Hi --

Under mac 10.1, whether IOSCSIPeripheralDeviceNub is existence or not?

IOSCSIPeripheralDeviceNub has existed since Public Beta and 10.0.x releases. However, you might be thinking of using IOSCSILogicalUnitNub. IOSCSILogicalUnitNub did not exist in 10.1.x. You'd have to create a similar object which did similar things (basically copy wholesale the IOSCSILogicalUnitNub implementation and change the class name).

In the IOUSBMassStorageClass source code, i think registerService() is important for every lun. but how can i get lun info to this function?

You'd have to do this how IOSCSILogicalUnitNub does it. It overrides ExecuteRequest() and tags the SCSITask with the LUN information.
