Abstract:
1. A method for accessing a plurality of input/output (I/O) devices physically distributed across a plurality of logical partitions (LPARs) without a single point of failure comprising: creating a distributed virtual input/out (VIO) server by running a VIO tool on each LPAR of the plurality of LPARs; wherein each LPAR is operable to access the plurality of I/O devices using inter-partition communication and each LPAR is operable to access an I/O device to which it is directly connected; wherein each LPAR is mapped to a dedicated I/O device that is not shared with the plurality of LPARs; wherein each VIO tool performs steps comprising: wherein a plurality of input/output (I/O) devices physically distributed across a plurality of logical partitions (LPARs) are accessible without a single point of failure.
