The Small Computer System Interface (SCSI) tape driver provides a standard tape drive interface as described in mtio(7). This is the tape driver for any Compaq SCSI tape device. Facilities are provided to allow the addition of third-party SCSI tape drives to the system. Refer to the ddr_config(8) and ddr.dbase(4) reference pages for instructions. For reads from Beginning of Media (BOM), the density of the tape is obtained from the drive. Autodensity selection is then used for all read operations. This means that reads are performed in the density of the tape. For writes from BOM, the density, compression, and fixed/variable blocking factor of the tape are set. The tape is written in the den- sity, compression, and fixed/variable blocking factor selected by the device special file name such as tape?_d0 device special files in dev/tape. See System Administration for more information on device special files. If the tape is not at BOM, and is partly written, the written portion of the tape determines the density, compression, and fixed/variable blocking factors for the write. Tape Media and Drive Compatibility Tables The following table lists the tape compatibility for CompacTape media and the TZ85, TZ86, TZ87, TZ88, TZ89, DLT4000, and DLT8000 tape drives: ----------------------------------------------------------------------------- Media Type Drive Type ----------------------------------------------------------------------------- CompacTapeI TZ30, TK50 CompacTapeII TZ30, TK50, TK70, TZ85, TZ86 CompacTapeIII TZ85, TZ86, TZ87, TZ88, TZ89, DLT4000, DLT8000 CompacTapeIIIXT TZ88, TZ89, DLT4000, DLT8000 CompacTapeIV TZ88, TZ89, DLT4000, DLT8000 ----------------------------------------------------------------------------- CompacTapeIII is also known as DLTtapeIII. CompacTapeIIIXT is also known as DLTtapeIIIxT. CompacTapeIV is also known as DLTtapeIV. The following table lists the tape compatibility for the TLZ04, TLZ06, TLZ07, TLZ09, TLZ10, SDT-7000, SDT-9000, and SDT-10000 tape drives: -------------------------------------------------------------- Media Type Drive Type -------------------------------------------------------------- DDS-1(60m) TLZ04, TLZ06, TLZ07, TLZ09, TLZ10, SDT-7000, SDT-9000, SDT-10000 DDS-1(90m) TLZ06, TLZ07, TLZ09, TLZ10, SDT-7000, SDT-9000, SDT-10000 DDS-2(120m) TLZ07, TLZ09, TLZ10, SDT-7000, SDT-9000, SDT-10000 DDS-3(125m) TLZ10, SDT-9000, SDT-10000 DDS-4(150m) SDT-10000 -------------------------------------------------------------- The following table lists the tape compatibility for the TZS20, SDX-300C, and SDX-500C tape drives: --------------------------------------------------- Media Type Drive Type Supported --------------------------------------------------- AIT 25 TZS20, SDX-300C, SDX-500C AIT 35 SDX-300C, SDX-500C AIT 50 SDX-500C --------------------------------------------------- Device Special Files and Tape Density Using a particular device special file with a certain tape format will indicate what density code, compression, capacity and I/O is sup- ported. It is also possible for administrators to customize which device special file names apply to what densities. Future extensions to device special files may also increase the number of alternative files that can be used with a particular device. The current range of possible device special files is: tape?_d0 to tape?_d7, where ? is a decimal number representing the identification number of the tape device. Normally, the _d1 suffix will always indicate the highest density used with compression, while the _d2 suffix will indicate the highest density witout compression. Note that the tape?_?? format device names correspond to the previous device names as shown in the following table: ------------------------------------------------------------------------- Previous Format in /dev New Formats in /dev/nrmt and /dev/rmt ------------------------------------------------------------------------- rmt?a tape?