摘要： A method for testing a computer bus using a bridge chip having a freeze-on-error option that enables a computer system's central processing unit (CPU) to recover and continue processing even when the computer bus is not functional. The testing method of the present invention remains transparent to a user and can be accomplished while performing standard diagnostics tests. In general, the present invention injects an input/output (I/O) error into a specific bus slot of the computer bus to test the functionality (such as the error recovery capability) of the bus. The present invention then recovers from the failure condition without having the computer system shutdown or stop working and without having to restart the computer system. More specifically, the method for testing a computer bus according to the present invention includes enabling the freeze-on-error option on the bridge chip, injecting an error into the specified computer bus slot and recovering from the injected error. The error recover capability of the computer bus is determined by examining the status of the bus slots both with the injected error condition and without the injected error condition.
摘要翻译：一种使用具有冻结错误选项的桥接芯片测试计算机总线的方法，其使计算机系统的中央处理单元（CPU）即使在计算机总线不起作用时也能恢复并继续处理。本发明的测试方法对用户保持透明，并且可以在执行标准诊断测试时完成。通常，本发明将输入/输出（I / O）错误注入到计算机总线的特定总线槽中，以测试总线的功能（例如错误恢复能力）。然后，本发明从故障状态恢复，而不需要计算机系统关闭或停止工作，而不必重启计算机系统。更具体地说，根据本发明的用于测试计算机总线的方法包括启用桥芯片上的冻结错误选项，将错误注入到指定的计算机总线插槽中并从注入的错误中恢复。计算机总线的错误恢复能力是通过检查总线插槽的状态，通过注入的错误条件和没有注入的错误条件来确定的。

摘要： A system and method for managing a Fibre Channel adapter is disclosed. When a close request is received by the Fibre Channel adapter, the adapter is set to a quasi-open state. In a quasi-open state, the adapter keeps the link to the Fibre Channel network open, releases extended resources, and maintains minimal resources in order to keep the link open. When a request is received by the adapter while in a quasi-open state, the request is rejected thereby preventing other devices from logging into the quasi-opened device and informing other devices that the quasi-opened device is not currently communicating across the Fibre Channel network. An information handling system and a computer program product for implementing the Fibre Channel adapter quasi-open state are further disclosed.

摘要： A system and method for remotely waking up a Fibre Channel attached device. A Fibre Channel attached device is set in a quasi-open mode wherein the device summarily rejects most requests and allocates a minimal set of resources to operate the adapter. One request that is not rejected is an activation request received from another Fibre Channel attached device. When an activation request is received, an optional authentication process can be invoked to insure that only authenticated devices issue the activation command. An additional security feature can be used to restrict the devices authorized to activate a device. A list of devices can be stored on nonvolatile storage or in memory. When a requesting device has been authenticated, its address is checked against the list of approved devices before the device adapter is activated.

摘要： Disclosed is a computer implemented method, data processing system and computer program product to discover an SCSI target. The method comprises a client adapter transmitting an N_port ID virtualization (NPIV) login to a virtual I/O server (VIOS). The client adapter receives a successful login acknowledgement from the VIOS and issues a discover-targets command to the fabric. Upon determining that the SCSI target information is received, wherein the SCSI target information includes at least one SCSI identifier. Responsive a determination that SCSI target information is received the client adapter issues a port login to a target port, wherein the target port is associated with the at least one SCSI target. The client adapter makes a process login to form an initiator/target nexus between a client and at least one SCSI target. The client adapter queries the SCSI target by using a world wide port name associated with the target port.

摘要： A method for intelligent patch scheduling for a virtual (I/O) server is provided. Virtual I/O performance indicators of a virtual I/O server are monitored. The performance indicators are stored in a database. Historic averages of the performance indicators are maintained in the database. Patches to be applied to a client partition of the virtual I/O server are received. A reboot window is received for the client partition and is an allowed time frame for rebooting to apply the patches. Future virtual I/O utilization is predicted by running predictive modeling utilizing the historic averages of the performance indicators, and based on the predictive modeling, a specific time within the allowed time frame is determined for rebooting the client partition of the virtual I/O server to apply the patches. The virtual I/O server is rebooted to apply the patches to the client partition at the specific time within the reboot window.

摘要： Disclosed is a computer implemented method, apparatus, and computer program product for regulating received data in a multiple operating system environment on an I/O adapter. The method includes a hypervisor for determining that the I/O adapter indicated a receive completion. The hypervisor, responsive to retrieving the receive completion, determines that the receive completion is associated with a successful status. The hypervisor, determines in hypervisor space whether an at least one data packet satisfies a security criterion. The hypervisor, routes the data packet to at least one selected from a group consisting of an operating system partition of the multiple operating system environment and a network address on a local area network.

摘要： Embodiments that dynamically manage physical and virtual multipath I/O are contemplated. Various embodiments comprise one or more computing devices, such as one or more servers, having at least two HBAs. At least one of the HBAs may be associated with a virtual I/O server that employs the HBA to transfer data between a plurality of virtual clients and one or more storage devices of a storage area network. The embodiments may monitor the availability of the HBAs, such as monitoring the HBAs for a failure of the HBA or a device coupled to the HBA. Upon detecting the unavailability of one of the HBAs, the embodiments may switch, dynamically, from the I/O path associated with the unavailable HBA to the alternate HBA.
