Julo Chuck Micalizzi <chuck.micalizzi@qlogic.com> on 13/03/2001 19:12:59 Please respond to Chuck Micalizzi <chuck.micalizzi@qlogic.com> To: Julian Satran/Haifa/IBM@IBMIL cc: ips@ece.cmu.edu Subject: inexistent LUN Julian, Regarding version 5 of the iSCSI draft: On page 71, in Section 2.20 it states: It may happen that a target receives a message with a format error (e.g., inconsistent fields, reserved fields not 0, inexistent LUN etc.) or a digest error (e.g., invalid payload or header)... I'm concerned about the iSCSI layer having the responsibility of validating the LUN. In my opinion this is the responsibility of the SCSI layer. The target iSCSI layer should ignore the LUN field and let the SCSI layer validate the LUN. In SCSI, a command directed to a non-existent or missing LUN is not always an error. The SCSI Command Inquiry and Request Sense won't return "check condition" status if addressed to a non-existent LUN. chuck micalizzi
