Abstract
An interface node selects a logical block address that corresponds to a contiguous memory location located on a storage device that is accessible by multiple interface nodes. The interface node retrieves a logical block address status indicator from a shared memory area and determines, based upon the logical block status indicator, whether the logical block address is utilized by a different interface node. If the logical block address is not utilized by a different interface node, the interface node tests the corresponding contiguous memory location.
