Abstract
A service processor has a memory, and a controller coupled to the memory. The controller is configured to perform part of a maintenance procedure on a data storage system such that a state of the data storage system transitions from a first state to a second state, and store, in a memory, a data structure identifying the second state. The controller is further configured to, after the maintenance procedure is aborted prior to completion of the maintenance procedure and after a transition of the state of the data storage system from the second state to a third state, (i) restore the data storage system to the second state based on the data structure stored in the memory, and (ii) complete the maintenance procedure.
