If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
any other SCSI device under Linux, say Y and make sure that you know
the name of your SCSI host adapter (the card inside your computer
that "speaks" the SCSI protocol, also called SCSI controller),
because you will be asked for it.
You also need to say Y here if you have a device which speaks
the SCSI protocol. Examples of this include the parallel port
version of the IOMEGA ZIP drive, USB storage devices, Fibre
Channel, and FireWire storage.
To compile this driver as a module, choose M here and read
<file:Documentation/scsi/scsi.txt>.
The module will be called scsi_mod.
However, do not compile this as a module if your root file system
(the one containing the directory /) is located on a SCSI device.

The OnStream SC-x0 SCSI tape drives cannot be driven by the
standard st driver, but instead need this special osst driver and
use the /dev/osstX char device nodes (major 206). Via usb-storage,
you may be able to drive the USB-x0 and DI-x0 drives as well.
Note that there is also a second generation of OnStream
tape drives (ADR-x0) that supports the standard SCSI-2 commands for
tapes (QIC-157) and can be driven by the standard driver st.
For more information, you may have a look at the SCSI-HOWTO
<http://www.tldp.org/docs.html#howto> and
<file:Documentation/scsi/osst.txt> in the kernel source.
More info on the OnStream driver may be found on
<http://linux1.onstream.nl/test/>
Please also have a look at the standard st docu, as most of it
applies to osst as well.

tristate "SCSI generic support"
depends on SCSI
---help---
If you want to use SCSI scanners, synthesizers or CD-writers or just
about anything having "SCSI" in its name other than hard disks,
CD-ROMs or tapes, say Y here. These won't be supported by the kernel
directly, so you need some additional software which knows how to
talk to these devices using the SCSI protocol:
For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
writer software look at Cdrtools
(<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
and for burning a "disk at once": CDRDAO
(<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
For other devices, it's possible that you'll have to write the
driver software yourself. Please read the file
<file:Documentation/scsi/scsi-generic.txt> for more information.
To compile this driver as a module, choose M here and read
<file:Documentation/scsi/scsi.txt>. The module will be called sg.
If unsure, say N.

This is a driver for SCSI media changers. Most common devices are
tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
don't need this for those tiny 6-slot cdrom changers. Media
changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
If you have such hardware and want to use it with linux, say Y
here. Check <file:Documentation/scsi/scsi-changer.txt> for details.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/kbuild/modules.txt> and
<file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
If unsure, say N.

it has an enclosure device. Selecting this option will just allow
certain enclosure conditions to be reported and is not required.
comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
depends on SCSI
config SCSI_MULTI_LUN
bool "Probe all LUNs on each SCSI device"
depends on SCSI
help
If you have a SCSI device that supports more than one LUN (Logical
Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
can say Y here to force the SCSI driver to probe for multiple LUNs.
A SCSI device with multiple LUNs acts logically like multiple SCSI
devices. The vast majority of SCSI devices have only one LUN, and
so most people can say N here. The max_luns boot/module parameter
allows to override this setting.
config SCSI_CONSTANTS
bool "Verbose SCSI error reporting (kernel size +=12K)"
depends on SCSI
help
The error messages regarding your SCSI hardware will be easier to
understand if you say Y here; it will enlarge your kernel by about
12 KB. If in doubt, say Y.
config SCSI_LOGGING
bool "SCSI logging facility"
depends on SCSI
---help---
This turns on a logging facility that can be used to debug a number
of SCSI related problems.
If you say Y here, no logging output will appear by default, but you
can enable logging by saying Y to "/proc file system support" and
"Sysctl support" below and executing the command
echo <bitmask> > /proc/sys/dev/scsi/logging_level
where <bitmask> is a four byte value representing the logging type
and logging level for each type of logging selected.
There are a number of logging types and you can find them in the
source at <file:drivers/scsi/scsi_logging.h>. The logging levels
are also described in that file and they determine the verbosity of
the logging for each logging type.
If you say N here, it may be harder to track down some types of SCSI
problems. If you say Y here your kernel will be somewhat larger, but
there should be no noticeable performance impact as long as you have
logging turned off.
config SCSI_SCAN_ASYNC
bool "Asynchronous SCSI scanning"
depends on SCSI
help
The SCSI subsystem can probe for devices while the rest of the
system continues booting, and even probe devices on different
busses in parallel, leading to a significant speed-up.
If you have built SCSI as modules, enabling this option can
be a problem as the devices may not have been found by the
time your system expects them to have been. You can load the
scsi_wait_scan module to ensure that all scans have completed.
If you build your SCSI drivers into the kernel, then everything
will work fine if you say Y here.
You can override this choice by specifying "scsi_mod.scan=sync"
or async on the kernel's command line.

