    摘要: A method for identifying the cause of degraded I/O performance between a host system and a storage controller includes initially monitoring I/O performance between the host system and the storage controller. The method further detects degraded I/O performance between the host system and the storage controller using any suitable technique. Once degraded I/O performance is detected, the method determines the cause of the degraded I/O performance by analyzing historical configuration records in the storage controller. These historical configuration records enable the storage controller to correlate the degraded I/O performance with configuration changes in the storage controller and/or the connected host systems. The method then notifies one or more host systems of the cause of the degraded I/O performance. A corresponding apparatus and computer program product are also disclosed herein.
