Abstract:
1. In a cluster aware data processing system having a plurality of cluster aware Virtual Input/Output (I/O) Servers (VIOSes), at least one client logical partition (LPAR) and a hypervisor providing an interface between the plurality of cluster aware VIOSes and a virtual control panel (VCP), a method comprising: receiving, at a source VIOS of the plurality of cluster aware VIOSes, a hibernation request for a client LPAR; the source VIOS determining a storage device within a distributed storage repository for storing a generated hibernation data file of the client LPAR; the source VIOS securely writing the hibernation data file from the client LPAR to the determined storage device within the distributed storage repository, wherein the hibernation data file includes a configuration information of one or more source I/O adapters assigned to the client LPAR by the source VIOS; and initializing, via the VCP, a remote restart of the client LPAR at a target LPAR managed by a target VIOS of the plurality of cluster aware VIOSes using the hibernation data file stored within the storage device, wherein the remote restart comprises: wherein the target VIOS has security access to resources of the hibernating client LPAR.
