4.Operation 4. Operation 4.1. Summary of LED Indications The SDX-800V have 3 LEDs. Each LED shows "Tape Motion", "Cleaning Request", and "Replace Tape" as defined. "Tape Motion" to show the tape motion in the drive. "Cleaning Request" to be on, when CLEANING is required. "Replace Tape" to be on, when the tape needs to be replaced. It should be on when a medium error occurred. All of three LEDs flash fast simultaneously, when the drive is in malfunction.
4.Operation 4.2. Operator Action 4.2.1. Powering up the SDX-800V After the initial installation of the SDX-800V has been verified, power can be applied to the unit. The +12V and +5V power must be applied simultaneously. (See Figure 2-5) The SDX-800V will execute a power-up diagnostic and then comes ready. Once the tape has been loaded the SDX-800V sends a CHECK CONDITION response on receipt of the next SCSI command from the host.
4.Operation AIT–1 AIT–2/3/3Ex AIT-E/1/2 Turbo 4.3. Internal Function The Load Sequence (Effective for non MIC cassette, only) Refer to 12.2.1. Fast Media Load/Unload (Effective for MIC cassette, only) 4.3.1. During load sequence, the following occurs: (1) The drive mechanism accepts the cassette and threads the tape. The tape is then moved to Beginning-of-Tape(BOT) and the Reference area is checked to find the tape format.
4.Operation 4.3.4. Diagnostic and Normal Status Displays This chapter describes LED displays while the SDX-800V is starting up. When power is turned on, the SDX-800V will go through its diagnostics to reach normal status. When a failure is detected during diagnostics, the LEDs show that the SDX-800V is out of order and needs to be repaired. Note: When power is turned on, the all LED on before the front panel test. 4.3.4.1. Diagnostic Status Display The SDX-800V starts with its Diagnostic function.

5.SCSI Interface 5. SCSI Interface 5.1. Introduction The Sony SDX-800V uses the SCSI interface to connect to the host system. The Small Computer System Interface (SCSI) is an industry standard interface, approved by the American National Standards Institute (ANSI). It is recommended that this document be used along with the ANSI standard document. The ANSI specification defines the interface in general while this document describes the specific implementation for this unit.
5.SCSI Interface 5.1.3. Supported Commands The following commands are supported. They include all Mandatory and Extended commands, most Optional commands.
5.SCSI Interface 5.2. SCSI Bus Operation 5.2.1. Typical SCSI Operation This example describes the typical SCSI bus sequence between the host and the drive. 1. After waiting for the bus clear time the Host arbitrates for the SCSI bus. It does this by asserting BSY and the data line corresponding to its bus ID. If any other devices wish to compete for the bus, they also assert BSY and the appropriate data line. Each arbitrating device then inspects the data bus.
5.SCSI Interface 4. The I/O activity from this point is controlled entirely by the target. The target initiates the COMMAND phase and reads in the Command Descriptor Block (CDB) from the Host. If the Host has sent an Identify message with the Disconnect permission bit set, then the target will immediately disconnect from the bus after the entire CDB has been received. 5. The Disconnect process occurs when the target initiates a MESSAGE IN phase and sends a DISCONNECT message back to the Host.
5.SCSI Interface 5.3.1. COMMAND COMPLETE (00h) This message is sent from a target to an initiator to indicate that the execution of a command or a series of linked commands has completed and valid status has been sent to the initiator. After successfully sending this message, the target goes to the BUS FREE phase by releasing BSY.
5.SCSI Interface The TRANSFER WIDTH EXPONENT field defines the transfer width to be used during DATA IN phases, and DATA OUT phases. The transfer width that is established applies to both SCSI devices. Valid transfer widths are 8 bits (m=00h) and 16 bits (m=01h) if all the protocol options bits are zero. The only valid transfer width is 16 bits (m=01h) if any of the protocol options bits are one. QAS_REQ bit is not supported and shall be set to zero. IU_REQ bit is not supported and shall be set to zero.
