Just you need to break the replication relationship and delete the DR group. Please find the following,

Deleting copy sets
----------------------
To delete copy sets using Command View EVA:
1. Click the Active folder for the source Vdisk of the copy set.
2. Click the Data Replication tab.
3. Click Remove member.
4. Click OK in the confirmation window.
5. Click Keep remote Vdisk, Delete remote Vdisk, or Cancel as appropriate.
Deleting DR groups
---------------------
To delete DR groups:
1. Click the Data Replication folder.
2. Select the DR group to be deleted.
3. Click Delete.
4. Click OK.

Both the source and destinations Vdisks will be kept but they will no longer have a
replicating relationship.

You can use vdisks as normal.

Yes. Unpresent the affected destination virtual disk members. One at a time, select the affected virtual disks and select the Presentation tab on the Vdisk Properties window; then select Unpresent.

Also please note that if the DR group is a member of a managed set then you need to delete the DR groups from the managed set as well and finally remove the managed set.

Always unpresent the destination vdisk. No need to touch source vdisk.

Then go for the deletion of DR group.

Deleting a DR group removes the relationship between the virtual disk members; it does not delete data from the virtual disks.

thee solution was to unpresent the destination and delete the dr groups without touching the source
