Abstract: Methods and structure for masking of logical unit numbers (LUNs) within a switching device coupled with one or more storage enclosures. Each storage enclosure defines one or more logical volumes each identified by a LUN within the storage enclosures. The switching device gathers LUN definition information regarding each LUN defined by each storage enclosure coupled with the switching device. LUN access permission information may be provided by an administrative node/user defining a level of access permitted or denied for each host system for each LUN for each storage enclosure. The switching device then intercepts a REPORT LUNS command from any host directed to a storage enclosure and responds with only those LUNs to which the requesting host system has permitted access. Further, any other SCSI command intercepted at the switching device directed to a LUN to which the host system does not have access is modified to identify an invalid LUN.