_d3 rmt?l tape?_d0 (d0 always maps to the low density) rmt?m tape?_d2 rmt?h tape?_d1 (d1 always maps to the high density) ------------------------------------------------------------------------- Two new device special file names now exist which will allow the user to select the highest density of the tape drive. These two device special filenames can be used for all devices which support auto-density select, even if there are no entries in the ddr.dbase file for the tape drive. By selecting this device special filename without any d0-d7 reference you will be selecting a density code of 00H, which will instruct the tape device to use the default density available for the tape type in the drive. Compression will be disabled for all I/O operations. By selecting this device special filename without any d0-d7 reference you will be selecting a density code of 00H, which will instruct the tape device to use the default density available for the tape type in the drive. Compression will be enabled for all I/O oper- ations. It is important that you ensure the device supports compression before you use this device special filename. If you have a requirement to support previous device names (such as local shell scripts or utilities), consult the System Administration guide for information on creating and using the rmt?? format for device special files. As it is possible to customize the device names, to determine how the tape device special file names correspond to the supported formats for a particular device, you can consult the /etc/ddr.dbase file and search for the device name. (See the reference page ddr.dbase(4) for information on this file) For example, the following entry appears for the TZS20 tape device: SCSIDEVICE # # Matches TZS20, TZS2 # Type = tape Name = "DEC" "TZS2" # PARAMETERS: TypeSubClass = 8mm, loader TagQueueDepth = 0 MaxTransferSize = 0x0ffffff # (16MB - 1) ReadyTimeSeconds = 90 # seconds DENSITY: # DensityNumber = 0,3,4,5,6,7 DensityCode = default CompressionCode = 0x0 Buffered = 0x1 DENSITY: # DensityNumber = 1,2 DensityCode = default CompressionCode = 0x1 Buffered = 0x1 From the DENSITY section of the entry you can determine which device special files apply: tape?_d0, or any device name with the suffix: _d3, _d4, _d5, _d6, and _d7. In this case, compression is set to Off(0x0). tape?_d1, or tape?_d2. In this case, compression is set to On(0x1) Tape Format Reference The following tables provide information for various tape drives. All of these tape drives support variable block size. Note that in the capacity column, a number followed by an asterisk (*) assumes a 2:1 compression ratio. The actual compression ratio may vary depending on the type of data being compressed. Note the following abbreviations that apply to these tables: CompacTape, such as CompacTapeIII Read and write I/O is supported Read only I/O is supported TZ85 Tape Drive Supported Formats ----------------------------------------------------------------------------- Format Device Special Density Compression Capacity Cartridge I/O File Name Code (GB) ----------------------------------------------------------------------------- TK50 tape?_d0-7 00h N/A 95M CT II ro TZ30 tape?_d0-7 00h N/A 95M CT II ro TZ85 tape?_d0-7 17h N/A 2.6 CT III rw TZ86 Tape Drive Supported Formats ----------------------------------------------------------------------------- Format Device Special Density Compression Capacity Cartridge I/O File Name Code (GB) ----------------------------------------------------------------------------- TK50 tape?_d0-7 00h N/A 95M CT II ro TZ30 tape?_d0-7 00h N/A 95M CT II ro TZ85 tape?_d0,3 17h N/A 2.6 CT III rw TZ86 tape?_d1,2,4-7 18h N/A 6.0 CT III rw ----------------------------------------------------------------------------- TZ87 Tape Drive Supported Formats ----------------------------------------------------------------------------- Format Device Special Density Compression Capacity Cartridge I/O File Name Code (GB) ----------------------------------------------------------------------------- TZ85 tape?