The iSCSI Driver provides a host with the ability to access storage
through an IP network. The driver uses the iSCSI protocol to transport
SCSI requests and responses over a TCP/IP network between the host
(the "initiator") and "targets". Architecturally, the iSCSI driver
combines with the host's TCP/IP stack, network drivers, and Network
Interface Card (NIC) to provide the same functions as a SCSI or a
Fibre Channel (FC) adapter driver with a Host Bus Adapter (HBA).

WARNING This driver is an older aic7xxx driver and is no longer
under active development. Adaptec, Inc. is writing a new driver to
take the place of this one, and it is recommended that whenever
possible, people should use the new Adaptec written driver instead
of this one. This driver will eventually be phased out entirely.
This is support for the various aic7xxx based Adaptec SCSI
controllers. These include the 274x EISA cards; 284x VLB cards;
2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
motherboard based SCSI controllers from Adaptec. It does not support
the AAA-13x RAID controllers from Adaptec, nor will it likely ever
support them. It does not support the 2920 cards from Adaptec that
use the Future Domain SCSI controller chip. For those cards, you
need the "Future Domain 16xx SCSI support" driver.
In general, if the controller is based on an Adaptec SCSI controller
chip from the aic777x series or the aic78xx series, this driver
should work. The only exception is the 7810 which is specifically
not supported (that's the RAID controller chip on the AAA-13x
cards).
Note that the AHA2920 SCSI host adapter is *not* supported by this
driver; choose "Future Domain 16xx SCSI support" instead if you have
one of those.
Information on the configuration options for this controller can be
found by checking the help file for each of the available
configuration options. You should read
<file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
contacting the maintainer with any questions. The SCSI-HOWTO,

config IBMMCA_SCSI_ORDER_STANDARD
bool "Standard SCSI-order"
depends on SCSI_IBMMCA
---help---
In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
are assigned to the drive letters, starting with the lowest SCSI-id
(physical number -- pun) to be drive C:, as seen from DOS and
similar operating systems. When looking into papers describing the
ANSI-SCSI-standard, this assignment of drives appears to be wrong.
The SCSI-standard follows a hardware-hierarchy which says that id 7
has the highest priority and id 0 the lowest. Therefore, the host
adapters are still today everywhere placed as SCSI-id 7 by default.
In the SCSI-standard, the drive letters express the priority of the
disk. C: should be the hard disk, or a partition on it, with the
highest priority. This must therefore be the disk with the highest
SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
original definition of the SCSI-standard as also industrial- and
process-control-machines, like VME-CPUs running under realtime-OSes
(e.g. LynxOS, OS9) do.
If you like to run Linux on your MCA-machine with the same
assignment of hard disks as seen from e.g. DOS or OS/2 on your
machine, which is in addition conformant to the SCSI-standard, you
must say Y here. This is also necessary for MCA-Linux users who want
to keep downward compatibility to older releases of the
IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
June 1997).
If you like to have the lowest SCSI-id assigned as drive C:, as
modern SCSI-BIOSes do, which does not conform to the standard, but
is widespread and common in the PC-world of today, you must say N
here. If unsure, say Y.
config IBMMCA_SCSI_DEV_RESET

By default, SCSI-devices are reset when the machine is powered on.
However, some devices exist, like special-control-devices,
SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
not reset when switched on. If you say Y here, each device connected
to your SCSI-bus will be issued a reset-command after it has been
probed, while the kernel is booting. This may cause problems with
more modern devices, like hard disks, which do not appreciate these
reset commands, and can cause your system to hang. So say Y only if
you know that one of your older devices needs it; N is the safe
answer.

config SCSI_NCR53C8XX_DEFAULT_TAGS
int "default tagged command queue depth"
depends on SCSI_ZALON || SCSI_NCR_Q720
default "8"
---help---
"Tagged command queuing" is a feature of SCSI-2 which improves
performance: the host adapter can send several SCSI commands to a
device's queue even if previous commands haven't finished yet.
Because the device is intelligent, it can optimize its operations
(like head positioning) based on its own request queue. Some SCSI
devices don't implement this properly; if you want to disable this
feature, enter 0 or 1 here (it doesn't matter which).
The default value is 8 and should be supported by most hard disks.
This value can be overridden from the boot command line using the
'tags' option as follows (example):
'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
4, set queue depth to 16 for target 2 and target 3 on controller 0
and set queue depth to 10 for target 0 / lun 2 on controller 1.
The normal answer therefore is to go with the default 8 and to use
a boot command line option for devices that need to use a different
command queue depth.
There is no safe option other than using good SCSI devices.
config SCSI_NCR53C8XX_MAX_TAGS

