Hi, I'm working on implementing a storage plug-in for CS 4.2.
I'm looking at the following Wiki page for guidance, but have some questions: https://cwiki.apache.org/CLOUDSTACK/storage-subsystem-20.html One interface that needs to be implemented is PrimaryDataStoreDriver. I'm not sure what is expected for all of the following methods: * grantAccess: It looks like this is called in an attempt to confirm that the host which desires access to the volume in question is allowed to do so. I suspect this is where CHAP credentials might be provided? In my situation, there are a couple ways I'd like to restrict access: 1) CHAP or 2) allow a subset of IQNs to access the volume in question. Is this kind of information provided to me here? Do I simply return the IQN of the volume as a successful response from this method? What if the access sent is not sufficient? How do I deny access? * revokeAccess: I don't really understand when this method would be called or why. Perhaps I can simply implement it to return true (or false)? In my situation, when a volume is dynamically created for a hypervisor of a cluster, I'd want to allow access to it from all hosts in the app cluster in question. Maybe this method is called before the volume is deleted or something? * listObjects: I don't really understand when this method would be called or why. * createAsync: I believe this is where I place my code to create a volume (LUN) on our SAN. * deleteAsync: I believe this is where I place my code to delete a volume (LUN) on our SAN. Thanks for any guidance here! -- *Mike Tutkowski* *Senior CloudStack Developer, SolidFire Inc.* e: mike.tutkow...@solidfire.com o: 303.746.7302 Advancing the way the world uses the cloud<http://solidfire.com/solution/overview/?video=play> *™*
