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： 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.

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： 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 GPS device is used in conjunction with a device, such as a SAN device, to record and track the device's location. A device can periodically report its location to one or more computer systems that track device locations. Another device can send a request to other devices requesting the devices' geographic location. The devices, in turn, respond with data corresponding to their geographic location. In the event of a catastrophe or other event rendering devices in one area inoperable, one of the computer systems can be used to identify a location of another device that includes similar data. The GPS data corresponding to a device can also be used to identify a technician that should respond to a device maintenance or repair event.
