Zusammenfassung:When moving workload partitions (WPARs) from machine to machine, operating systems may encounter errors that prevent successful WPAR migration. Recording and reporting errors can be challenging. To move WPARs, the operating system may employ a plurality of software components, such as code residing in user space (e.g., application programs, OS libraries, and shell scripts), code residing in the operating system's kernel, and code residing on remote machines. Embodiments of the invention include a framework that enables all the software components to record errors. The framework can also report the errors to users and processes.
