Abstract
A method, apparatus, and computer implemented instructions for saving data in a logically partitioned data processing system. An error is detected in the logically partitioned data processing system. Data needed for error analysis of the error is saved in a power independent memory associated with a service processor.
Claims27
A method for saving data in a logically partitioned data processing system, said system including a plurality of processors that are assigned to one of a plurality of logical partitions, the method comprising:
- detecting an error in the logically partitioned data processing system;
- and
- saving data needed for error analysis of the error in a power independent memory that is included within a service processor, said service processor being utilized to manage said plurality of logical partitions.
A logically partitioned data processing system comprising:
- a bus system;
- a communications unit connected to the bus system, wherein data is sent and received using the communications unit;
- a firmware connected to the bus system, wherein a set of instructions are located in the firmware;
- a plurality of processors that are assigned to one of a plurality of logical partitions:
- a service processor connected to the bus system, said service processor being utilized to manage said plurality of logical partition;
- a power independent memory included within the service processor;
- and
- a host processor connected to the bus system, wherein the host processor executes the set of instructions in firmware to detect an error in the logically partitioned data processing system;
- and save data needed for error analysis of the error in the power independent memory included within the service processor.
A data processing system for saving data in a logically partitioned data processing system, said system including a plurality of processors that are assigned to one of a plurality of logical partitions, the data processing system comprising:
- detecting means for detecting an error in the logically partitioned data processing system;
- and
- saving means for saving data needed for error analysis of the error in a power independent memory included within a service processor, said service processor being utilized to manage said plurality of logical partitions.
A computer program product in a computer readable medium for saving data in a logically partitioned data processing system, said system including a plurality of processors that are assigned to one of a plurality of logical partitions, the computer program product comprising:
- first instructions for detecting an error in the logically partitioned data processing system;
- and
- second instructions for saving data needed for error analysis of the error in a power independent memory included within a service processor, said service processor being utilized to managed said plurality of logical partitions.