5.SCSI Interface Table 5-4: Synchronous Data Transfer Rates Transfer Period (hex) Transfer Rate (MB/s) - narrow Transfer Rate (MB/s)- wide 9 80 160 0A 40.0 80.0 0C 20.0 40.0 19 10.0 20.0 1F 8.0 16.0 26 2C 32 6.67 5.71 5.00 13.34 11.42 10.00 38 4.44 8.88 REQ/ACK offset: is the maximum number of REQ pulses allowed to be outstanding before the leading edge of its corresponding ACK pulse is received at the target. A REQ/ACK offset value of ZERO shall indicate asynchronous data transfer mode.
5.SCSI Interface The implied synchronous agreement shall remain in effect until a BUS DEVICE RESET message is received, until a hard reset condition occurs, or until one of the two SCSI devices elects to modify the agreement. The default data transfer mode is asynchronous data transfer mode. The default data transfer mode is entered at power on, after a BUS DEVICE RESET message, or after a hard reset condition. 5.3.2.3.
5.SCSI Interface Following target response (1) above, the implied agreement for wide data transfers shall be considered to be negated by both the initiator and the target if it the initiator asserts ATN and the first message out is either MESSAGE PARITY ERROR or MESSAGE REJECT. In this case, both devices shall go to eight-bit data transfer mode for data transfers between the two devices.
5.SCSI Interface 5.3.6. INITIATOR DETECTED ERROR (05h) This message is sent from an initiator to inform a target that an error (e.g.: parity error) has occurred that does not prevent the target from re-trying the operation. At this point, present pointer integrity is not assured. A RESTORE POINTERS message or a disconnect followed by a re-selection, will cause the pointers to be restored to their previously defined state.
5.SCSI Interface 5.3.11. BUS DEVICE RESET (0Ch) This message is sent from an initiator to direct a target to clear all current commands. Upon recognizing this message, the currently executing command will be aborted and the drive will proceed to the BUS FREE state. The drive will then execute a hard reset which will leave the drive in a state as if it had been power-cycled. All data in the buffer will be written to tape before the reset is performed.
5.SCSI Interface 5.4. Status Specification A Status byte is sent from the drive to the Host during the STATUS phase at the termination of each command as specified in the SCSI specification, unless the command has been cleared by an ABORT message, by a BUS DEVICE RESET message, or by a hard RESET. The Status bytes that will be return are: 00h GOOD: This status indicates that the drive has successfully completed the command.
5.SCSI Interface 10h INTERMEDIATE GOOD: This status is returned for every command in a series of linked commands (except the last command), unless an error, exception or abnormal condition causes a CHECK CONDITION status or RESERVATION CONFLICT status to be set. If this status is not returned, the chain of linked commands is broken; no further commands in the series are executed.

This command may also be used to request a retention function. IMMED: If this bit is set, status is returned as soon as the load or unload operation is initiated.
LOAD/UNLOAD 6.Command Specification When the drive receives the UNLOAD, the tape is rewound to BOM and ejected. The operator must reload the drive manually. If, however, the drive has previously received a PREVENT MEDIA REMOVAL (with prevent bit set) command, the tape is retained in the drive. A subsequent LOAD command will load and position the tape at BOP ZERO. If an UNLOAD was sent instead, the drive would return NOT READY and the tape would remain within the drive.

12. Appendix E 12. APPENDIX E: Medium Auxiliary Memory Attribute 12.1. INTRODUCTION This section will outline the design specifications for the implementation of selected Medium Auxiliary Memory (MAM) attributes. 12.2. OVERVIEW An increasing number of media types are incorporating small memory components into their products.
12. Appendix E Note: The above information has been taken from an unofficial version of the SCSI-3 Stream Commands. In case of any conflict, the published ANSI standard prevails. Table 12-1 Bit 7 Byte 0 1 2 3 4 5 6 5 Reserved 4 3 2 OPERATION CODE ( 1Bh) Reserved Reserved Reserved HOLD EOT CONTROL 1 0 IMMED RETEN LOAD Note: For non-memory component media, the device firmware ignores the above command and threads the tape in order to provide the required data. 12.5.
12. Appendix E Table 12-3: MAM Attribute states Attribute Type Medium or Device Attribute State Read Only Unsupported Host Nonexistent Read/Write Description An application server may read the contents of the attribute with the READ ATTRIBUTE command, but an attempt to clear or change the attribute using the WRITE ATTRIBUTE command shall result in the command being terminated with a CHECK CONDITION status. When the READ ONLY bit is one, the attribute is in the read only state.
