Abstract
A method, apparatus, and system of exclusive access during a critical sub-operation to enable simultaneous operations are disclosed. In one embodiment, a method of a host device includes identifying a critical sub-operation of an operation associated with a storage system, applying a lock associated with the critical sub-operation based on a type of the sub-operation, providing exclusive access of the critical sub-operation to a first instance requiring the critical sub-operation, denying other instances access to the critical sub-operation during an interval comprising a period when the first instance executes the critical sub-operation, and releasing the lock when the critical sub-operation is no longer required by the first instance. The first instance and the other instances may originate on different host devices.
