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

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

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

745 config SCSI_EATA_TAGGED_QUEUE
746 bool "enable tagged command queueing"
749 This is a feature of SCSI-2 which improves performance: the host
750 adapter can send several SCSI commands to a device's queue even if
751 previous commands haven't finished yet.
752 This is equivalent to the "eata=tc:y" boot option.
754 config SCSI_EATA_LINKED_COMMANDS
755 bool "enable elevator sorting"
758 This option enables elevator sorting for all probed SCSI disks and
759 CD-ROMs. It definitely reduces the average seek distance when doing
760 random seeks, but this does not necessarily result in a noticeable
761 performance improvement: your mileage may vary...
762 This is equivalent to the "eata=lc:y" boot option.
764 config SCSI_EATA_MAX_TAGS
765 int "maximum number of queued commands"
769 This specifies how many SCSI commands can be maximally queued for
770 each probed SCSI device. You should reduce the default value of 16
771 only if you have disks with buggy or limited tagged command support.
772 Minimum is 2 and maximum is 62. This value is also the window size
773 used by the elevator sorting option above. The effective value used
774 by the driver for each probed SCSI device is reported at boot time.
775 This is equivalent to the "eata=mq:8" boot option.
778 tristate "EATA-PIO (old DPT PM2001, PM2012A) support"
779 depends on (ISA || EISA || PCI) && SCSI && BROKEN
781 This driver supports all EATA-PIO protocol compliant SCSI Host
782 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
783 host adapters could also use this driver but are discouraged from
784 doing so, since this driver only supports hard disks and lacks
785 numerous features. You might want to have a look at the SCSI-HOWTO,

840 on boards using PIO. Most boards such as the Trantor T130 fit this
841 category, along with a large number of ISA 8bit controllers shipped
842 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
843 you should select the specific driver for that card rather than

1018 allows them to act as expansion buses that can handle up to 64
1021 Some parallel port chipsets are slower than their motherboard, and
1022 so we have to control the state of the chipset's FIFO queue every
1023 now and then to avoid data loss. This will be done if you say Y

1030 depends on SCSI_PPA || SCSI_IMM
1032 Some parallel ports are known to have excessive delays between
1033 changing the parallel port control register and good data being
1034 available on the parallel port data/status register. This option
1035 forces a small delay (1.0 usec to be exact) after changing the
1036 control register to let things settle out. Enabling this option may
1037 result in a big drop in performance but some very old parallel ports
1038 (found in 386 vintage machines) will not work properly.

1113 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1114 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI

1125 This option only applies to PCI-SCSI chips that are PCI DAC
1126 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1128 When set to 0, the driver will program the chip to only perform
1129 32-bit DMA. When set to 1, the chip will be able to perform DMA
1130 to addresses up to 1TB. When set to 2, the driver supports the
1131 full 64-bit DMA address range, but can only address 16 segments
1132 of 4 GB each. This limits the total addressable range to 64 GB.
1134 Most machines with less than 4GB of memory should use a setting
1135 of 0 for best performance. If your machine has 4GB of memory
1136 or more, you should set this option to 1 (the default).
1138 The still experimental value 2 (64 bit DMA addressing with 16
1139 x 4GB segments limitation) can be used on systems that require
1140 PCI address bits past bit 39 to be set for the addressing of

1216 This is a driver for the MicroChannel Quad 720 card produced by
1217 NCR and commonly used in 345x/35xx/4100 class machines. It always
1218 tries to negotiate sync and uses tag command queueing.
1220 Unless you have an NCR manufactured machine, the chances are that
1221 you do not have this SCSI card, so say N.
1223 config SCSI_NCR53C8XX_DEFAULT_TAGS
1224 int "default tagged command queue depth"
1225 depends on SCSI_ZALON || SCSI_NCR_Q720
1228 "Tagged command queuing" is a feature of SCSI-2 which improves
1229 performance: the host adapter can send several SCSI commands to a
1230 device's queue even if previous commands haven't finished yet.
1231 Because the device is intelligent, it can optimize its operations
1232 (like head positioning) based on its own request queue. Some SCSI
1233 devices don't implement this properly; if you want to disable this
1234 feature, enter 0 or 1 here (it doesn't matter which).
1236 The default value is 8 and should be supported by most hard disks.
1237 This value can be overridden from the boot command line using the
1238 'tags' option as follows (example):
1239 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1240 4, set queue depth to 16 for target 2 and target 3 on controller 0
1241 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1243 The normal answer therefore is to go with the default 8 and to use
1244 a boot command line option for devices that need to use a different
1245 command queue depth.
1247 There is no safe option other than using good SCSI devices.
1249 config SCSI_NCR53C8XX_MAX_TAGS
1250 int "maximum number of queued commands"
1251 depends on SCSI_ZALON || SCSI_NCR_Q720
1254 This option allows you to specify the maximum number of commands
1255 that can be queued to any device, when tagged command queuing is
1256 possible. The default value is 32. Minimum is 2, maximum is 64.
1257 Modern hard disks are able to support 64 tags and even more, but
1258 do not seem to be faster when more than 32 tags are being used.
1260 So, the normal answer here is to go with the default value 32 unless
1261 you are using very large hard disks with large cache (>= 1 MB) that
1262 are able to take advantage of more than 32 tagged commands.
1264 There is no safe option and the default answer is recommended.
1266 config SCSI_NCR53C8XX_SYNC
1267 int "synchronous transfers frequency in MHz"
1268 depends on SCSI_ZALON || SCSI_NCR_Q720
1271 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1272 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1273 are respectively the maximum data transfer rates in mega-transfers
1274 per second for each class. For example, a FAST-20 Wide 16 device is
1275 able to transfer data at 20 million 16 bit packets per second for a
1276 total rate of 40 MB/s.
1278 You may specify 0 if you want to only use asynchronous data
1279 transfers. This is the safest and slowest option. Otherwise, specify
1280 a value between 5 and 80, depending on the capability of your SCSI
1281 controller. The higher the number, the faster the data transfer.
1282 Note that 80 should normally be ok since the driver decreases the
1283 value automatically according to the controller's capabilities.
1285 Your answer to this question is ignored for controllers with NVRAM,
1286 since the driver will get this information from the user set-up. It
1287 also can be overridden using a boot setup option, as follows
1288 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1289 for FAST-20 synchronous data transfer (20 mega-transfers per
1292 The normal answer therefore is not to go with the default but to
1293 select the maximum value 80 allowing the driver to use the maximum
1294 value supported by each controller. If this causes problems with
1295 your SCSI devices, you should come back and decrease the value.
1297 There is no safe option other than using good cabling, right
1298 terminations and SCSI conformant devices.

