In accordance with one embodiment of the present invention, a host bus adapter for implementing a first port of a node on a network of nodes interconnected through an intelligent connection system comprising: a transceiver providing a physical interface for the first port; and a protocol controller that transmits a notification to the intelligent connection system on behalf of a remote second port indicating that the second port may have failed when the second port fails to communicate with the first port.

Method, system, and apparatus for executing input/output operations. The method including selecting a level of error recovery for input/output operations, receiving a request to execute the input/output operation, attempting the input/output operation, and when the input/output operation fails, performing the level of error recovery specified. The selection of the error recovery level may be done by a user, or embedded within the input/output request itself.

Error recovery for input/output operations

The invention, in its various aspects and embodiments, includes a method for uniquely identifying a device on a SCSI bus. The method first queries the device with a first SCSI command to obtain general identification information. Next, a first set of identification information for the device is extracted from the general identification information. A second SCSI command is then determined from the first set of identification information. Next, the device is queried with the second SCSI command to obtain general device identifiers. A second set of identification information for the device is then extracted from the general device identifiers. Then, an unique identifier is formulated from the first and second sets of information.

Software mechanism for unique identification of SCSI device

A computer system includes a SCSI bus for which domain validation processes can occur transparently (i.e., without device driver involvement). The system includes a SCSI bus adapter which runs firmware to support the domain validation process. The adapter initiates the domain validation process with respect to the peripheral devices on the SCSI bus. If any one or more SCSI peripheral device reports the presence of sense data to the SCSI adapter, the adapter records the sense data in its memory, or at least records that sense data was reported by a peripheral device. Then, towards or at completion of the domain validation process, the bus adapter resets the entire bus, or alternatively, resets only those peripheral devices that actually reported the presence of sense data. By resetting the devices, their device drivers will automatically initialize the devices thereby making the drivers again aware of the state of the devices.
