Application No. 08/219,554
comprising separate addresses for ATTENTION DATA
from each of said plurality of SCSI targets for each
of said plurality of host processors on a one to one
basis so that ATTENTION DATA from one of said
plurality of SCSI targets for one
of said host processors can be cleared without
clearing any other ATTENTION DATA, with said method
comprising the steps of:
receiving at said controller a command from one of
said plurality of host processors for one of said
plurality of SCSI targets;
determining if said controller contains ATTENTION
DATA from said one of said plurality of SCSI
targets;
determining if said command is a request for
ATTENTION DATA upon indication that said controller
contains ATTENTION DATA from said one of said
plurality of SCSI targets; and
returning ATTENTION DATA from said controller to
said one of said plurality of host processors for
said one of said plurality of SCSI targets and
clearing at said controller only the ATTENTION DATA
for said one of said plurality of host processors
from said one of said plurality of SCSI targets when
said command is a request for ATTENTION DATA.
