23 the name of your SCSI host adapter (the card inside your computer
24 that "speaks" the SCSI protocol, also called SCSI controller),
25 because you will be asked for it.
27 You also need to say Y here if you have a device which speaks
28 the SCSI protocol. Examples of this include the parallel port
29 version of the IOMEGA ZIP drive, USB storage devices, Fibre
30 Channel, and FireWire storage.

105 tristate "SCSI OnStream SC-x0 tape support"
108 The OnStream SC-x0 SCSI tape drives cannot be driven by the
109 standard st driver, but instead need this special osst driver and
110 use the /dev/osstX char device nodes (major 206). Via usb-storage,
111 you may be able to drive the USB-x0 and DI-x0 drives as well.
112 Note that there is also a second generation of OnStream
113 tape drives (ADR-x0) that supports the standard SCSI-2 commands for
114 tapes (QIC-157) and can be driven by the standard driver st.
115 For more information, you may have a look at the SCSI-HOWTO
116 <http://www.tldp.org/docs.html#howto> and
117 <file:Documentation/scsi/osst.txt> in the kernel source.
118 More info on the OnStream driver may be found on

144 This enables the usage of vendor specific SCSI commands. This is
145 required to support multisession CDs with old NEC/TOSHIBA cdrom
146 drives (and HP Writers). If you have such a drive and get the first
147 session only, try saying Y here; everybody else says N.
150 tristate "SCSI generic support"
153 If you want to use SCSI scanners, synthesizers or CD-writers or just
154 about anything having "SCSI" in its name other than hard disks,
155 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
156 directly, so you need some additional software which knows how to
157 talk to these devices using the SCSI protocol:
159 For scanners, look at SANE (<http://www.sane-project.org/>). For CD
160 writer software look at Cdrtools
161 (<http://cdrecord.berlios.de/private/cdrecord.html>)
162 and for burning a "disk at once": CDRDAO
163 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
164 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
165 For other devices, it's possible that you'll have to write the
166 driver software yourself. Please read the file
167 <file:Documentation/scsi/scsi-generic.txt> for more information.
169 To compile this driver as a module, choose M here and read
170 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
175 tristate "SCSI media changer support"
178 This is a driver for SCSI media changers. Most common devices are
179 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
180 don't need this for those tiny 6-slot cdrom changers. Media
181 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
182 If you have such hardware and want to use it with linux, say Y
183 here. Check <file:Documentation/scsi/scsi-changer.txt> for details.
185 If you want to compile this as a module ( = code which can be
186 inserted in and removed from the running kernel whenever you want),
187 say M here and read <file:Documentation/kbuild/modules.txt> and
188 <file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
191 config SCSI_ENCLOSURE
192 tristate "SCSI Enclosure Support"
193 depends on SCSI && ENCLOSURE_SERVICES
195 Enclosures are devices sitting on or in SCSI backplanes that
196 manage devices. If you have a disk cage, the chances are that
197 it has an enclosure device. Selecting this option will just allow
198 certain enclosure conditions to be reported and is not required.
200 config SCSI_MULTI_LUN
201 bool "Probe all LUNs on each SCSI device"
204 Some devices support more than one LUN (Logical Unit Number) in order
205 to allow access to several media, e.g. CD jukebox, USB card reader,
206 mobile phone in mass storage mode. This option forces the kernel to
207 probe for all LUNs by default. This setting can be overriden by
208 max_luns boot/module parameter. Note that this option does not affect
209 devices conforming to SCSI-3 or higher as they can explicitely report
210 their number of LUNs. It is safe to say Y here unless you have one of
211 those rare devices which reacts in an unexpected way when probed for
214 config SCSI_CONSTANTS
215 bool "Verbose SCSI error reporting (kernel size +=12K)"
218 The error messages regarding your SCSI hardware will be easier to
219 understand if you say Y here; it will enlarge your kernel by about
220 12 KB. If in doubt, say Y.
223 bool "SCSI logging facility"
226 This turns on a logging facility that can be used to debug a number
227 of SCSI related problems.
229 If you say Y here, no logging output will appear by default, but you
230 can enable logging by saying Y to "/proc file system support" and
231 "Sysctl support" below and executing the command
233 echo <bitmask> > /proc/sys/dev/scsi/logging_level
235 where <bitmask> is a four byte value representing the logging type
236 and logging level for each type of logging selected.
238 There are a number of logging types and you can find them in the
239 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
240 are also described in that file and they determine the verbosity of
241 the logging for each logging type.
243 If you say N here, it may be harder to track down some types of SCSI
244 problems. If you say Y here your kernel will be somewhat larger, but
245 there should be no noticeable performance impact as long as you have
248 config SCSI_SCAN_ASYNC
249 bool "Asynchronous SCSI scanning"
252 The SCSI subsystem can probe for devices while the rest of the
253 system continues booting, and even probe devices on different
254 busses in parallel, leading to a significant speed-up.
256 If you have built SCSI as modules, enabling this option can
257 be a problem as the devices may not have been found by the
258 time your system expects them to have been. You can load the
259 scsi_wait_scan module to ensure that all scans have completed.
260 If you build your SCSI drivers into the kernel, then everything
261 will work fine if you say Y here.
263 You can override this choice by specifying "scsi_mod.scan=sync"
264 or async on the kernel's command line.
266 config SCSI_WAIT_SCAN
267 tristate # No prompt here, this is an invisible symbol.
271 # scsi_wait_scan is a loadable module which waits until all the async scans are
272 # complete. The idea is to use it in initrd/ initramfs scripts. You modprobe
273 # it after all the modprobes of the root SCSI drivers and it will wait until
274 # they have all finished scanning their buses before allowing the boot to
275 # proceed. (This method is not applicable if targets boot independently in
276 # parallel with the initiator, or with transports with non-deterministic target
277 # discovery schemes, or if a transport driver does not support scsi_wait_scan.)
279 # This symbol is not exposed as a prompt because little is to be gained by
280 # disabling it, whereas people who accidentally switch it off may wonder why
281 # their mkinitrd gets into trouble.

