A system having input/output hot spot tracking is disclosed. The storage system includes a storage device, a host controller coupled to the storage device, and a tracking engine coupled to the host controller and the storage device. The host controller is configured to managed input/output of the storage device. The tracking engine includes a storage map cycling between active status and passive status. Input/output commands are stored in the storage map during the active status. Like input/output commands in the storage map during active status are counted and compared to a number. Counts greater than the number are reported as input/output hot spots.

Storage volumes are provided across a plurality of storage devices, where the storage volumes include at least a first storage volume and a second storage volume. A storage controller detects fault in a portion of a particular one of the plurality of storage devices, where the portion corresponds to the first storage volume. The storage controller identifies the particular storage device as faulty for the first storage volume without identifying the particular storage device as faulty for the second storage volume.
