Abstract
Error handling is simplified for a self-virtualizing IO resource that utilizes a physical function adjunct partition for a physical function in the self-virtualizing IO resource to coordinate error recovery for the self-virtualizing IO resource, by restarting each virtual function adjunct partition associated with that physical function to avoid the need to coordinate error recovery within the logical partitions to which such virtual function adjunct partitions are assigned.
