Abstract
A data storage system has a network adapter to receive an I/O request. A status signal is generated in response to the I/O request, the status signal indicating a failure of a storage media to which the I/O request was directed. An operating system determines, in response to the status signal, if the storage media is in a degraded mode. If the storage media is in a degraded mode, the operating system stores the I/O operation in a log for execution at a later date. If the storage media is not in a degraded mode, the operating system reassigns the I/O request to a spare storage media. The operating system places an appropriate entry of a faulty media onto a defect list that maps to a spares pool to aid reassignment of subsequent I/O requests.
