cannot remove clone db

i create two clone of db, but when i dont need them i cannot delete\unmount clone over snapcenter so i unmount clone and delete on netapp manually.

but now i still see clone under primary backups, also under snapvault is the snapshoot showing on snapcenter.

getclonejob is schowing my job

 should i check netapp and if i found it on system delete it over cli?

but how should i remove things frommsnapcenter?

i see i must contact netap that they said me what to delete in snapcenter db. 

or can someone who have allready this problem said me the solution?
