Hi, Yeah, CHAP is not supported in the CloudStack API when creating/editing Primary Storage (in other words, you can't create an iSCSI-based Primary Storage using CHAP). To make it work for XenServer, for example, you need to set up your Storage Repository in XenServer first, then go to CloudStack and create a PreSetup-type Primary Storage.
The reason I want to create a storage plug-in for CS is because of my particular use case. The SAN my company builds supports guaranteed IOPS to iSCSI targets. What this means is we'd like to have a single VM or data disk use a single one of our iSCSI targets so we can say that VM or data disk is guaranteed a set number of IOPS. The way CS works today is generally to have multiple VMs and data disks share a single iSCSI target. In that model, we can't guarantee IOPS to any VM or data disk specifically (only to the volume as a whole). Edison's storage framework for CS 4.2 should fix this issue. When a VM is spawned or a data disk created, the storage framework should make use of the plug-in to dynamically create an iSCSI target and use it for the VM or data disk in question only. Talk to you later!
