A system and method for thresholding system power loss notifications in a data processing system are provided. Power loss detection modules are provided in a data processing system having one or more data processing devices, such as blades in an IBM BladeCenter® chassis. The power loss detection modules detect the type of infrastructure of the data processing system, a position of a corresponding data processing device within the data processing system, and a capability of the data processing system to provide power during a power loss scenario. The detection module detects various inputs identifying these types of data processing system and power system characteristics and provides logic for defining a set of behaviors during a power loss scenario, e.g., behaviors for sending system notifications of imminent power loss. The detection of the various inputs and the defining of a set of behaviors may be performed statically and/or dynamically.

A method for maintaining vital product data (VPD) contained in an EEPROM (Electrically Erasable Programmable Read-Only Memory) on a field replaceable unit (FRU) of a computer system that has a cache. The method includes maintaining a copy of the VPD in the cache, retrieving the copy of the VPD from the cache upon receiving a read request of the VPD, and, upon receiving a write request to write data to the VPD, writing the data to the copy of the VPD, determining whether the VPD in the EEPROM is in synchronization with the copy of the VPD in the cache, and, if the VPD and the copy of the VPD are in synchronization, writing the data to the EEPROM.

An apparatus, system, and method are disclosed for backing up vital product data for a data processing device. A communication module establishes a communications channel with a maintenance module of a service center. The service center remotely supports the data processing device. A backup module copies vital product data to the maintenance module and the maintenance module maintains the vital product data copy. In one embodiment, a restore module receives a command to restore the vital product data copy. The communication module establishes the communications channel between the restore module and the maintenance module and the maintenance module copies the vital product data copy to the restore module.

A system and method are directed towards a pseudo multi-master operation on a serial bus. The pseudo multi-master operation allows multiple devices without standard multi-master functionality to operate on the serial bus as masters. In a disclosed example, the serial bus is an Inter-Integrated Circuit (I2C) bus, which is isolated when an adapter card requires access to the I2C bus, such as to update vital product data (VPD) to a memory device, and to cache the updated VPD to a chassis management module.

Because cable length affects signal quality, amplifying signals differently to account for cable length (“tuning”) becomes especially important when high speed signals are used. Cable length information may be stored in a non-volatile memory which may be integrated into a cable assembly or may be a discrete component between the cable and an interface. Rather than using a dedicated data line to the memory component a ground line may be connected to the memory component and multiplexed. During normal operation the selected line is grounded through a switching device. When a cable is detected, a management controller changes the state of the switching device to decouple the selected line from ground to allow the management controller access to the data stored in the memory component, including cable length information. The selected line is then re-coupled to ground and interface circuits may be tuned for the cable length.

A method, system, and computer program product for dynamically updating vital product data (VPD) based on the presence of an installed feature card supported by an input/output (I/O) adapter in a data processing device. A VPD utility initiates the boot up process of the I/O adapter with the aid of the common boot code in the Boot/VPD segment of a flash module. The hardware configuration registers are loaded with default values. Additionally, the VPD from the (flash) Boot/VPD segment is loaded. When the feature card is present, the VPD utility retrieves configuration information for the feature card and loads the hardware configuration registers with values relevant to the feature card. The VPD utility retrieves the feature card VPD and loads available VPD updates into the (flash) alternate Open Boot segment. The flash firmware image uses the VPD to manage the adapter.

A method of virtually removing field replaceable units (FRUs) from a computer system during concurrent maintenance operations. Firmware within a flexible service processor (FSP) assigns unique resource identification (RID) numbers to each FRU in the computer system. The firmware collects vital product data (VPD) for each FRU and generates a duplicate test shared library, which is stored in a memory directory corresponding to the FSP. When the firmware receives input from a graphical user interface (GUI) that includes at least a first FRU selected for virtual removal from the computer system, the firmware adds the RID number of the selected FRU to the memory directory and recollects VPD. The FSP subsequently ignores any FRUs corresponding to RID numbers stored in the memory directory during operation of the computer system.

A computer processor subsystem, e.g. called a “target”, in response to receiving an update to vital product data of the system from a source computer processor subsystem, examines the update to detect the vital product data of the target computer processor subsystem stored by the source computer processor subsystem; and, in response to the detected vital product data being incorrect, the target computer processor subsystem forwards its correct vital product data to the source computer processor subsystem having the incorrect vital product data. A computer processor subsystem is the authoritative reference for its vital product data.

A method of powering on a plurality of devices includes identifying a plurality of power distribution units (PDUs) disposed in a rack, wherein each PDU receives power from a main power source and includes a circuit breaker. A plurality of devices disposed in the rack are identified, wherein each device receives power from one of the PDUs, and wherein the plurality of devices are server nodes, network switches or external data storage devices. Vital product data (VPD) is obtained from a service processor in each device, wherein the VPD identifies the device by a model identification code. For each PDU, the plurality of devices connected to the PDU are powered on in a sequence to prevent an inrush current from tripping the circuit breaker within the PDU, wherein the sequence powers on devices in order of ascending commonality of the model identification code.
