Autonomic hardware-level storage device data integrity checking

Abstract

A system and method for autonomically monitoring data integrity during logical and physical storage and retrieval of data by a storage device. In one embodiment, the method of the present invention includes scheduling data integrity checking in accordance with an operative input/output (I/O) state of the storage device. The scheduling preferably includes first retrieving an I/O command, such as a read or write command, from a disk interface controller and determining whether or not the I/O command has been pre-marked for data checking. In response to the I/O command not being marked for prescribed data checking, a further determination is made of whether or not data integrity checking is required in association with the object I/O command as specified by scheduler rules. Responsive to determining that a data integrity check is required in association with the I/O command, the I/O command is marked as requiring an associated data integrity check.
