摘要:
An apparatus, system, and method are disclosed for receiving digital instructions at devices or controllers sharing an identity. A first controller receives a digital instruction instance over a communications medium. The digital instruction instance maybe a firmware instance. The first controller has ownership of the communications medium and shares the communications medium and a common identity with a second controller. An ownership module transfers ownership of the communications medium from the first controller to the second controller. The ownership module may transfer ownership in response to the first controller successfully receiving the digital instruction instance. A request module requests a retransmission of the digital instruction instance, and may request the retransmission in response to the transfer of ownership of the communications medium. The second controller receives the retransmitted digital instruction instance in response to the retransmission request.

An apparatus, system, and method are disclosed for updating firmware to a plurality of memory devices residing on disparate controllers wherein each controller includes an identical communication path address. A management module writes a firmware image to a memory device residing on a primary controller. The primary controller, in turn, copies the firmware image to another memory device residing on a secondary controller. In this manner, the apparatus, system, and method may update firmware on a plurality of memory devices. Because the primary controller is tasked with updating the secondary controller, the management module is only aware that the firmware of the primary controller has been updated. In this manner, updating of the firmware on the secondary controller is transparent to the management module.

An apparatus, system, and method are disclosed for accessing redundant data. A verification value module calculates a first verification value for a first redundant memory. In addition, the verification value module calculates a second verification value for a second redundant memory. In one embodiment, a validation module validates the first and second verification values. A selection module accesses the first redundant memory if the first verification value is equivalent to the second verification value. In a certain embodiment, the selection module identifies and accesses the redundant memory with a most advanced generation count if the first and second verification values are valid and are not equivalent.

In accordance with the present invention, there is provided a multi-port bridge where problems in conventional virtual bridging are solved, and especially a multi-port bridge which can be managed with a program that manages only two-port bridges. The multi-port bridge comprises, in terms of hardware, one adapter such a TRN adapter 70 connected to one port 50, other adapters such as other ISDN adapters 71 to 77 connected to a plurality of other ports 51 to 57, and processor 86 for providing virtual bridges and a virtual Token-Ring between one adapter and other adapters. Processor 86 provides by means of a program a virtual bridge module 120 having a bridging function to TRN adapter 70 connected to one port 50, and virtual bridge modules 121 to 127 having a bridging function to other ISDN adapters 71 to 77 connected to ports 51 to 57, respectively. Further, processor 86 provides by means of the program virtual Token-Ring module 128 for coupling these virtual bridge modules 121 to 127.
摘要:
Methods, computer systems, and computer program products are provided for managing a storage network system is provided. The storage network system includes a plurality of zones. Each of the plurality of zones includes at least one storage network device. A link-down event associated with one of the storage network devices is detected. One of the plurality of zones is identified is identified as being unused if the zone is not accessed by another of the storage network devices in another of the plurality of zones and if the zone does not access another of the storage network devices in another of the plurality of zones.

A SAS expander forms a first path coupling the SAS initiator and a first port of a SAS target together. The first SAS expander notifies the SAS initiator of a virtual expander address instead of a SAS address of the first SAS expander. The first SAS expander notifies the SAS initiator of a virtual target port address, at least instead of a SAS address of the first port of the SAS target. A second SAS expander forms a second path coupling the SAS initiator and a second port of the SAS target together. The second SAS expander notifies the SAS initiator of the virtual expander address instead of a SAS address of the second SAS expander. The second SAS expander notifies the SAS initiator of the virtual target port address, at least instead of a SAS address of the second port of the SAS target.

摘要:
Provided are a method, system, and computer storage device for managing zone information for devices in a network. A zone table includes entries indicating whether devices in at least one zone are permitted to communicate. An attributes table has attributes of the devices indicated in the zone table. A determination is made of attributes from the attributes table for devices indicated in the zone table entries as being permitted to communicate. The entries in the zone table indicating that devices can communicate are verified by determining whether the attributes for the devices indicated as permitted to communicate in the entries in the zone table are consistent with the determined devices being able to communicate. Information is outputted indicating whether the entries in the zone table indicating that devices can communicate are in error.
