JUJU Charm Certification

[SivaRamaPrasad Ravipati]

OK. Thank you.

I have One more Question. Knowing answer for this question is very
important for us.

We have developed a JUJU Charm for configuring cinder to use one of our
Storage array as the backend.


So How to redeploy the Charm to add more storage arrays to configure cinder
without destroying/removing the current deployed charm. [For example, We
don't want to remove the current configured storage arrays from the Cinder
configuration.]

Thanks,
Siva.
