Abstract: Provide access to storage resources of a storage device over a data storage fabric. Allow a zone manager of a first switch to assign a zone group to one of a plurality of phys of an expander of the storage device to allow the first switch to access storage resources of the storage device. If status of the phy that is assigned a zone group indicates a disconnection condition with the first switch, then configure the zone group of the expander of the storage device to prevent access to the storage resources of the storage device. If after the disconnection condition, the status of the phy indicates a reconnection condition with a second switch, then allow a zone manager of the second switch to assign a zone group to the phy to allow the second switch to access storage resources of the storage device.

Abstract: In one example, a method for assigning zone groups to a physical storage enclosure includes comparing a first signature assigned to a number of first storage devices in an online physical storage enclosure against a second signature assigned to a number of second storage devices in a first offline physical storage enclosure of a number of offline physical storage enclosures. The method may further include, in response to a determination that the first signature matches the second signature, copying zone groups from the first offline physical storage enclosure associated with the second signature to the online physical storage enclosure.

Abstract: A hardware device detects change messages broadcast within a system. The system includes the hardware device, one or more controller devices, one or more expander devices, and one or more target devices interconnected among one another. The hardware device determines whether the change messages were broadcast within the system every first period of time or less for at least a second period of time, the first period of time less than the second period of time. In response to determining that the change messages were broadcast within the system every first period of time or less for at least the second period of time, the hardware devices signals that an error has been detected.

Abstract: An example disclosed is directed to a switch. The switch includes a communication interface and a discovery module. The discovery module is to receive a registration request for bulk discovery from an initiator device via the communication interface. The discovery module is further to receive a change indication specifying that a change has occurred in a fabric associated with the switch, and update a data model based on the received change indication to generate an updated data model. The discovery module then filters the updated data model to generate a filtered data model, and sends the filtered data model to the initiator device via the communication interface.