1304 This option is only provided for safety if you suspect some SCSI
1305 device of yours to not support properly the target-disconnect
1306 feature. In that case, you would say Y here. In general however, to
1307 not allow targets to disconnect is not reasonable if there is more
1308 than 1 device on a SCSI bus. The normal answer therefore is N.

1398 the sym53c416 is configured first using some sort of PnP
1399 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1400 are using isapnp then you need to compile this driver as a module

1462 This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
1463 The source at <file:drivers/scsi/u14-34f.c> contains some
1464 information about this hardware. If the driver doesn't work out of

1473 module will be called u14-34f.
1475 config SCSI_U14_34F_TAGGED_QUEUE
1476 bool "enable tagged command queueing"
1477 depends on SCSI_U14_34F
1479 This is a feature of SCSI-2 which improves performance: the host
1480 adapter can send several SCSI commands to a device's queue even if
1481 previous commands haven't finished yet.
1482 This is equivalent to the "u14-34f=tc:y" boot option.
1484 config SCSI_U14_34F_LINKED_COMMANDS
1485 bool "enable elevator sorting"
1486 depends on SCSI_U14_34F
1488 This option enables elevator sorting for all probed SCSI disks and
1489 CD-ROMs. It definitely reduces the average seek distance when doing
1490 random seeks, but this does not necessarily result in a noticeable
1491 performance improvement: your mileage may vary...
1492 This is equivalent to the "u14-34f=lc:y" boot option.
1494 config SCSI_U14_34F_MAX_TAGS
1495 int "maximum number of queued commands"
1496 depends on SCSI_U14_34F
1499 This specifies how many SCSI commands can be maximally queued for
1500 each probed SCSI device. You should reduce the default value of 8
1501 only if you have disks with buggy or limited tagged command support.
1502 Minimum is 2 and maximum is 14. This value is also the window size
1503 used by the elevator sorting option above. The effective value used
1504 by the driver for each probed SCSI device is reported at boot time.
1505 This is equivalent to the "u14-34f=mq:8" boot option.

1536 tristate "SCSI debugging host simulator"
1540 This is a host adapter simulator that can simulate multiple hosts
1541 each with multiple dummy SCSI devices (disks). It defaults to one
1542 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1543 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1544 dummy disks are simulated, they share the same kernel RAM for
1545 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
1546 information. This driver is primarily of use to those testing the
1547 SCSI and block subsystems. If unsure, say N.

1553 Many Power Macintoshes and clones have a MESH (Macintosh Enhanced
1554 SCSI Hardware) SCSI bus adaptor (the 7200 doesn't, but all of the
1555 other Power Macintoshes do). Say Y to include support for this SCSI

1566 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1567 drives a bus which is entirely internal to the machine (such as the
1568 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1569 operation at up to 10 MB/s. On machines where the SCSI bus
1570 controlled by the MESH can have external devices connected, it is
1571 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1572 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1573 to disable synchronous operation.

1582 depends on PPC32 && PPC_PMAC && SCSI
1584 On Power Macintoshes (and clones) with two SCSI buses, the external
1585 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1586 machines which only have one SCSI bus, such as the 7200, also use
1587 the 53C94. Say Y to include support for the 53C94.

1691 bool "Reset SCSI-devices at boottime"
1692 depends on ATARI_SCSI
1694 Reset the devices on your Atari whenever it boots. This makes the
