A system, and computer usable program product for addressing a workload partition are provided in the illustrative embodiments. A packet of data directed to the WPAR and including a combined address is received at a software stack. A determination is made whether the combined address includes an identifier that is reserved. If the identifier is not reserved, the identifier is used to identify the WPAR in the data processing system and the packet is sent to the WPAR. The software stack is an application configured to enable data communication using a protocol of the packet, and is modified to detect, recognize, and process the combined address for routing the packet to the WPAR. The combined address may be logically formed using an identifier associated with the data processing system and an identifier associated with the WPAR, which may be located in different portions of the packet.

A method and system for providing multiple input/output paths for accessing storage devices includes providing two or more logical paths between a virtual I/O client partition and a storage device and establishing a physical path between the virtual I/O client partition and the storage device by assigning the storage device to a first logical path of the two or more logical paths. The method further includes reestablishing the physical path by dynamically assigning the storage device to a second logical path of the two or more logical paths in an event of unavailability of the first logical path.
