How to delete a zone in database

[Amir Abbasi]

Hi All,

 

All accounts, Domains and then hosts, clusters, pods, Primary Storage have
been removed but secondary storage could not be removed and I face the
following error:

 

Cannot delete image store with active templates backup!

 

I can see old templates of deleted accounts. How can I delete them off from
cloud database and then remove old zone?

 

Thanks in advance