This option allows you to specify the maximum number of commands
that can be queued to any device, when tagged command queuing is
possible. The default value is 32. Minimum is 2, maximum is 64.
Modern hard disks are able to support 64 tags and even more, but
do not seem to be faster when more than 32 tags are being used.
So, the normal answer here is to go with the default value 32 unless
you are using very large hard disks with large cache (>= 1 MB) that
are able to take advantage of more than 32 tagged commands.
There is no safe option and the default answer is recommended.
config SCSI_NCR53C8XX_SYNC
int "synchronous transfers frequency in MHz"
depends on SCSI_ZALON || SCSI_NCR_Q720
default "20"
---help---
The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
are respectively the maximum data transfer rates in mega-transfers
per second for each class. For example, a FAST-20 Wide 16 device is
able to transfer data at 20 million 16 bit packets per second for a
total rate of 40 MB/s.
You may specify 0 if you want to only use asynchronous data
transfers. This is the safest and slowest option. Otherwise, specify
a value between 5 and 80, depending on the capability of your SCSI
controller. The higher the number, the faster the data transfer.
Note that 80 should normally be ok since the driver decreases the
value automatically according to the controller's capabilities.
Your answer to this question is ignored for controllers with NVRAM,
since the driver will get this information from the user set-up. It
also can be overridden using a boot setup option, as follows
(example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
for FAST-20 synchronous data transfer (20 mega-transfers per
second).
The normal answer therefore is not to go with the default but to
select the maximum value 80 allowing the driver to use the maximum
value supported by each controller. If this causes problems with
your SCSI devices, you should come back and decrease the value.
There is no safe option other than using good cabling, right
terminations and SCSI conformant devices.

This option is only provided for safety if you suspect some SCSI
device of yours to not support properly the target-disconnect

TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants.
This driver works, but is still in experimental status. So better
have a bootable disk and a backup in case of emergency.
Documentation can be found in <file:Documentation/scsi/dc395x.txt>.
To compile this driver as a module, choose M here: the
module will be called dc395x.
config SCSI_DC390T
tristate "Tekram DC390(T) and Am53/79C974 SCSI support"
depends on PCI && SCSI
---help---
This driver supports PCI SCSI host adapters based on the Am53C974A
chip, e.g. Tekram DC390(T), DawiControl 2974 and some onboard
PCscsi/PCnet (Am53/79C974) solutions.
Documentation can be found in <file:Documentation/scsi/tmscsim.txt>.
Note that this driver does NOT support Tekram DC390W/U/F, which are
based on NCR/Symbios chips. Use "NCR53C8XX SCSI support" for those.
To compile this driver as a module, choose M here: the
module will be called tmscsim.
config SCSI_T128
tristate "Trantor T128/T128F/T228 SCSI support"
depends on ISA && SCSI
select SCSI_SPI_ATTRS
select CHECK_SIGNATURE
---help---
This is support for a SCSI host adapter. It is explained in section
3.11 of the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. If it doesn't work out
of the box, you may have to change some settings in
<file:drivers/scsi/t128.h>. Note that Trantor was purchased by
Adaptec, and some former Trantor products are being sold under the
Adaptec name.
To compile this driver as a module, choose M here: the
module will be called t128.
config SCSI_U14_34F
tristate "UltraStor 14F/34F support"
depends on ISA && SCSI && ISA_DMA_API
---help---
This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
The source at <file:drivers/scsi/u14-34f.c> contains some
information about this hardware. If the driver doesn't work out of
the box, you may have to change some settings in
<file: drivers/scsi/u14-34f.c>. Read the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Note that there is also
another driver for the same hardware: "UltraStor SCSI support",
below. You should say Y to both only if you want 24F support as
well.
To compile this driver as a module, choose M here: the
module will be called u14-34f.
config SCSI_U14_34F_TAGGED_QUEUE
bool "enable tagged command queueing"
depends on SCSI_U14_34F
help
This is a feature of SCSI-2 which improves performance: the host
adapter can send several SCSI commands to a device's queue even if
previous commands haven't finished yet.
This is equivalent to the "u14-34f=tc:y" boot option.
config SCSI_U14_34F_LINKED_COMMANDS
bool "enable elevator sorting"
depends on SCSI_U14_34F
help
This option enables elevator sorting for all probed SCSI disks and
CD-ROMs. It definitely reduces the average seek distance when doing
random seeks, but this does not necessarily result in a noticeable
performance improvement: your mileage may vary...
This is equivalent to the "u14-34f=lc:y" boot option.
config SCSI_U14_34F_MAX_TAGS
int "maximum number of queued commands"
depends on SCSI_U14_34F
default "8"
help
This specifies how many SCSI commands can be maximally queued for
each probed SCSI device. You should reduce the default value of 8
only if you have disks with buggy or limited tagged command support.
Minimum is 2 and maximum is 14. This value is also the window size
used by the elevator sorting option above. The effective value used
by the driver for each probed SCSI device is reported at boot time.
This is equivalent to the "u14-34f=mq:8" boot option.
config SCSI_ULTRASTOR
tristate "UltraStor SCSI support"
depends on X86 && ISA && SCSI
---help---
This is support for the UltraStor 14F, 24F and 34F SCSI-2 host
adapter family. This driver is explained in section 3.12 of the
SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. If it doesn't work out
of the box, you may have to change some settings in
<file:drivers/scsi/ultrastor.h>.
Note that there is also another driver for the same hardware:
"UltraStor 14F/34F support", above.
To compile this driver as a module, choose M here: the
module will be called ultrastor.
config SCSI_NSP32
tristate "Workbit NinjaSCSI-32Bi/UDE support"
depends on PCI && SCSI && !64BIT
help
This is support for the Workbit NinjaSCSI-32Bi/UDE PCI/Cardbus
SCSI host adapter. Please read the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here: the
module will be called nsp32.
config SCSI_DEBUG
tristate "SCSI debugging host simulator"
depends on SCSI
select CRC_T10DIF
help
This is a host adapter simulator that can simulate multiple hosts
each with multiple dummy SCSI devices (disks). It defaults to one
host adapter with one dummy SCSI disk. Each dummy disk uses kernel
RAM as storage (i.e. it is a ramdisk). To save space when multiple
dummy disks are simulated, they share the same kernel RAM for
their storage. See <http://www.torque.net/sg/sdebug.html> for more
information. This driver is primarily of use to those testing the
SCSI and block subsystems. If unsure, say N.
config SCSI_MESH
tristate "MESH (Power Mac internal SCSI) support"
depends on PPC32 && PPC_PMAC && SCSI
help
Many Power Macintoshes and clones have a MESH (Macintosh Enhanced
SCSI Hardware) SCSI bus adaptor (the 7200 doesn't, but all of the
other Power Macintoshes do). Say Y to include support for this SCSI
adaptor.
To compile this driver as a module, choose M here: the
module will be called mesh.
config SCSI_MESH_SYNC_RATE
int "maximum synchronous transfer rate (MB/s) (0 = async)"
depends on SCSI_MESH
default "5"
help
On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
drives a bus which is entirely internal to the machine (such as the
7500, 7600, 8500, etc.), the MESH is capable of synchronous
operation at up to 10 MB/s. On machines where the SCSI bus
controlled by the MESH can have external devices connected, it is
usually rated at 5 MB/s. 5 is a safe value here unless you know the
MESH SCSI bus is internal only; in that case you can say 10. Say 0
to disable synchronous operation.
config SCSI_MESH_RESET_DELAY_MS
int "initial bus reset delay (ms) (0 = no reset)"
depends on SCSI_MESH
default "4000"
config SCSI_MAC53C94
tristate "53C94 (Power Mac external SCSI) support"
depends on PPC32 && PPC_PMAC && SCSI
help
On Power Macintoshes (and clones) with two SCSI buses, the external
SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
machines which only have one SCSI bus, such as the 7200, also use
the 53C94. Say Y to include support for the 53C94.
To compile this driver as a module, choose M here: the
module will be called mac53c94.

If you have a Great Valley Products Series II SCSI controller,
answer Y. Also say Y if you have a later model of GVP SCSI
controller (such as the GVP A4008 or a Combo board). Otherwise,
answer N. This driver does NOT work for the T-Rex series of
accelerators from TekMagic and GVP-M.

depends on ATARI && SCSI
select SCSI_SPI_ATTRS
select NVRAM
---help---
If you have an Atari with built-in NCR5380 SCSI controller (TT,
Falcon, ...) say Y to get it supported. Of course also, if you have
a compatible SCSI controller (e.g. for Medusa).
To compile this driver as a module, choose M here: the
module will be called atari_scsi.
This driver supports both styles of NCR integration into the
system: the TT style (separate DMA), and the Falcon style (via
ST-DMA, replacing ACSI). It does NOT support other schemes, like
in the Hades (without DMA).
config ATARI_SCSI_TOSHIBA_DELAY
bool "Long delays for Toshiba CD-ROMs"
depends on ATARI_SCSI
help
This option increases the delay after a SCSI arbitration to
accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
use a Toshiba CD-ROM drive; otherwise, the option is not needed and
would impact performance a bit, so say N.
config ATARI_SCSI_RESET_BOOT
bool "Reset SCSI-devices at boottime"
depends on ATARI_SCSI
help
Reset the devices on your Atari whenever it boots. This makes the
boot process fractionally longer but may assist recovery from errors
that leave the devices with SCSI operations partway completed.
config MAC_SCSI
