Once these Snapshot copies are deleted, it will likely not be possible to re-establish a mirroring
relationship between these two volumes.
