A method and apparatus for assigning zone groups to a storage enclosure is disclosed. When a storage enclosure is added to a switch in a fabric, a signature of the storage enclosure will be created from the storage devices loaded in that enclosure. The signature will then be compared against the signature from a storage enclosure that is offline. When the signature matches the signature of the offline storage enclosure, the zone groups from the offline storage enclosure will be copied to the storage enclosure that was added to the fabric.

Zone group reassignment using storage device signatures

Methods, systems, and computer-readable media with executable instructions stored thereon for preventing deadlocks are provided. An inter-device mutex (IDM) can be locked for a first client. An error message can be sent to a second client in response to a received first lock command from the second client while the IDM is locked for the first client. A number of second lock commands from the second client while the IDM is locked for the first client can be received. The IDM can be unlocked for the first client in response to an unlock command received from the first client. The IDM can be locked for the second client in response to a received third lock command from the second client, wherein the third lock command is received subsequent to unlocking the IDM for the first client.

Deadlock prevention

Connection of an electronic device to a particular port of the network device is detected. It is determined based on zone information whether a misconnection has occurred. The zone information defines plural zones.