359 The iSCSI Driver provides a host with the ability to access storage
360 through an IP network. The driver uses the iSCSI protocol to transport
361 SCSI requests and responses over a TCP/IP network between the host
362 (the "initiator") and "targets". Architecturally, the iSCSI driver
363 combines with the host's TCP/IP stack, network drivers, and Network

730 depends on (ISA || EISA || PCI) && SCSI && ISA_DMA_API
732 This driver supports all EATA/DMA-compliant SCSI host adapters. DPT
733 ISA and all EISA I/O addresses are probed looking for the "EATA"
734 signature. The addresses of all the PCI SCSI controllers reported
735 by the PCI subsystem are probed as well.

744 config SCSI_EATA_TAGGED_QUEUE
745 bool "enable tagged command queueing"
748 This is a feature of SCSI-2 which improves performance: the host
749 adapter can send several SCSI commands to a device's queue even if
750 previous commands haven't finished yet.
751 This is equivalent to the "eata=tc:y" boot option.
753 config SCSI_EATA_LINKED_COMMANDS
754 bool "enable elevator sorting"
757 This option enables elevator sorting for all probed SCSI disks and
758 CD-ROMs. It definitely reduces the average seek distance when doing
759 random seeks, but this does not necessarily result in a noticeable
760 performance improvement: your mileage may vary...
761 This is equivalent to the "eata=lc:y" boot option.
763 config SCSI_EATA_MAX_TAGS
764 int "maximum number of queued commands"
768 This specifies how many SCSI commands can be maximally queued for
769 each probed SCSI device. You should reduce the default value of 16
770 only if you have disks with buggy or limited tagged command support.
771 Minimum is 2 and maximum is 62. This value is also the window size
772 used by the elevator sorting option above. The effective value used
773 by the driver for each probed SCSI device is reported at boot time.
774 This is equivalent to the "eata=mq:8" boot option.

778 depends on (ISA || EISA || PCI) && SCSI && BROKEN
780 This driver supports all EATA-PIO protocol compliant SCSI Host
781 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
782 host adapters could also use this driver but are discouraged from
783 doing so, since this driver only supports hard disks and lacks
784 numerous features. You might want to have a look at the SCSI-HOWTO,

797 other adapters based on the Future Domain chipsets (Quantum
798 ISA-200S, ISA-250MG; Adaptec AHA-2920A; and at least one IBM board).
799 It is explained in section 3.7 of the SCSI-HOWTO, available from
800 <http://www.tldp.org/docs.html#howto>.
802 NOTE: Newer Adaptec AHA-2920C boards use the Adaptec AIC-7850 chip
803 and should use the aic7xxx driver ("Adaptec AIC7xxx chipset SCSI

847 tristate "Generic NCR5380/53c400 SCSI PIO support"
848 depends on ISA && SCSI
849 select SCSI_SPI_ATTRS
851 This is a driver for the old NCR 53c80 series of SCSI controllers
852 on boards using PIO. Most boards such as the Trantor T130 fit this
853 category, along with a large number of ISA 8bit controllers shipped
854 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
855 you should select the specific driver for that card rather than
856 generic 5380 support.
858 It is explained in section 3.8 of the SCSI-HOWTO, available from
859 <http://www.tldp.org/docs.html#howto>. If it doesn't work out

