Hi @CLOUDMINER
If you delete the volume on source then volume on destination will not be deleted. You have to delete it manually.
First you have to follow the below process.
Dest> snapmirror quiesce <destination volumename>
Dest> snapmirror break <destination volumename>
Source> snapmirror destinations
source> snapmirror release <source volume name>
delete schedule entry on snapmirror config file
rdfile /etc/snapmirror.conf
take the output of the above command and paste it in note pad edit it and paste it back to snapmirror config file
wrfile /etc/snapmirror.conf
snapmirror is deleted now. You can delete source and destination volumes if you want.
