Abstract
According to one exemplary embodiment, a method for VIOS failover in an environment with a physical storage adapter is provided. The method may include assigning the physical storage adapter to a first VIOS, wherein the physical storage adapter has I/O connectivity to at least one storage device. The method may include configuring a first I/O path between the first VIOS and a second VIOS. The method may include configuring a second I/O path from a client partition to the first VIOS, wherein the second I/O path is set as a primary I/O path. The method may include configuring a third I/O path from the client partition to the second VIOS. The method may include determining the first VIOS is inaccessible. The method may include unassigning the physical storage adapter from the first VIOS. The method may include assigning the physical storage adapter to the second VIOS.
