摘要： Disclosed is a computer implemented method and apparatus for queuing I/O requests to a pending queue. The I/O device driver sets a maximum ordered queue length for an I/O device driver coupled to a storage device then receives an I/O request from an application. The I/O device driver determines whether the pending queue is sorted and responds to a determination that the pending queue is sorted, determining if queued I/O requests exceed the maximum ordered queue length. Responding to a determination that the pending queue exceeds the maximum ordered queue length, the I/O device driver adds the I/O request based on a high pointer, and points the high pointer to the I/O request.

摘要： A system and method for migrating a client partition between computer electronic complexes (CECs) while maintaining access to a Storage Area Network. An active and inactive world wide port name are generated for a client virtual channel adapter. A query is sent to a name server from the VIOS on the source CEC. The name server creates a list of small computer system interface (SCSI) targets that are available. The list is used by the VIOS on the destination CEC to verify whether any physical ports in the destination CEC have access to the same SCSI target. The client partition may be migrated between a source CEC and a destination CEC and the access to the Storage Area Network access may be maintained.

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： A method of processing manganese ore by adding the ore to an aqueous solution of acid and H.sub.2 O.sub.2 to form a leach pulp. The leach pulp is agitated for a predetermined time period at predetermined temperatures. The leach pulp is then separated into a solid fraction and a liquid fraction containing solubilized metals. The solubilized metals are then recovered from the liquid fraction.

摘要： A method, system and computer-usable medium are disclosed for managing storage system resources in a storage area network (SAN). A target data storage server registers itself within a storage area network (SAN) fabric to receive a Registered State Change Notification (RSCN) should a SCSI initiator become inactive. A SCSI initiator then requests reservation of a target LUN. In response, the target data server reserves the LUN for use by the SCSI initiator. If a RSCN is received by the target data storage server, then a GID_PN server request, which comprises the unique identifier of SCSI initiator, is generated after a predetermined time interval and a SAN fabric name server. If the name server's response to the GID_PN server request is positive, then the SCSI initiator was detected as being active and the target data storage server keeps the reservation for the LUN active for the SCSI initiator. Otherwise, the reservation for the LUN is released for use by other SCSI initiators.

摘要翻译： 公开了一种用于管理存储区域网络（SAN）中的存储系统资源的方法，系统和计算机可用介质。 目标数据存储服务器将自身注册到存储区域网络（SAN）结构中，以在SCSI启动器变为不活动状态时接收注册状态更改通知（RSCN）。 然后，SCSI启动器请求预定目标LUN。 作为响应，目标数据服务器保留LUN供SCSI启动器使用。 如果目标数据存储服务器接收到RSCN，则在预定时间间隔之后生成包含SCSI启动器的唯一标识符的GID_PN服务器请求，以及SAN结构名称服务器。 如果名称服务器对GID_PN服务器请求的响应为正，则检测到SCSI启动器处于活动状态，并且目标数据存储服务器保持SCSI启动器的LUN活动预留。 否则，LUN的预留将被释放供其他SCSI启动器使用。
