Abstract:
A system including a small computer system interface comprising:a plurality of host processors;a controller connected to each of said plurality of host processors, said controller including an interconnection of only one SCSI initiator, at least one host adapter, a microprocessor and a memory;a plurality of SCSI targets with each of said plurality of SCSI targets connected to said controller;said each of said host processors having issuing and receiving means for issuing separate commands to designated SCSI targets through said controller and for receiving information in response to said commands from said designated SCSI targets through said controller;said controller further having first processing means for processing said separate commands from each of said host processors to said designated members of said SCSI targets, and second processing means for processing said information from said designated members of said SCSI targets to said each of said plurality of host processors;each of said designated members of said SCSI targets having generating means for generating said information in response to said commands, said information signifying if a UNIT ATTENTION condition exists; andsaid controller further having first storage means for storing said information as ATTENTION DATA from each of said plurality of SCSI targets for each of said plurality of host processors, when said UNIT ATTENTION condition exists, said first storage means further having a separate memory location for each combination of said SCSI targets and said host processors.
