Abstract: In traditional Fiber Channel systems, remote devices connected to the Fiber Channel network using a bridge or included in a storage enclosure are not tracked. If a remote device, such as a SCSI disk device, is removed or swapped, data errors such as data corruption can result. A device identifier corresponding to the remote device is obtained from the remote device. The device identifier may include the remote device's serial number and other identifying information pertaining to the device. The first time the remote device is used, the device identifier is obtained and stored by the Fiber Channel device using the remote device. This device identifier is compared with subsequently obtained identifiers. If the identifiers match, communication with the remote device occurs. However, if the identifiers do not match, an error condition is raised indicating that the remote device has been removed or swapped.

Abstract: In traditional Fibre Channel systems, remote devices connected to the Fibre Channel network using a bridge or included in a storage enclosure are not tracked. A device identifier corresponding to the remote device is obtained from the remote device. The device identifier may include the remote device's serial number and other identifying information pertaining to the device. The remote device's vendor and product identifiers are retrieved and matched against a table of known vendor/product identifiers. If the match is successful, a predefined routine is located based on the match. The predefined routine is repeatedly used to retrieve the device identifier from the remote device. Communication with the remote device continues while the device identifier matches a previously stored device identifier corresponding to the device. When the device identifier no longer matches, an error occurs indicating that the remote device has been removed or swapped.

Abstract: A GPS device is used in conjunction with a device, such as a SAN device, to record and track the device's location. A device can periodically report its location to one or more computer systems that track device locations. Another device can send a request to other devices requesting the devices' geographic location. The devices, in turn, respond with data corresponding to their geographic location. In the event of a catastrophe or other event rendering devices in one area inoperable, one of the computer systems can be used to identify a location of another device that includes similar data. The GPS data corresponding to a device can also be used to identify a technician that should respond to a device maintenance or repair event.

The first time the remote device is used, the device identifier is obtained and stored by the Fibre Channel device using the remote device. The device identifier is obtained by repeatedly querying the remote device to identify the device's serial number. Communication with the remote device takes place if the identified device identifier matches the previously stored device identifier. An error condition occurs if the identifiers do not match.
