description Hibernation and remote restore functions of a client logical partition (LPAR) that exists within a data processing system having cluster-aware Virtual Input/Output (I/O) Servers (VIOSes) is performed via receipt of commands via a virtual control panel (VCP) through an underlying hypervisor. The client hibernation data file is stored in a shared repository by a source/original VIOS assigned to the client. The hypervisor receives a remote restart command and assigns a target/remote client LPAR and a target VIOS. The source I/O adapters and target I/O adapters are locked and the target VIOS gathers adapter configuration information from the source VIOS and configures the target adapters to be able to perform the I/O functionality provided by the source adapters to the client LPAR. The target VIOS then retrieves the client's hibernation data file, and the client LPAR is restored at the remote LPAR with the target VIOS providing the client's I/O functionality.