882 bool "Enable NCR53c400 extensions"
883 depends on SCSI_GENERIC_NCR5380
885 This enables certain optimizations for the NCR53c400 SCSI cards.
886 You might as well try it out. Note that this driver will only probe
887 for the Trantor T130B in its default configuration; you might have
888 to pass a command line option to the kernel at boot time if it does
889 not detect your card. See the file
890 <file:Documentation/scsi/g_NCR5380.txt> for details.
893 tristate "IBMMCA SCSI support"
894 depends on MCA && SCSI
896 This is support for the IBM SCSI adapter found in many of the PS/2
897 series computers. These machines have an MCA bus, so you need to
898 answer Y to "MCA support" as well and read
899 <file:Documentation/mca.txt>.
901 If the adapter isn't found during boot (a common problem for models
902 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
903 option, where <pun> is the id of the SCSI subsystem (usually 7, but
904 if that doesn't work check your reference diskette). Owners of
905 model 95 with a LED-matrix-display can in addition activate some
906 activity info like under OS/2, but more informative, by setting
907 'ibmmcascsi=display' as an additional kernel parameter. Try "man
908 bootparam" or see the documentation of your boot loader about how to
909 pass options to the kernel.
911 To compile this driver as a module, choose M here: the
912 module will be called ibmmca.
914 config IBMMCA_SCSI_ORDER_STANDARD
915 bool "Standard SCSI-order"
916 depends on SCSI_IBMMCA
918 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
919 are assigned to the drive letters, starting with the lowest SCSI-id
920 (physical number -- pun) to be drive C:, as seen from DOS and
921 similar operating systems. When looking into papers describing the
922 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
923 The SCSI-standard follows a hardware-hierarchy which says that id 7
924 has the highest priority and id 0 the lowest. Therefore, the host
925 adapters are still today everywhere placed as SCSI-id 7 by default.
926 In the SCSI-standard, the drive letters express the priority of the
927 disk. C: should be the hard disk, or a partition on it, with the
928 highest priority. This must therefore be the disk with the highest
929 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
930 original definition of the SCSI-standard as also industrial- and
931 process-control-machines, like VME-CPUs running under realtime-OSes
932 (e.g. LynxOS, OS9) do.
934 If you like to run Linux on your MCA-machine with the same
935 assignment of hard disks as seen from e.g. DOS or OS/2 on your
936 machine, which is in addition conformant to the SCSI-standard, you
937 must say Y here. This is also necessary for MCA-Linux users who want
938 to keep downward compatibility to older releases of the
939 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
942 If you like to have the lowest SCSI-id assigned as drive C:, as
943 modern SCSI-BIOSes do, which does not conform to the standard, but
944 is widespread and common in the PC-world of today, you must say N
945 here. If unsure, say Y.
947 config IBMMCA_SCSI_DEV_RESET
948 bool "Reset SCSI-devices at boottime"
949 depends on SCSI_IBMMCA
951 By default, SCSI-devices are reset when the machine is powered on.
952 However, some devices exist, like special-control-devices,
953 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
954 not reset when switched on. If you say Y here, each device connected
955 to your SCSI-bus will be issued a reset-command after it has been
956 probed, while the kernel is booting. This may cause problems with
957 more modern devices, like hard disks, which do not appreciate these
958 reset commands, and can cause your system to hang. So say Y only if
959 you know that one of your older devices needs it; N is the safe

1110 config SCSI_IZIP_SLOW_CTR
1111 bool "ppa/imm option - Assume slow parport control register"
1112 depends on SCSI_PPA || SCSI_IMM
1114 Some parallel ports are known to have excessive delays between
1115 changing the parallel port control register and good data being
1116 available on the parallel port data/status register. This option
1117 forces a small delay (1.0 usec to be exact) after changing the
1118 control register to let things settle out. Enabling this option may
1119 result in a big drop in performance but some very old parallel ports
1120 (found in 386 vintage machines) will not work properly.

1194 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1195 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1196 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI

1208 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1210 When set to 0, the driver will program the chip to only perform
1211 32-bit DMA. When set to 1, the chip will be able to perform DMA
1212 to addresses up to 1TB. When set to 2, the driver supports the
1213 full 64-bit DMA address range, but can only address 16 segments
1214 of 4 GB each. This limits the total addressable range to 64 GB.
1216 Most machines with less than 4GB of memory should use a setting
1217 of 0 for best performance. If your machine has 4GB of memory
1218 or more, you should set this option to 1 (the default).
1220 The still experimental value 2 (64 bit DMA addressing with 16
1221 x 4GB segments limitation) can be used on systems that require
1222 PCI address bits past bit 39 to be set for the addressing of

