Yes, I Tried NSCR.

But when deleting, I ever get "NOT FOUND".

I have a cluster but it´s components (DATA and INDEX) are lost.
When I user IDCAMS "DELETE CLUSTER.NAME CLUSTER" it says "DATA SET NOT FOUND".
When I user IDCAMS "DEFINE CLUSTER CLUSTER.NAME ..... " it says "DATA SET ALREADY EXISTS".
I need to delete it in order to create again.
How can I do it?
