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: A SAS expander that includes a storage management module to cause the SAS expander to configure zoning of targets coupled to the SAS expander based on zone configuration rules. The storage management to cause, in response to receipt of a command to enter an expander reduced functionality mode of operation, the SAS expander to prevent initiators access to the targets coupled to the SAS expander and to allow update of expander functionality module for controlling operation of the SAS expander. The storage management module to cause, upon completion of the expander reduced functionality mode of operation, the SAS expander to reconfigure the zoning of the targets coupled to the SAS expander based on the zone configuration rules and to allow initiators access to the targets coupled to the SAS expander.

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.
