A method and apparatus for implementing power up detection in a power down cycle to dynamically determine whether a failed component in a system prevents another Initial Program Load (IPL) or re-IPL, or result in a loss of resources. Predefined mandatory functions are called to collect power down/up data that prevents re-IPL, or results in the reduction of resources. A user is notified, allowing the customer to continually utilize the system, while ordering hardware to be replaced.

Implementing power up detection in power down cycle to dynamically identify failed system component resulting in loss of resources preventing IPL

In an approach for chemical detection for a water source, a processor receives, from a network device of a plurality of network devices, data, wherein the data includes at least one of image data, video data, chemical sensor data, and biosensor data. A processor updates a predictive model with the data. A processor receives a table of possible chemical compositions from the predictive model. A processor determines to send an alert based on the table of possible chemical compositions. A processor sends the alert to a user device.

Chemical detection system for water source

A method, computer program product, and computer system to maintain high availability of a service processor. An embodiment provides program code with a location of a second service processor (the second service processor is communicatively coupled to the first service processor). The program code stops a virtual machine during runtime, including instruction execution and IO operations, where during runtime, the virtual machine executes one or more processes to service and manage computing resources in the distributed computing environment. The program code generates a micro-checkpoint of the virtual machine. The program code resumes the instruction execution of the virtual machine and transmits the micro-checkpoint to a second service processor based on the location and then resumes IO operations. The second service processor utilizes the micro-checkpoint to enable a hypervisor on the second service processor to start a virtual machine on the second service processor.

Microcheckpointing with service processor

An error mechanism provides stored error information to assist in determining the cause of failure of a storage device such as a hard disk drive. The error mechanism gathers information surrounding an error event from various software and hardware components in the system. An event command is sent to the storage device that includes the gathered information. The storage device stores the gathered information from the event command in a log on the storage device. After the storage device is removed from the system the error information in the log can be used to determine the cause of the failure. The event command may be standardized into an existing industry communication protocol or be vendor specific.

Reporting errors to a data storage device

A method is disclosed, as well as a related system and computer program product, for use with a plurality of networked computing devices comprising a plurality of physical ports. The method comprises determining that a non-volatile memory (NVM) device is removably connected with a first port owned by a first virtual machine associated with a first owning entity, and determining whether the NVM device was previously connected with a second port owned by a second virtual machine associated with a second owning entity. The method further comprises determining whether the NVM device has a predefined association with a first instruction file that specifies one or more restrictions for accessing data stored in the NVM device. The method further comprises providing, to the first virtual machine, access to the data stored in the NVM device in accordance with the one or more restrictions.

An optimizer controller controls a hypervisor optimizer to regulate operation of the optimizer to insure the optimizer does not negatively impact operation of software applications. The optimizer controller monitors applications and application performance to determine whether to turn on or off specific optimization features for specific applications. The optimizer may also notify a user of potential problems. The optimizer controller may utilize optimization rules for specific applications that set the conditions for controlling the optimizer. The rules may be dynamically changed based on observed performance and trends of the applications.

Embodiments include method, systems and computer program products for redundantly storing product data for an electronic component on an external device. Aspects include determining that product data stored in a primary storage device is corrupted and determining whether the product data is available on the external device that is in communication with the electronic component. Based on a determination that the product data stored in the primary storage device is corrupted and that the product data is available on the external device, aspects include obtaining product data from the external device to continue operation of the electronic component.

Electronic component having redundant product data stored externally

Aspects of the disclosure generally relate to cables and back shells having integrated force gauges. The force gauge includes a sliding member that engages features such as grooves formed in one or more surfaces of the back shell. The grooves and/or sliding member are sized and shaped such that a different forces applied to the sliding member facilitates movement between respective grooves.

Integrated force gauge cable mechanism

For a chassis having a port mounted on a side of the chassis and connected to electronics in the chassis, with a plug mated in the port and a cable connected to the plug, first and second supports are mounted on the chassis side on opposing sides of the port, where each support has a respective, predetermined length extending away from the chassis side. A strap defines a slot beginning at a first end of the strap and extending along a portion of the strap's length. The strap is placed with the cable inserted in the slot and the plug at a central portion of the strap. With the supports mounted on the chassis side on opposing sides of the port, the strap connected to the respective supports, at least the plug forces curvature in a central portion of the strap, so that the central portion of the strap clamps the plug.

Technology for maintaining secure connections of electronic cabling

An aspect includes detecting a recurring intermittent error in a path of a network in a system that includes at least one data transmission port configured for connection to at least one shared data storage device via a plurality of paths of the network. It is determined by a path control module (PCM) in the network, whether a path recovery action has been initiated by a fiber channel protocol driver in the network. In response to determining that the path recovery action has not been initiated, the data transmission port is prevented from accessing the path for a specified time period by moving the path into a degraded sub-state, and subsequent to the specified time period the data transmission port is provided access to the path. In response to determining that the path recovery action has been initiated, the data transmission port is provided access to the path.

Multipath driver cognitive coordination

Embodiments provided in this disclosure include a method, computer program product, and system for protecting sensitive data in a processing system comprising a plurality of processor cores. The method includes designating at least one processor core for processing sensitive data, and during a dump event, capturing data from each of the plurality of processor cores except the designated processor core to prevent unauthorized access to sensitive data.

Enhanced traceability of cables is provided using illumination. An embodiment comprises introducing a chemiluminescent (alternatively, flourescent) solution into a chamber coupled to at least a portion of an insulating jacket that surrounds a transmission medium, the chamber being initially hollow and, in at least a portion thereof, comprised of a substance through which light is viewable, such that upon introduction of the solution through a port, light emitted by the solution is viewable through at least a portion of the chamber. In another embodiment, a first and second compartment contain a first and second substance, respectively, and are physically separated. When an opening is caused in the physical separation, the substances are allowed to mix, the substances being chosen as providing a chemiluminescent reaction upon the mixing, such that light emitted by the chemiluminescent reaction is viewable.
