Abstract
Abstract A method of on-line reconfiguring a data processing system for an added input/output (I/O) device. A configuration program is called and menus are presented. Based on menu selections, the program causes a device definition to be built. The built definition is used to construct a control block which is written into main storage during system operation such that the added device is available for use on a real time basis.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A method of on-line reconfiguring a data processing system for an added or redefined device, said method comprising: (a) building a definition for said device based on input to a configuration program; (b) determining a status of said devices as being new, redefined and not currently in use, or redefined and currently in use; and (c) building and storing a control block in main storage for said data processing system if said defined device is new, building a redefined control block and replacing a control block for the device in main storage if said device is redefined and not currently in use, or building a redefined control block and storing it in main storage to be substituted at a later time if said device is redefined and currently in use, all said building, storing or replacing steps being performed during the operation of said data processing system.
Claim 2
Independent Claim
147 words
A method of on-line reconfiguring a data processing system for an added or redefined device, said method comprising: (a) building a definition for said device based on input to a configuration program; (b) determining a status of said devices as being new, redefined and not currently in use, or redefined and currently in use; and (c) building and storing a control block in main storage for said data processing system if said defined device is new, building a redefined control block and replacing a control block for the device in main storage if said device is redefined and not currently in use, or building a redefined control block and storing it in main storage to be substituted at a later time if said device is redefined and currently in use, all said building, storing or replacing steps being performed during the operation of said data processing system.
Claim 3
Dependent Claim
32 words
A method according to claim 1 including writing said redefined control block behind said control block for said device being redefined if said device being redefined has a status of being used.
Claim 4
Dependent Claim
17 words
A method according to claim 2 including marking said device control block for said device being redefined.
Claim 5
Dependent Claim
31 words
A method according to claim 3 including deleting said device control block for said device being redefined when said device being redefined has a status of being no longer in use.
Claim 6
Dependent Claim
15 words
A method according to claim 4 including storing said device definition in a secondary store.
Claim 7
Dependent Claim
25 words
A method according to claim 5 including updating said secondary store to include an updated catalog of definitions of devices in use by said system.
Claim 8
Dependent Claim
32 words
A method according to claim 1 including replacing said control block for said device being redefined by writing over said control block for said device being redefined with said redefined control block.
