摘要： 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.

摘要： An FTDC interface with the host or user. The interface can include a command application programming interface (API) or a data storage Command-Line Interface (DS CLI)/Graphical User Interface (GUI). In certain embodiments, the FTDC interface allows a host or user to customize a desired FTDC on a two-tiered system. The first tier is one in which a host/user selects, from a list of conditions, which ones, upon occurrence of those conditions, they would like the controller to perform FTDC. In the second tier a second selection is made such that for each first tier item, the host/user will select the level of FTDC (collection and offloading of logs and/or the forcing and offloading of a statesave).

摘要： A storage controller receives a request to establish a point-in-time copy operation by placing a space efficient source volume in a point-in-time copy relationship with a space efficient target volume, wherein subsequent to being established the point-in-time copy operation is configurable to consistently copy the space efficient source volume to the space efficient target volume at a point in time. A determination is made as to whether any track of an extent is staging into a cache from the space efficient target volume or destaging from the cache to the space efficient target volume. In response to a determination that at least one track of the extent is staging into the cache from the space efficient target volume or destaging from the cache to the space efficient target volume, release of the extent from the space efficient target volume is avoided.
