First Claim
1. A method for implementing LUN based hard zoning in a fibre channel network, comprising:
- comparing a LUN field in a Fibre Channel SCSI command frame with a list of LUNS that are allowed for a particular frame source; and
forwarding the frame if the LUN is allowed for the frame source.

Abstract
A method and system for implementing LUN based hard zoning in a fibre channel network is provided. A LUN field in a Fibre Channel SCSI command frame is compared with a list of LUNS that are allowed for a particular frame source; and the frame is forwarded if the LUN is allowed for the frame source. The comparison is performed by a port receiving the frame by using an address look up table (“ALUT”). Hard zoning is based on various frame fields and/or ALUT control codes. Also provided is a method for processing a reply to a SCSI REPORT LUN command from an initiator. The method includes, intercepting a reply to a REPORT LUN command; editing the reply to remove unauthorized LUNs; and sending the edited reply to the initiator.
