    摘要: The number of domain identifiers is incrementally increased for use by a switch in an established fiber channel switched fabric. In other words, the number of domains assigned to a switch by the Principal Switch of the fiber channel switched fabric is increased without triggering the reconfiguration of the established fiber channel switched fabric. In one implementation, incrementally adding one or more additional domain identifiers includes requesting said one or more additional domain identifiers from a Principal Switch of the fiber channel switched fabric using a different World Wide Name (WWN) than used to acquire the original one or more domain identifiers used by the switch.

    摘要: A Fiber Channel switch is provided for a relative addressing scheme for domain values to avoid losing portions of a Fiber Channel identifier. At a Fiber Channel switch, data is stored that assigns a relative domain field value to a run-time domain. The relative domain field value used for a Fiber Channel identifier is determined for devices connected to the switch based on the run-time domain of the devices and the virtual storage area network in which the devices are active. A Fiber Channel identifier is stored in a memory of the switch that comprises the relative domain field value determined for the device together with area and port values for the device. The relative domain value is either a reserved domain field value for an existing virtual storage area network or any of the regular domain field values for a new virtual storage area network.

    摘要: Methods and apparatus for reconfiguring a fabric associated with a storage area network (SAN) are disclosed. According to one aspect of the present invention, a method includes undergoing an update process, the update process being arranged to update software associated with a switch. The switch is included in a SAN fabric. The method also includes determining when the update process is completed, and ascertaining whether there is at least one state change associated with the SAN fabric when the update process is completed. Finally, the method includes initiating a recovery action in the SAN fabric if there is at least one state change associated with the SAN fabric.

    摘要: A Fibre Channel switch and related methods are provided for a relative addressing scheme for domain values used by the switch to avoid losing other portions of a Fibre Channel identifier if a particular run-time domain becomes invalid. At a Fibre Channel switch, data is stored that assigns a relative domain field value to a run-time domain in one of a plurality of virtual storage area networks. The relative domain field value used for a Fibre Channel identifier is determined for each of a plurality of devices connected to the Fibre Channel switch based on the run-time domain of the respective devices and the virtual storage area network in which the respective devices are active. A Fibre Channel identifier is stored in a memory of the Fibre Channel switch for each of the plurality of devices. The Fibre Channel identifier comprises the relative domain field value determined for the device together with area and port values for the device. The relative domain value is either a reserved domain field value for an existing virtual storage area network or any of the regular domain field values for a new virtual storage area network. The reserved domain field value is a domain field value that is not to be explicitly used in a Fibre Channel network for Fibre Channel identifiers according to the applicable Fibre Channel industry standards.

    摘要: In one embodiment, a technique for performing partial build fabric operations when merging two or more Fibre Channel fabrics is provided. By maintaining a Principal Switch already assigned for one of two merging fabrics, a limited “partial build” may be performed for the other merging fabric. As a result, the time required for a Principal Switch selection phase may be greatly reduced.
