    摘要： A computer-implemented method, apparatus, and computer-usable program code is provided to generate unique identifiers for a logically partitioned and/or virtualized data processing system. A number of computing entities supported by the data processing system are identified to form a number of identified entities. A set of unique identifiers is generated based upon the number of identified entities. A unique identifier from the set of unique identifiers is assigned to a logical computing entity during operation of the data processing system.

    摘要： The present invention relates to a method, a computer program product and a system for managing virtual instances of a physical port attached to a network. The method is based on the Fibre Channel N_Port virtualisation for a physical Fibre Channel N_Port. Multiple virtual Fibre Channel adapters share a single physical N_Port among multiple operating system instances. The invention discloses means for the automatic and persistent generation and administration of unique Worldwide Port Names needed for the N_Port virtualisation.

    摘要： An I/O adapter sharing mechanism in a logically partitioned computer system allows sharing a network I/O adapter between logical partitions in an efficient manner. A first logical partition owns (or controls) the I/O adapter, and a second logical partition desires to use (or share) the I/O adapter. An I/O adapter device driver that includes a hardware interface is provided in the first logical partition. A virtual device driver is provided in the second logical partition that provides a set of functions that is at least partially defined by querying the I/O adapter device driver in the first logical partition. The I/O adapter sharing mechanism includes a transfer mechanism that allows data to be transferred directly from the virtual device driver in the second logical partition to the I/O adapter without passing through the I/O adapter device driver in the first logical partition.

    摘要： Maintaining SAN access rights during migration of operating systems including assigning, to a virtual SAN interface adapter of a source virtualization intermediary (SVI′) on the source server, at least two world wide port names (WWPN), identifying devices coupled for data communications to the SVI through the primary WWPN; selecting a target physical SAN interface adapter on a target server available to a target virtualization intermediary (‘TVI’) having a target virtual SAN interface adapter; assigning to the target virtual SAN interface adapter the secondary WWPN; identifying devices coupled for data communications to the TVI through the secondary WWPN; determining whether the devices coupled to the SVI through the primary WWPN are also coupled to TVI through the secondary WWPN; migrating the operating system from the source server to the target server if the devices coupled to the SVI through the primary WWPN are also coupled to TVI through the secondary WWPN.

    摘要： An enhanced fibre channel adapter with multiple queues for use by different server processors or partitions. For a non-partitioned server, the OS owns the adapter, controls the adapter queues, and updates the queue table(s). An OS operator can obtain information from the fibre channel network about the fibre channel storage data zones available to the physical fibre channel adapter port and can specify that one or more zones can be accessed by a specific processor or group of processors. The processor or group of processors is given an adapter queue to access the zone or zones of storage data. This queue is given a new World Wide Port Name or new N-Port ID Virtualization identifier, to differentiate this queue from another queue that might have access to a different storage data zone or zones. For a partitioned server, one partition owns the adapter, controls the adapter queues, and updates the queue table(s). The partition management tool can obtain information from the fibre channel network about the fibre channel storage data zones available. A system operator can assign one or more storage zones under a fibre channel storage adapter to a partition. Each partition that has access to a zone or zones under an adapter is given an adapter queue to access the zone or zones. This queue is given a new World Wide Port Name or new N-Port ID Virtualization identifier, to differentiate this queue from another queue that might have access to a different storage data zone or zones.

    摘要： At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/O firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions.
