摘要
In a Virtual Input/Output (I/O) Server (VIOS) partition within a data processing system that comprises cluster-aware VIOSes, a method includes: performing, via a backup/restore utility of a cluster aware (CA) operating system (OS) executing on a processor resource of the first VIOS partition, a backup operation on the first VIOS partition, which creates a first configuration backup file having configuration information about the hardware, logical and virtual devices of the VIOS partition; storing the configuration backup file within local storage; and responsive to receipt of a VIOS restore command: retrieving the configuration backup file from the local storage; and restoring the configuration of the hardware, logical and virtual devices of the first VIOS to a state that existed at a time at which the backup operation creating the configuration backup file was performed.
