Chapter 8 DLT4000 SCSI Interface 8.1 Overview This chapter details the SCSI Protocol features the DLT4000 drive implements. The following sections do not fully reiterate the ANSI SCSI messages, options and command code specifications, but describe the supported commands, messages, and options supported, and the error recovery procedures. 8.2 General SCSI Bus Operation 8.2.1 Data Transfer The DLT4000 drive supports asynchronous and synchronous data transfers.
DLT4000 SCSI Interface 8.2.2 Initiator/Target Operation The DLT4000 drive does not act as an initiator on the SCSI bus. Therefore, the device will not do any of the following: • Generate unsolicited interrupts to the host • Initiate its own SCSI commands • Assert bus reset 8.2.3 SCSI IDs and Logical Unit Numbers (LUNs) The DLT4000 drive with optional medium changer has two logical units. The tape drive will always appear as LUN 0.
DLT4000 SCSI Interface 8 2. Unit Attention Condition Queued Unit Attentions are implemented on this device, and are maintained following circumstances: • • BUS Reset Bus Device Reset message • media may have changed asynchronously • • A firmware (microcode) update has completed a cartridge is loaded, Power Up and Not-ready to Ready Transition Unit Attentions are created.
DLT4000 SCSI Interface 8.2.6 Data Cache and Tape Write Interaction The DLT4000 drive contains a data cache that buffers blocks (records) until they are written. This section defines specific times that blocks are written to the tape. A Mode Select parameter allows the data cache to be disabled (unbuffered mode). In this mode, every WRITE command will cause the data to be written to the media before the STATUS byte and the COMMAND COMPLETE message is returned to the host.
. . STATUS phase is requested by the initiator. The only exception is during error cases when the device Status bytes the tape drive returns are as follows: GO • REQUEST SENSE command should be sent following this status to determine • unable to accept a command from an otherwise acceptable initiator. The initiator • for commands issued with the LINK bit set. Following the return of this status, command.
DLT4000 SCSI Interface These commands are as follows: • INQUIRY • LOAD UNLOAD • LOG SENSE/SELECT • MODE SELECT • MODE SENSE • PREVENT/ALLOW MEDIUM REMOVAL • READ BLOCK LIMITS • READ BUFFER • READ ELEMENT STATUS • RECEIVE DIAGNOSTIC RESULTS • REQUEST SENSE • RESERVE/RELEASE UNIT • SEND DIAGNOSTIC (non-media access diagnostics) • WRITE BUFFER The TEST UNIT READY command is used to determine whether the tape drive would accept a media access command without returning CHECK CONDITIO
normal environment should be virtually free of bus parity errors Bus parity errors cause the drive to either retry the operation, go to STATUS phase, or Retrying of parity errors during Data Out Phase when writing is normally not done, but can be enabled by changing the EnaParErrRetry parameter in the VU EEROM device performance (the data stream on writes cannot be pipelined as well).
DLT4000 SCSI Interface 8 3 SCSI Message System purpose of physical path management. To support certain SCSI-1 initiators, an Identify message is not required by the should be an IDENTIFY, ABORT, or BUS DEVICE RESET message.
DLT4000 SCSI Interface ABORT (06h) This message is sent from the initiator to the target to clear, on the selected unit, the current I/O process. Buffered (cached) write operations will be completed if possible. The target goes directly to the BUS FREE phase after successful receipt of this message. Current settings of Mode Select parameters and reservations are not affected. Commands, data, and status for other initiators is not affected.
DLT4000 SCSI Interface When received from an initiator, the tape drive may respond in one of two ways. First, it may take the message as a request by the initiator to disconnect and comply by entering message in phase and sending the DISCONNECT message back to the initiator (possibly preceded by the SAVE DATA POINTERS message). In this case, it will delay a minimum of 200 µs before arbitrating for the bus again. Alternately, it may enter the message in phase and return MESSAGE REJECT.
DLT4000 SCSI Interface IDENTIFY (80h-FFh) These messages are sent either by the initiator or by the target to establish (or reestablish) the physical connection path between an initiator and target for a particular logical unit. The message byte consists of the following bits: Bit 7: Always set to one. Bit 6: Set by initiator if target is allowed to disconnect/reconnect. Bit 5: Must be set to zero ("Target Routines" not supported). Bit 4: Reserved. Must be set to zero. Bit 3: Reserved. Must be set to zero.
DLT4000 SCSI Interface directly to the BUS FREE state by releasing the BSY signal, signifying a catastrophic error. The target's response to this message is to switch to the MESSAGE IN phase and resend from the beginning all the bytes of the message which generated the original MESSAGE PARITY ERROR message. MESSAGE REJECT (07h) This message is sent from the initiator or target to indicate that the last message received was inappropriate or has not been implemented.
DLT4000 SCSI Interface Synchronous Data Transfer Request (SDTR) This extended message allows the target and initiator to agree on the values of the parameters relevant to synchronous transfers. DLT4000 drive will not initiate the Synchronous Data Transfer Request message, but relies on the Initiator to do so. The SDTR message has the following format: Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Extended Message Identifier – 01h Length = 3 Message Code = 1 (SDTR msg) Transfer Period (min=50.
DLT4000 SCSI Interface 8.4 Tape Drive SCSI Commands 8.4.1 Control Byte - Flag and Link Bits The control byte of the Command Descriptor Block contains the Flag and Link bits. Use of these bits is entirely initiator dependent. Setting the Link bit provides an automatic link to the next command, bypassing the usual ARBITRATION, SELECTION, and MESSAGE OUT phases which would normally occur between commands. All other bits in the Control Byte are considered to be reserved.

DLT4000 SCSI Interface 8.4.7.1 Operation of LOG SELECT The purpose of the LOG SELECT command is to allow the initiator to modify and initialize parameters within the logs supported by the device. There are two ways to initialize the log parameters. First, set the PCR bit in the LOG SELECT CDB; this clears all parameters. Secondly, individual pages can be cleared by specifying the log page and the parameter value as the log parameters. The following pages can be cleared in this manner.
DLT4000 SCSI Interface LOG SELECT PAGE FORMAT Each Log page will begin with a 4-byte header followed by n number of log parameter blocks (one block for each parameter code). Each block, except for parameter code 05h, will be 8 bytes. The parameter block for code 05h will be 12 bytes.

Appendix D EEROM Resident Bugcheck and Event Logs D.1 EEROM Packets (Last n Error Events) The DLT4000 products keep certain error and event logs in semi-permanent nonvolatile memory (EEROM) on the ECM. There is room for a total of 14 such information packets in EEROM, each consisting of 98 bytes (96 data bytes plus 2 control bytes) of information.

EEROM Resident Bugcheck and Event Logs D.3 PO/ST failure packets PO/ST failure packets are stored whenever the Power-On /Self-Test logic detects a failure of any kind. Each failure is encoded as a 4-byte vector. In some cases, multiple vectors may be stored, as shown in Figure D-3. Figure D-3 POST LOG Packet Layout D.4 Event Log packets Event logs are non fatal and can occur to log error or informative information regarding significant events.