12. Appendix E The READ ONLY bit indicates whether the attribute is in the read only state. If the READ ONLY bit is one, the attribute is in the read only state. If the READ ONLY bit is zero, the attribute is in the read/write state. The FORMAT field (table 12-5) specifies the format of the data in the ATTRIBUTE VALUE field. ATTRIBUTES defined by this standard include a requirement for the contents of the FORMAT field.
12.
12. Appendix E 0007h INITIALIZATION COUNT: Indicates the number of times that a device server has logically formatted the medium. This figure is cumulative over the life of the medium and shall never be reset. 020Ah, 020Bh, 020Ch, 020Dh DEVICE VENDOR/SERIAL NUMBER AT LAST LOAD, DEVICE VENDOR/SERIAL NUMBERAT LOAD – 1, DEVICE VENDOR/SERIAL NUMBER AT LOAD – 2 AND DEVICE VENDOR/SERIAL NUMBER AT LOAD –3: Give a rolling history of the last four device servers in which the medium has been loaded.
12.
12. Appendix E The CURRENT AMOUNT OF DATA READ field indicates the amount of data physically read from the medium during this load of the medium. This value is expressed in increments of 1048576 bytes (e.g., a value of one means 1048576 bytes, two means 2097152 bytes, etc.). The CURRENT READ RETRIES COUNT field indicates the number of times a read retry was performed during this load of the medium. The exact definition of the error counters is not part of this standard.
12.
12. Appendix E COUNT fields are as defined for MEDIUM USAGE HISTORY except that they refer to the partition identified by the CDB PARTITION NUMBER field rather than the whole medium. The CHANGE PARTITION COUNT field indicates the number of times that switches to the partition specified by the PARTITION NUMBER field in the CDB have been performed on the medium. This count accumulates over the life of the medium but it is reset to zero after a medium format.
12. Appendix E Note: The Formatted Density Code ID 0006h, which is in the Device Common Attribute section and the Medium Density Code ID 0405h, which is located in the Medium Common Attributes section, will need to be use in some cases in conjunction in determining the media format. The MEDIUM MANUFACTURE DATE: Identifies the date of manufacture of the medium. The format is YYYYMMDD. The MAM CAPACITY: Is the total capacity of the MAM, in bytes, at manufacture time.
12. Appendix E Note: It is intended that this field provide a unique vendor identification of the vendor who wrote the Host Common attributes. In the absence of a formal registration procedure, T10 maintains a list of vendor identification codes in use. Vendors are requested to voluntarily submit their identification codes to T10 to prevent duplication of codes. APPLICATION NAME: Contains the name of the application client. APPLICATION VERSION contains the version of the application client.
13. Appendix F 13. APPENDIX F: AIT based WORM system 13.1. Important Notice (1) AIT WORM cartridges come equipped with Remote MIC. (2) A new AIT WORM cartridge can be initialized to use either AIT native mode or DDS emulation mode.

15. Appendix H 15. APPENDIX H: GLOSSARY This glossary includes many terms that are useful when working with the SONY DDS tape drive. Not all terms are used within this manual. Amble: A frame used to separate groups. It has a Logical Frame Number of ZERO. The Main Data Area contains only a valid header. ANSI: American National Standards Institute, which sets standards for, amongst other things, SCSI and the safety of electrical devices.
15. Appendix H Group: A fixed capacity set of frames written onto or read from the tape. A group contains one index and can contain several records, partial records, File-marks and Set-marks. Hard Error: A Hard Error is an un-correctable data error. During writing, this is defined as being uncorrected after the RAW retry limit has been exceeded. During reading, a hard error is logged if a group is un-correctable.
15. Appendix H Tape Log: The Tape Log contains details of the history of a tape, the total number of groups written, of RAW retries, of groups read, of C3 ECC retries, and of loads. The log is copied into RAM when the tape is loaded into the SDX-800V, updated as the tape is used, and written back into the System area on the tape when it is unloaded. Tape Write Protect, power failure or reset will losethe log data maintained in RAM.