_d3 17h N/A 2.6 CT III rw TZ86 tape?_d0 18h N/A 6.0 CT III rw TZ87 tape?_d2, 4-7 00h off 10.0 CT III rw TZ87 tape?_d1 00h on 20.0 * CT III rw ----------------------------------------------------------------------------- TZ88 / DLT4000 Tape Drive Supported Formats The DLT4000 is functionally equivalent to the TZ88 tape drive and the DLT4000 tape format is identical to the TZ88 tape format. ------------------------------------------------------------------------------ Format Device Special Density Compression Capacity Cartridge I/O File Name Code (GB) ------------------------------------------------------------------------------ TZ85 tape?_d3 17h N/A 2.6 CT III rw TZ86 tape?_d0 18h N/A 6.0 CT III rw TZ87 tape?_d2, 6-7 00h off 10.0 CT III rw TZ87 tape?_d1 00h on 20.0 * CT III rw TZ87 tape?_d4 19h off 15.0 CT III rw TZ87 tape?_d5 19h on 30.0 * CT III rw TZ88 tape?_d4, 5 N/A N/A 15/30 CT III XT ro TZ88 tape?_d2, 6-7 00h off 15.0 CT III XT rw TZ88 tape?_d1 00h on 30.0 * CT III XT rw DLT4000 tape?_d4, 5 N/A N/A 15/30 CT III XT ro DLT4000 tape?_d2, 6-7 00h off 15.0 CT III XT rw DLT4000 tape?_d1 00h on 30.0 * CT III XT rw TZ88 tape?_d4, 5 N/A N/A 20/40 CT IV ro TZ88 tape?_d2, 6-7 00h off 20.0 CT IV rw TZ88 tape?_d1 00h on 40.0 * CT IV rw DLT4000 tape?_d4, 5 N/A N/A 20/40 CT IV ro DLT4000 tape?_d2, 6-7 00h off 20.0 CT IV rw DLT4000 tape?_d1 00h on 40.0 * CT IV rw ------------------------------------------------------------------------------ TZ89 Tape Drive Supported Formats ------------------------------------------------------------------------------ Format Device Special Density Compression Capacity Cartridge I/O File Name Code (GB) ------------------------------------------------------------------------------ TZ85 tape?_d0,3 N/A N/A 2.6 CT III ro TZ85 tape?_d4 17h N/A 2.6 CT III rw TZ86 tape?_d0,3 N/A N/A 6.0 CT III ro TZ86 tape?_d5 18h N/A 6.0 CT III rw TZ87 tape?_d0,3 N/A N/A 10/20 CT III ro TZ87 tape?_d2,6-7 00h off 10.0 CT III rw TZ87 tape?_d1 00h on 20.0 * CT III rw TZ88 tape?_d0,3-5 N/A N/A 15/30 CT IIIXT ro DLT4000 tape?_d0,3-5 N/A N/A 15/30 CT IIIXT ro TZ88 tape?_d2,6-7 00h off 15.0 CT IIIXT rw TZ88 tape?_d1 00h on 30.0 * CT IIIXT rw DLT4000 tape?_d2,6-7 00h off 15.0 CT IIIXT rw DLT4000 tape?_d1 00h on 30.0 * CT IIIXT rw TZ88 tape?_d3 1ah off 20.0 CT IV rw TZ88 tape?_d0 1ah on 40.0 * CT IV rw DLT4000 tape?_d3 1ah off 20.0 CT IV rw DLT4000 tape?_d0 1ah on 40.0 * CT IV rw TZ89 tape?_d4,5 N/A N/A 20-70 CT IV ro TZ89 tape?_d2,6-7 00h off 35.0 CT IV rw TZ89 tape?_d1 00h on 70.0 * CT IV rw ------------------------------------------------------------------------------ DLT8000 Tape Drive Supported Formats The DLT2000 format is also known as the TZ87 format.

The 2 Gig density can only be written on a 2 Gig cartridge. The 1 Gig density can only be written on a 1 Gig cartridge. The 320/525 cartridge can be used to write 120/150/320/525 densities. With all fixed-block tape devices, when you use the dd command to transfer a file to tape you must use padding to complete a block by spec- ifying the conv=sync option. For example, the following two dd commands use the conv=sync option to transfer the /etc/motd file with a size of approximately 400 bytes to the QIC-format tape drives: dd if=/etc/motd of=/dev/tape/tape0_d2 bs=10k conv=sync dd if=/etc/motd of=dev/tape/tape0_d0 bs=512 conv=sync The data field of 1 also tells the driver not to continue scanning LUNs for this target when this attribute is found. Tape Support Refer to the Software Product Description (SPD) for information on the specific tape devices that are supported. Refer to the Systems and Options Catalog (SOC) for information on which devices are supported on the various system platforms. EXAMPLES
