Abstract
Systems, methods, and computer program products for providing operating system (O/S) redundancy in a computing system are provided. One system includes a host computing device, a plurality of memory devices, and a sub-loader coupled between the host computing device and the plurality of memory devices. Each memory device stores a respective O/S and the sub-loader is configured such that the plurality of memory devices appear transparent to the host computing device. One method includes designating, a first logical unit device as a primary logical unit device and subsequently determining that the first logical unit device is unresponsive. The designation is removed from the first logical unit device and a second logical unit device is designated as a new primary logical unit device. One computer program product includes instructions for performing the above method.
