One aspect includes an electronic device that includes a component configured to generate diagnostic information indicative of a fault occurring in the electronic device. The electronic device also includes a persistent display coupled to the component and configured to display the diagnostic information.

Robust fault diagnosis for electronic devices

A method for recovering data in a redundant array of independent disks (RAID) is disclosed. In one embodiment, such a method includes implementing a RAID in a storage architecture comprising a RAID controller and a storage enclosure containing a set of storage drives belonging to the RAID. The RAID controller is configured to detect a failure condition associated with at least one of the storage drives in the set. In response to detecting the failure condition, the RAID controller sends, to the storage enclosure, an instruction to copy data from a first storage drive in the set to a second storage drive in the set as part of a RAID rebuild process. The storage enclosure receives the instruction and executes it without substantially involving the RAID controller in the copy process. A corresponding system and computer program product are also disclosed.

Enclosure-encapsulated RAID rebuild

A method for use in a computerized storage system comprising one or more replaceable units, for managing testing of one or more replacement units, where the storage system is automatically placed in a testing mode in response to a given unit being replaced and if testing fails the storage system automatically fails back to a service mode.

Computerized storage system comprising replaceable units for managing testing of replacement units

A method, apparatus and software is disclosed, for use in a computerised storage system comprising one or more replaceable units, for managing testing of one or more replacement units, where the storage system is automatically placed in a testing mode in response to a given unit being replaced and if testing fails the storage system automatically fails back to a service mode.
