Problems with an export domain

Hello,

I have problems with the nfs export domain attached to my Red Hat Enterprise Virtualization environment. I want to remove it to add a new export domain, or recreate it, but I can not do it.

When I try to destroy it appears the following message:

• Cannot destroy Storage. Storage status illegal.

What I need to do to remove it to add a new one or to recreate it?

Thanks in advance, Edgar
