Abstract
In accordance with certain techniques, at a first processor of a dual-processor storage system, a change in an initial logical unit corresponding to a storage area in a physical storage device of the storage system is detected. Based on the change in the initial logical unit, a plurality of update operations to be performed on a mapped logical unit driver mapping a plurality of initial logical units including the initial logical unit to a plurality of mapped logical units are determined. An indication of the plurality of update operations is sent to a second processor of the storage system, to cause the second processor to perform the plurality of update operations on a peer mapped logical unit driver associated with the mapped logical unit driver.
