Chapter 4 SCSI Interface Chapter 4 SCSI Interface 4 This chapter details the SCSI Protocol features for the L200 library.
Chapter 4 SCSI Interface General SCSI Bus Operation General SCSI Bus Operation This section discusses general SCSI bus operation. Note: DLT tape drive commands are not discussed in this manual. These commands are described in the SCSI interface chapter of the product manual for your library drive option. Data Transfer 4 The L200 supports asynchronous and synchronous data transfers. The product has both differential and single ended interfaces.
Chapter 4 SCSI Interface General SCSI Bus Operation Unit Attention Condition 4 Queued Unit Attentions are implemented on this device, and are maintained separately for each Initiator. Unit Attentions are created in the following circumstances: • power on • Bus Reset • Bus Device Reset message • when the media may have changed asynchronously • another initiator changed the Mode Parameters It is not unusual for a firmware (microcode) update to complete two queued Unit Attentions.
Chapter 4 SCSI Interface General SCSI Bus Operation Status Phase 4 The library enters the status phase just once per command, unless the initiator requests a retry. The only exception is during error cases when the device goes immediately to bus free, as defined in the SCSI-2 standard. The library can return any of the following status bytes: • GOOD (00): This status indicates the library successfully completed the command. • CHECK CONDITION (02): A contingent allegiance condition occurred.
Chapter 4 SCSI Interface General SCSI Bus Operation Bus Parity Errors 4 Bus parity errors (i.e. single bit errors) are very serious because they imply the possibility of undetected double-bit errors on the bus, which most likely would result in undetected data corruption. On properly configured SCSI buses, parity errors are extremely rare. If any are detected, they should be addressed quickly by improving the configuration of the SCSI bus.
Chapter 4 SCSI Interface SCSI Message System SCSI Message System The message system allows an initiator and a target to communicate for the purpose of physical path management. To support certain SCSI-1 initiators, the library does not require an Identify message. If a message is sent by the initiator after the SELECTION phase, it should be an IDENTIFY, ABORT, or BUS DEVICE RESET message. In this case, if the library recovers a message other than those listed above, it will go directly to BUS FREE phase.
Chapter 4 SCSI Interface SCSI Message System Operation Code In/Out No-Op (No Operation) 08h Out Restore Pointers 03h In Save Data Pointer 02h In Message see page 61 Synchronous Data Transfer Request Wide Data Transfer Request Abort (06h) 4 03h In The initiator sends an abort message to the target to clear the current I/O process on the selected unit. The target goes directly to the BUS FREE phase after successful receipt of this message.
Chapter 4 SCSI Interface SCSI Message System Command Complete (00h) Disconnect (04h) 4 4 This message is sent from a target to an initiator to indicate that the execution of a command (or a series of linked commands) is complete and valid status has been sent to the initiator. After it has sent the message successfully, the target goes to the BUS FREE phase by releasing BSY.
Chapter 4 SCSI Interface SCSI Message System 03h - Wide Data Transfer Request 04h-7Fh - Reserved 80-FFh - Vendor Unique If the library receives an extended message which it does not support, it switches to message in phase and returns MESSAGE REJECT after all the bytes of the message have been transferred.
Chapter 4 SCSI Interface SCSI Message System Message Parity Error (09h) 4 This message is sent from the initiator to the target to indicate that one or more bytes in the last message it received had a parity error. To indicate that it intends to send the message, the initiator sets the ATN signal before it releases ACK for the REQ/ACK handshake of the message that has the parity error. This provides an interlock so that the target can determine which message has the parity error.
Chapter 4 SCSI Interface SCSI Message System Save Data Pointer (02h) 4 This message, sent from a target to the initiator, saves a copy of the present active Data pointer for the logical unit currently attached. As a target, the library sends this message before a disconnect during a data transfer. It does not send a SAVE DATA POINTER message if it intends to move directly to STATUS phase. When received as a target, it switches to message in phase and returns MESSAGE REJECT.
Chapter 4 SCSI Interface SCSI Message System A Wide Data Transfer Request (WDTR) message exchange is initiated by a SCSI device whenever a previously arranged transfer width agreement becomes invalid.
Chapter 5 Troubleshooting Guidelines Chapter 5 Troubleshooting Guidelines 5 This chapter contains user guidelines and descriptions of problems that may be encountered when operating the L200 library. Wherever applicable, corrective information has also been provided to assist in problem resolution. Several library problems produce error messages that are displayed on the operator control panel (OCP). See Appendix B, “OCP Error Messages and Error Definitions,”for more information.
Chapter 5 Troubleshooting Guidelines Avoiding Basic Problems Avoiding Basic Problems The following information will assist the user when troubleshooting the L200 library: Basic Library Operation • basic library operation • OCP button operation • operation failure • error conditions • power problems When operating the library: 5 • use DLTtape III, DLTtape IIIxt or DLTtape IV cartridges Caution: • Do not touch the exposed magnetic tape.
Chapter 5 Troubleshooting Guidelines Avoiding Basic Problems Operation Failure 5 Use the following guidelines if operation failure occurs. Write-Operation Failure 5 Some manual operations, if not performed correctly, may cause write operations to fail.
Chapter 5 Troubleshooting Guidelines Avoiding Basic Problems If the library power is disconnected when a cartridge is in transit between the elevator and magazine, the cartridge is moved into the magazine slot when power is restored.
