Aspects of the invention include receiving system data associated with a first system, the first system comprising a plurality of system components, wherein the system data comprises component data for each system component in the plurality of system components, obtaining historical performance data for each system component in the plurality of system components, determining at least one testing constraint associated with the first system, determining a test environment for the first system, the test environment comprising a plurality of test cases for the first system based on the system data, the historical performance data, and the at least one testing constraint, and executing the test environment on the first system.

Dynamic testing of systems

An aspect includes receiving a drive log page including data from a plurality of disk devices, in which the drive log page includes a plurality of attribute fields including a reassignment field that tracks data movement from a failing sector of a disk device to a new sector of the disk device. Performing, by the system, a failure prediction based on attribute data of the drive log page to identify one or more disk devices of the plurality of disk devices that are predicted to fail. Disabling, by the system, the one or more disk devices in response to the failure prediction.

Analytics initiated predictive failure and smart log

A system determines that a given drive in an array is due for replacement. The system ranks available replacement drives based on their predicted rates of failure. The system replaces the given drive with a replacement drive that has the lowest predicted rate of failure.

Storage array drive recovery

A method, computer program product, and a system where a processor(s) obtains data comprising trends recognized by an observer of the system over time; data comprised of more than one vintage. The processor(s) transforms the data measurable dimensions and assigns the transformed data to vintages and to distinct periods of time. The processor(s) generates an image from the transformed data that represents the trends, organized by the distinct periods of times and the vintages.

Automated trend detection by self-learning models through image generation and recognition

A method and computer program product for sending a data request from a host bus adapter logic processor to a hard disk drive, setting a standard time out period for receiving a reply from the hard disk drive, sensing vibration in the hard disk drive, sending a vibration alert signal from the hard disk drive to the host bus adapter logic processor in response to the sensed vibration exceeding a predetermined amount of vibration, and, in response to receiving the vibration alert signal from the hard disk drive, the host bus adapter logic processor establishing an extended time out period for receiving the reply. The rotational vibration sensor used by the hard disk drive for repositioning the read/write head may also be used to sense the vibration and form the basis for the vibration alert signal, such as a vibration error code. By extending the time out period during high vibration events, the hard disk drive can ride out the event without being tagged as having failed. Accordingly, the hard disk drive can then be available for use following the high vibration event.

Hard disk drive availability following transient vibration

A system start-up routine is implemented to determine system device power requirements and system power capabilities, determine a maximal number of devices which can be started at one time, and start the maximal number of devices. The devices are, for example, direct access storage devices, i.e., disk drives.
