[ovirt-devel] GetDeviceList and direct LUNs

Hi, I want to implement a feature that would allow one to manually refresh sizes for direct LUNs and I am not sure if existing code in the engine codebase is gonna help with that. RefreshLunsSizeCommand seems to be doing what is needed, but it operates on a premise that LUNs to refresh belong to a storage domain which makes most of its code irrelevant for purposes of direct LUNs. It seems that workhorse is GetDeviceList command, but from the code I can't quite understand if it's supposed to be used with external iSCSI targets. Especially 'VDS' part here confuses me since I am not sure what VDS we're talking about in the first place when using direct LUN. If GetDeviceList is of no use, is there anything else VDSM provides? Thanks, Fedor Gavrilov
