How is it possible to signal SCSI mid-layer (or other layers) of a presence of a newly hot-plugged disk ? 2.. Can an adapter's device driver trigger SCSI subsystem to scan channels for new LUNs / Targets ? 3.. Is this can be handled in a kernel level ? is there a user space application that can be triggered to start scanning adapters (obviously through SCSI subsystem) and registering new LUNs / Targets etc... ? 4.. How does SCSI API allow insertion of a new disk ? 5.. Is there a generic way of hot-plugging disks ? Thank you alot, Rabeeh
