Appl. No.:

10/012616

Inventors:

Mark A. Slutz - Colorado Springs CO
Erik Paulsen - Colorado Springs CO
Carl E. Gygi - Colorado Springs CO

Assignee:

LSI Logic Corporation - Milpitas CA

International Classification:

G06F 1300

US Classification:

710104, 710 8, 713100

Abstract:

A communications layer is provided between a host-based SCSI initiator and a SCSI target device to fully automate the validation process. The communications layer allows the host to direct variation and modification of the target parameters and behavior using vendor unique commands. The behavioral modification aims to establish interoperability by conforming the behavior of the target to the host behavior. The host-based initiator transports a suitable command structure to the target device containing appropriate ones of the vendor unique commands and associated parameter data. The target executes and otherwise processes the command structure to effectuate a reconfiguration according to the specifics of the command code. The command code is sufficient to fully reconfigure the SCSI target. Accordingly, the reconfiguration process is carried out in a fully automated fashion.

International Classification:

H01M 3102

US Classification:

324539, 439502

Abstract:

A signal testing implementation provides significant advantages over conventional signal testing techniques. According to an exemplary embodiment, an apparatus for enabling signal testing such as SCSI signal testing in a test configuration includes a portable cable environment having a plurality of cables exhibiting a plurality of lengths and impedances. A user can selectively connect any one of the cables between a host device such as a server and a target device such as a disk subsystem. Signal measurement connectors which are connectable to the portable cable environment may be provided. According to an embodiment, each of the signal measurement connectors includes one or more test measurement points to enable collection of signal testing results.

International Classification:

G11B 20/20
H03M 13/00

US Classification:

714758, 714700

Abstract:

A method and apparatus for generating a CRC (cyclic redundancy check)/parity error in network environment. A SCSI (small computer systems interface) bus expander such as an Ultra320 bus expander or the like is added between a sending device and a receiving device. The sending device-receiving device pair may execute a training session to determine the skew compensation. During the training session, the SCSI bus expander may figure out timing differences due to skew and adjusts the timing of each data signal to compensate for skew. For each data signal, a compensated time may be obtained. The compensated time may then be modified through a JTAG (Joint Test Action Group) port of the SCSI bus expander. The compensated times may be adjusted such that a CRC/parity error is generated on every I/O (input/output) or just some I/Os to the receiving device. By intentionally generating a CRC/parity error, the response of the devices in the SCSI environment to a CRC/parity error may be evaluated during an input/output (I/O) test.

Abstract:

A method and system for performing diagnostics and validation operations on a device under test uses near natural language commands. A host machine controls the testing either locally or remotely, such as through the Internet. Various options for running a test or battery of tests on the device under test include entering commands through a prompt line on a graphical user interface, reading commands from a file, or manipulating graphical objects representing components or devices and operations on a graphical user interface. A script may serve as a metric to determine the successfulness of a test or battery of tests of the device under test.

International Classification:

G06F 11/00

US Classification:

714 43

Abstract:

The present invention is a method and system for providing a complete validation of an initiator and target within bus architecture. A target's behavior may be controlled by an initiator. Control of the target may be through execution of initiator commands including vendor unique commands relating to desired characteristics for testing. The initiator's response to the target's behavior may be verified due to the handshaking communication protocol between a target and initiator. Additionally, by altering the behavior of the target to test initiator response, a target's behavior is also validated.

US Classification:

714715

Abstract:

Methods and structures within a SAS domain for automated tuning performance of a coupled pair of transceivers. In one aspect hereof, control registers of a transmitting transceiver coupled to a receiving transceiver are adjusted to a plurality of distinct combinations of settings. For each distinct setting, a test pattern may be transmitted from the transmitting transceiver to the receiving transceiver. Status registers of the transmitting transceiver and of the receiving transceiver may be read to identify errors in the transmission. Identified errors are counted for each for distinct setting of the control registers to determine a preferred setting to best tune operation of the transceiver pair. The testing may be performed by any SAS initiator device or SAS expander acting as an initiator and may be performed on any coupled pair of transceiver in the SAS domain.
