Abstract
Abstract A logically partitioned data processing system has a policy defining responsive actions to be undertaken by a process in one partition because of a monitored failure of an operating system in another partition. When such a failure occurs, the monitoring partition, if authorized, automatically communicates with a hypervisor to initiate the responsive actions on the failing partitions to reset and/or reconfigure that failing partition. Communication of action request between the partition and the hypervisor is accomplished without operator intervention, through a Service Call Logical Processor interface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
235 words
In a logically partitioned data processing system, comprising one or more physical processors, having two or more logical partitions each capable of containing an associated control program, an apparatus for cross-partition control comprising: a) authorization means for authorizing a controlling process in a first one of the two or more logical partitions to initiate responsive actions on a second of the two or more logical partitions; b) policy definition means comprising a trigger event and an associated set of responsive action definitions, each responsive action definition in the set having an associated control program and specifying a responsive action to initiate when said trigger events occurs; c) monitor means, in the first one of the two or more logical partitions, for monitoring the status of others of the two or more logical partitions, to detect the trigger event in one of said others of the two or more logical partitions; d) hypervisor means, within said one or more physical processors, for initiating said responsive action; e) communication means for communicating a request for the responsive action from the controlling process in the first one of the two or more logical partitions, to said hypervisor means, when the monitor means has so detected said trigger event, and the authorization means has so authorized the controlling process, and the responsive action is specified by the responsive action definition having the associated control program having the trigger event.
Claim 2
Dependent Claim
75 words
The apparatus of claim 1 in which the authorization means comprises: a) security frame means for authorizing the first one of the two or more logical partitions to initiate responsive actions on the second of the two or more logical partitions; b) cross-partition enablement means in the control program in said one of said others of the two or more logical partitions, for authorizing said controlling process to initiate responsive actions against that control program.
Claim 3
Dependent Claim
17 words
The apparatus of claim 2 in which the trigger event comprises a failure in the control program.
Claim 4
Dependent Claim
28 words
The apparatus of claim 3 in which the set of responsive action definitions comprises a cross-partition deactivate action, a cross-partition system reset action, and a non-specific deactivate action.
Claim 5
Dependent Claim
19 words
The apparatus of claim 4 in which the set of responsive action definitions further comprises a resource reconfiguration action.
Claim 6
Dependent Claim
21 words
The apparatus of claim 5 in which the communication means comprises a Service Call Logical Processor function having an SCCB interface.
Claim 7
Dependent Claim
233 words
In a logically partitioned data processing system, comprising one or more physical processors, having two or more logical partitions each capable of containing an associated control program, a method for cross-partition control comprising the steps of: a) authorizing a controlling process in a first one of the two or more logical partitions to initiate responsive actions on a second of the two or more logical partitions; b) initializing a policy comprising a trigger event and an associated set of responsive action definitions, each responsive action definition in the set having an associated control program and specifying a responsive action to initiate when said trigger events occurs; c) causing the first one of the two or more logical partitions to monitor the status of others of the two or more logical partitions, to detect the trigger event in one of said others of the two or more logical partitions; d) initiating said responsive action by a hypervisor within said one or more physical processors; e) communicating a request for the responsive action from the controlling process in the first one of the two or more logical partitions, to said hypervisor, when the first one of the two or more logical processors has so detected said trigger event, and the controlling process has been authorized, and the responsive action is specified by the responsive action definition having the associated control program having the trigger event.
Claim 8
Dependent Claim
78 words
The method of claim 7 in which the step of authorizing comprises: a) authorizing the first one of the two or more logical partitions to initiate responsive actions on the second of the two or more logical partitions by a security frame means; b) authorizing said controlling process by a cross-partition enablement means in the control program in said one of said others of the two or more logical partitions, to initiate responsive actions against that control program.
Claim 9
Dependent Claim
17 words
The method of claim 8 in which the trigger event comprises a failure in the control program.
Claim 10
Dependent Claim
28 words
The method of claim 9 in which the set of responsive action definitions comprises a cross-partition deactivate action, a cross-partition system reset action, and a non-specific deactivate action.
Claim 11
Dependent Claim
19 words
The method of claim 10 in which the set of responsive action definitions further comprises a resource reconfiguration action.
Claim 12
Dependent Claim
24 words
The method of claim 11 in which the step of communicating is performed by a Service Call Logical Processor function having an SCCB interface.
