James, On the Windows host they allow hot add/remove of block devices attached to the scsi controller(s) assigned to the guest. So, when a hot add/remove event occurs, the host sends a message to the guest that something has changed on the hba and the guest is responsible for figuring out what has changed: a) Setup state to manage new devices that may have been added and b) get rid of devices that may have been removed. As I look at implementing this functionality for Linux guests, I would need to be able to do a scan on the hba under question and deal only with whatever has changed. Is this something that the scsi core supports or would I need to roll out a version of scan that would ignore devices already scanned (except for the remove case) and properly add new devices that may be found. Any guidance here would be greatly appreciated. Regards, K.
