Re: Send Reject PDU when orignal to-be-rejected PDU is notavailable

The original PDU header has to be sent back so that the initiator
knows what was rejected.  iSCSI has a number of mechanisms that
can be used by the target to control resource consumption and
those should be used to ensure that adequate resources are
available to deal with the PDU that is to be rejected.
 
Thanks,

	Dears,
	

		I am curently implement iscsi target on a resource-limted device. In my implementation, orignal to-be-rejected PDU is not available when it realised that a Reject should be sent to initiator.
		 
		But as RFC3720 said, Target must send back the orignal PDU as the Reject's payload. 
		 
		So my question is: Why we need to send back the orignal PDU ? Can we simply eliminate it?
		 
		Thanks!
		

	Best Regards,

	Jason
