Claim 1
Independent Claim
272 words
A configuration control system for changing the system configuration of a data processing system (GCMP) having at least one global storage unit, (GSU0, GSU1), a plurality of clusters (CLEA-CLED), each of the clusters (CLEA-CLED) having a channel processing unit (CHP), at least one central processing unit (CPU), at least one main storage unit (MSU), a memory control unit (MCU) and a service processor (SVP), the at least one global storage unit (GSU0,GSU1) being connected in common to the plurality of clusters, and a first configuration control means (CFR) for holding connection information for each unit in each cluster; characterised in that the system also includes: a second configuration control means (GCFR) for holding configuration control information of the at least one global storage unit (GSU0, GSU1) and the plurality of clusters (CLEA-CLED) which is independently controlled from the first configuration control means (CFR); means for generating a specific order for writing/reading the configuration control information to the second configuration control means (GCFR); and, means for setting a corresponding bit of the second configuration control means (GCFR) to a connection state when a bus between the at least one global storage unit (GSU0, GSU1) and the plurality of clusters (CLEA-CLED) is set to the connection state by the first configuration control means (CFR); wherein the connection configuration between the at least one global storage unit (GSU0, GSU1) and the plurality of clusters (CLEA-CLED) designated by the first configuration control means (CFR) is automatically set to the second configuration control means (GCFR), and the second configuration control means (GCFR) is controlled independently of the first configuration control means (CFR) based on the specific order.

A configuration control system for changing the system configuration of a data processing system (GCMP) having at least one global storage unit, (GSU0, GSU1), a plurality of clusters (CLEA-CLED), each of the clusters (CLEA-CLED) having a channel processing unit (CHP), at least one central processing unit (CPU), at least one main storage unit (MSU), a memory control unit (MCU) and a service processor (SVP), the at least one global storage unit (GSU0,GSU1) being connected in common to the plurality of clusters, and a first configuration control means (CFR) for holding connection information for each unit in each cluster; characterised in that the system also includes: a second configuration control means (GCFR) for holding configuration control information of the at least one global storage unit (GSU0, GSU1) and the plurality of clusters (CLEA-CLED) which is independently controlled from the first configuration control means (CFR); means for generating a specific order for writing/reading the configuration control information to the second configuration control means (GCFR); and, means for setting a corresponding bit of the second configuration control means (GCFR) to a connection state when a bus between the at least one global storage unit (GSU0, GSU1) and the plurality of clusters (CLEA-CLED) is set to the connection state by the first configuration control means (CFR); wherein the connection configuration between the at least one global storage unit (GSU0, GSU1) and the plurality of clusters (CLEA-CLED) designated by the first configuration control means (CFR) is automatically set to the second configuration control means (GCFR), and the second configuration control means (GCFR) is controlled independently of the first configuration control means (CFR) based on the specific order.
Claim 3
Dependent Claim
24 words
A configuration control system as claimed in claim 1, wherein each of the first (CFR) and second (GCFR) configuration control means is a register.
Claim 4
Dependent Claim
30 words
A configuration control system as claimed in claim 1 or 2, wherein the second configuration control means (GCFR) is provided in the at least one global storage unit (GSU0, GSU1).
