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 HP SCSI tape
device. Facilities are provided which enable you to add
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 density, compression, and
fixed/variable blocking factor selected by the device special
file name such as tape?_d0 device special files
located in dev/tape. See the System Administration guide
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 [Toc] [Back]

Device Special Files and Tape Density [Toc] [Back]
Using a particular device special file with a certain tape
format will indicate what density code, compression,
capacity and I/O is supported. 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/tape and /dev/ntape
------------------------------------------------------------------------
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 operations. 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 [Toc] [Back]
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

The SDX-300C format is also known as the TZS20 format.
The following formats are supported for the TZK10 QIC-format
tape drive: QIC-24 (re) 512-byte block size; QIC-120
and QIC-150 (rw) 512-byte block size; and QIC-320 (rw)
variable block size. With QIC-format tapes, except
QIC-320 and QIC-525, all read and write operations must be
in multiples of the block size because record boundaries
are not preserved. Use the following device special File

The following formats are supported for the TZK11 QIC-format
tape drive: QIC-24 (read only) 512-byte block size;
QIC-120 and QIC-150 (rw) 512-byte block size; and
QIC-320/525/1Gig/2Gig (rw) variable block size. With QICformat

The TZK11 tape drive uses autodensity select feature of
the drive. 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 specifying 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 [Toc] [Back]
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.
All diagnostic messages are sent to the error logger subsystem.
The following example shows the configuration specification
that you might have for a DEC 3000 Model 500 system
with a PMAZC controller in slot 0 and KZTSA devices in
slots 1 and 2:
bus tc0 at nexus? bus tcds0 at tc0 slot 6 vector tcdsintr
# onboard scsi bus tcds1 at tc0 slot 0 vector tcdsintr
# PMAZC in tc slot 0 bus tza0 at tc0 slot 1 vector kztsaintr
# KZTSA in tc slot 1 bus tza1 at tc0 slot 2
vector kztsaintr # KZTSA in tc slot 2 controller
scsi0 at tcds0 slot 0 vector scsiintr # Internal port controller
scsi1 at tcds0 slot 1 vector scsiintr # External
