摘要:
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.

Remotely administering a server, the server including non-volatile memory upon which is disposed one or more digital images representing the server, the server also including one or more components each of which includes non-volatile memory in which is disposed one or more digital images representing the component, where the server is connected for data communications to a management module, and remotely administering the server includes: retrieving, by the management module from the server, the digital images representing the server and the digital images representing the installed components; generating, by the management module with the digital images representing the server and the digital images representing the installed components, a graphical representation of the server with the installed components; and presenting, by the management module to a user through a GUI, the graphical representation of the server with the installed components.

A method and circuit for implementing an enhanced availability personality card for a chassis computer system, and a design structure on which the subject circuit resides are provided. The personality card includes a first erasable programmable read only memory (EPROM) and a second EPROM, each EPROM storing Vital Product Data (VPD) and a first temperature sensor and a second temperature sensor sensing temperature. A primary bidirectional bus and a redundant bidirectional bus are respectively connected between the first EPROM and the first temperature sensor and the second EPROM and the second temperature sensor, and a pair of chassis management modules. Each chassis management module includes a switch connected to both the primary bidirectional bus and the redundant bidirectional bus providing redundant paths, enabling continued function with failure of any critical personality card component.

Autoconfiguration of an IPv6 component in a segmented network including receiving an IPv6 packet; determining whether the received IPv6 packet is a router advertisement or a router solicitation; if the received IPv6 packet is a router advertisement, then retrieving through an out-of-band link a MAC address for the IPv6 component, removing a MAC address of a sending router, inserting in the packet instead an internal MAC address for forwarding packets to the IPv6 component, removing a multicast destination MAC address, inserting in the packet the destination MAC address of the IPv6 component, and forwarding the packet to the IPv6 component as a unicast message; if the received IPv6 packet is a router solicitation, then removing the MAC address of the sending IPv6 component, inserting in the packet instead an external MAC address for forwarding packets to the router, and forwarding the packet to the router as a multicast message.

摘要:
Methods and arrangements for activating Internet Protocol (IP) configurations are discussed. Embodiments include transformations, code, state machines or other logic for activating in an end node an IP configuration suitable for IP communications between the end node and another end node upon the detection of a direct IP connection of the end node to another end node. In some embodiments, the other end node may have a direct IP connect only to the end node. In some embodiments, the suitable IP configuration may involve a static IP address which has been published. In some embodiments, detecting a direct IP connection with another node may be accomplished by detecting a crossed-over Ethernet connection. In some embodiments, an operating system device driver may activate the suitable IP configuration. In other embodiments, an embedded system may activate the suitable IP configuration.

Identifying an operating system running on a computer system. In one aspect of the invention, an enumeration pattern is collected, the enumeration pattern describing an enumeration of a device that has been performed between the device and the operating system running on a host computer system. The type of the operating system running on the host computer system is identified based on the collected enumeration pattern.
摘要:
A mechanism for changing ownership over the physical power to a blade server in a blade center chassis that prevents a malfunctioning blade from jeopardizing other components in the chassis. When the management module is not present, control over power to the blade is switched to a service processor on the blade. This arbitration of control over power to a blade is accomplished by implementing a watchdog timer mechanism. The management module is responsible for tickling the watchdog timer when the present in the chassis and operating normally. This mechanism provides the management module with control over power. If the management module malfunctions or is removed, control over power is switched to the local service processor on the blade server as soon as the watchdog timer is not tickled.