1299 NCR and commonly used in 345x/35xx/4100 class machines. It always
1300 tries to negotiate sync and uses tag command queueing.
1302 Unless you have an NCR manufactured machine, the chances are that
1303 you do not have this SCSI card, so say N.
1305 config SCSI_NCR53C8XX_DEFAULT_TAGS
1306 int "default tagged command queue depth"
1307 depends on SCSI_ZALON || SCSI_NCR_Q720
1310 "Tagged command queuing" is a feature of SCSI-2 which improves
1311 performance: the host adapter can send several SCSI commands to a
1312 device's queue even if previous commands haven't finished yet.
1313 Because the device is intelligent, it can optimize its operations
1314 (like head positioning) based on its own request queue. Some SCSI
1315 devices don't implement this properly; if you want to disable this
1316 feature, enter 0 or 1 here (it doesn't matter which).
1318 The default value is 8 and should be supported by most hard disks.
1319 This value can be overridden from the boot command line using the
1320 'tags' option as follows (example):
1321 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1322 4, set queue depth to 16 for target 2 and target 3 on controller 0
1323 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1325 The normal answer therefore is to go with the default 8 and to use
1326 a boot command line option for devices that need to use a different
1327 command queue depth.
1329 There is no safe option other than using good SCSI devices.
1331 config SCSI_NCR53C8XX_MAX_TAGS
1332 int "maximum number of queued commands"
1333 depends on SCSI_ZALON || SCSI_NCR_Q720
1336 This option allows you to specify the maximum number of commands
1337 that can be queued to any device, when tagged command queuing is
1338 possible. The default value is 32. Minimum is 2, maximum is 64.
1339 Modern hard disks are able to support 64 tags and even more, but
1340 do not seem to be faster when more than 32 tags are being used.
1342 So, the normal answer here is to go with the default value 32 unless
1343 you are using very large hard disks with large cache (>= 1 MB) that
1344 are able to take advantage of more than 32 tagged commands.
1346 There is no safe option and the default answer is recommended.
1348 config SCSI_NCR53C8XX_SYNC
1349 int "synchronous transfers frequency in MHz"
1350 depends on SCSI_ZALON || SCSI_NCR_Q720
1353 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1354 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1355 are respectively the maximum data transfer rates in mega-transfers
1356 per second for each class. For example, a FAST-20 Wide 16 device is
1357 able to transfer data at 20 million 16 bit packets per second for a
1358 total rate of 40 MB/s.
1360 You may specify 0 if you want to only use asynchronous data
1361 transfers. This is the safest and slowest option. Otherwise, specify
1362 a value between 5 and 80, depending on the capability of your SCSI
1363 controller. The higher the number, the faster the data transfer.
1364 Note that 80 should normally be ok since the driver decreases the
1365 value automatically according to the controller's capabilities.
1367 Your answer to this question is ignored for controllers with NVRAM,
1368 since the driver will get this information from the user set-up. It
1369 also can be overridden using a boot setup option, as follows
1370 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1371 for FAST-20 synchronous data transfer (20 mega-transfers per
1374 The normal answer therefore is not to go with the default but to
1375 select the maximum value 80 allowing the driver to use the maximum
1376 value supported by each controller. If this causes problems with
1377 your SCSI devices, you should come back and decrease the value.
1379 There is no safe option other than using good cabling, right
1380 terminations and SCSI conformant devices.
1382 config SCSI_NCR53C8XX_NO_DISCONNECT
1383 bool "not allow targets to disconnect"
1384 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1386 This option is only provided for safety if you suspect some SCSI
1387 device of yours to not support properly the target-disconnect
1388 feature. In that case, you would say Y here. In general however, to
1389 not allow targets to disconnect is not reasonable if there is more
1390 than 1 device on a SCSI bus. The normal answer therefore is N.

1558 bool "enable tagged command queueing"
1559 depends on SCSI_U14_34F
1561 This is a feature of SCSI-2 which improves performance: the host
1562 adapter can send several SCSI commands to a device's queue even if
1563 previous commands haven't finished yet.

1570 This option enables elevator sorting for all probed SCSI disks and
1571 CD-ROMs. It definitely reduces the average seek distance when doing
1572 random seeks, but this does not necessarily result in a noticeable
1573 performance improvement: your mileage may vary...

1581 This specifies how many SCSI commands can be maximally queued for
1582 each probed SCSI device. You should reduce the default value of 8
1583 only if you have disks with buggy or limited tagged command support.
1584 Minimum is 2 and maximum is 14. This value is also the window size
1585 used by the elevator sorting option above. The effective value used
1586 by the driver for each probed SCSI device is reported at boot time.

1622 This is a host adapter simulator that can simulate multiple hosts
1623 each with multiple dummy SCSI devices (disks). It defaults to one
1624 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1625 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1626 dummy disks are simulated, they share the same kernel RAM for
1627 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more

1649 drives a bus which is entirely internal to the machine (such as the
1650 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1651 operation at up to 10 MB/s. On machines where the SCSI bus
1652 controlled by the MESH can have external devices connected, it is
1653 usually rated at 5 MB/s. 5 is a safe value here unless you know the
