21 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
22 any other SCSI device under Linux, say Y and make sure that you know
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.
32 To compile this driver as a module, choose M here and read
33 <file:Documentation/scsi/scsi.txt>.
34 The module will be called scsi_mod.
36 However, do not compile this as a module if your root file system
37 (the one containing the directory /) is located on a SCSI device.

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
119 <http://sourceforge.net/projects/osst/>
120 Please also have a look at the standard st docu, as most of it
121 applies to osst as well.
123 To compile this driver as a module, choose M here and read
124 <file:Documentation/scsi/scsi.txt>. The module will be called osst.
127 tristate "SCSI CDROM support"
130 If you want to use a CD or DVD drive attached to your computer
131 by SCSI, FireWire, USB or ATAPI, say Y and read the SCSI-HOWTO
132 and the CDROM-HOWTO at <http://www.tldp.org/docs.html#howto>.
134 Make sure to say Y or M to "ISO 9660 CD-ROM file system support".

141 bool "Enable vendor-specific extensions (for SCSI CDROM)"
142 depends on BLK_DEV_SR
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 overridden 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 explicitly 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 Note that this setting also affects whether resuming from
267 system suspend will be performed asynchronously.

345 The iSCSI Driver provides a host with the ability to access storage
346 through an IP network. The driver uses the iSCSI protocol to transport
347 SCSI requests and responses over a TCP/IP network between the host
348 (the "initiator") and "targets". Architecturally, the iSCSI driver
349 combines with the host's TCP/IP stack, network drivers, and Network
350 Interface Card (NIC) to provide the same functions as a SCSI or a

730 host adapters could also use this driver but are discouraged from
731 doing so, since this driver only supports hard disks and lacks
732 numerous features. You might want to have a look at the SCSI-HOWTO,

787 on boards using PIO. Most boards such as the Trantor T130 fit this
788 category, along with a large number of ISA 8bit controllers shipped
789 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191

964 EPP (Enhanced Parallel Port) is a standard for parallel ports which
965 allows them to act as expansion buses that can handle up to 64
968 Some parallel port chipsets are slower than their motherboard, and
969 so we have to control the state of the chipset's FIFO queue every
970 now and then to avoid data loss. This will be done if you say Y

975 config SCSI_IZIP_SLOW_CTR
976 bool "ppa/imm option - Assume slow parport control register"
977 depends on SCSI_PPA || SCSI_IMM
979 Some parallel ports are known to have excessive delays between
980 changing the parallel port control register and good data being
981 available on the parallel port data/status register. This option
982 forces a small delay (1.0 usec to be exact) after changing the
983 control register to let things settle out. Enabling this option may
984 result in a big drop in performance but some very old parallel ports
985 (found in 386 vintage machines) will not work properly.

1058 This driver supports the whole NCR53C8XX/SYM53C8XX family of
1059 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1060 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1061 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI
1062 controllers; you need to use the Fusion MPT driver for that.

1067 config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
1068 int "DMA addressing mode"
1069 depends on SCSI_SYM53C8XX_2
1072 This option only applies to PCI-SCSI chips that are PCI DAC
1073 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1075 When set to 0, the driver will program the chip to only perform
1076 32-bit DMA. When set to 1, the chip will be able to perform DMA
1077 to addresses up to 1TB. When set to 2, the driver supports the
1078 full 64-bit DMA address range, but can only address 16 segments
1079 of 4 GB each. This limits the total addressable range to 64 GB.
1081 Most machines with less than 4GB of memory should use a setting
1082 of 0 for best performance. If your machine has 4GB of memory
1083 or more, you should set this option to 1 (the default).
1085 The still experimental value 2 (64 bit DMA addressing with 16
1086 x 4GB segments limitation) can be used on systems that require
1087 PCI address bits past bit 39 to be set for the addressing of
1088 memory using PCI DAC cycles.

1095 This is the default value of the command queue depth the
1096 driver will announce to the generic SCSI layer for devices
1097 that support tagged command queueing. This value can be changed
1098 from the boot command line. This is a soft limit that cannot
1099 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1101 config SCSI_SYM53C8XX_MAX_TAGS
1102 int "Maximum number of queued commands"
1103 depends on SCSI_SYM53C8XX_2
1106 This option allows you to specify the maximum number of commands
1107 that can be queued to any device, when tagged command queuing is
1108 possible. The driver supports up to 256 queued commands per device.
1109 This value is used as a compiled-in hard limit.
1111 config SCSI_SYM53C8XX_MMIO
1112 bool "Use memory mapped IO"
1113 depends on SCSI_SYM53C8XX_2
1116 Memory mapped IO is faster than Port IO. Most people should

1118 to answer N here, please report the problem to the maintainer.
1121 tristate "IBM Power Linux RAID adapter support"
1122 depends on PCI && SCSI && ATA
1125 This driver supports the IBM Power Linux family RAID adapters.
1126 This includes IBM pSeries 5712, 5703, 5709, and 570A, as well
1127 as IBM iSeries 5702, 5703, 5709, and 570A.

1136 dumped using /sys/bus/class/scsi_host/hostXX/trace.
1138 config SCSI_IPR_DUMP
1139 bool "enable adapter dump support"
1143 If you say Y here, the driver will support adapter crash dump.
1144 If you enable this support, the iprdump daemon can be used
1145 to capture adapter failure analysis information.

1152 The Zalon is a GSC/HSC bus interface chip that sits between the
1153 PA-RISC processor and the NCR 53c720 SCSI controller on C100,
1154 C110, J200, J210 and some D, K & R-class machines. It's also
1155 used on the add-in Bluefish, Barracuda & Shrike SCSI cards.

1158 config SCSI_NCR_Q720
1159 tristate "NCR Quad 720 MCA SCSI support"
1160 depends on MCA && SCSI
1161 select SCSI_SPI_ATTRS
1163 This is a driver for the MicroChannel Quad 720 card produced by
1164 NCR and commonly used in 345x/35xx/4100 class machines. It always
1165 tries to negotiate sync and uses tag command queueing.
1167 Unless you have an NCR manufactured machine, the chances are that
1168 you do not have this SCSI card, so say N.
1170 config SCSI_NCR53C8XX_DEFAULT_TAGS
1171 int "default tagged command queue depth"
1172 depends on SCSI_ZALON || SCSI_NCR_Q720
1175 "Tagged command queuing" is a feature of SCSI-2 which improves
1176 performance: the host adapter can send several SCSI commands to a
1177 device's queue even if previous commands haven't finished yet.
1178 Because the device is intelligent, it can optimize its operations
1179 (like head positioning) based on its own request queue. Some SCSI
1180 devices don't implement this properly; if you want to disable this
1181 feature, enter 0 or 1 here (it doesn't matter which).
1183 The default value is 8 and should be supported by most hard disks.
1184 This value can be overridden from the boot command line using the
1185 'tags' option as follows (example):
1186 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1187 4, set queue depth to 16 for target 2 and target 3 on controller 0
1188 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1190 The normal answer therefore is to go with the default 8 and to use
1191 a boot command line option for devices that need to use a different
1192 command queue depth.
1194 There is no safe option other than using good SCSI devices.
1196 config SCSI_NCR53C8XX_MAX_TAGS
1197 int "maximum number of queued commands"
1198 depends on SCSI_ZALON || SCSI_NCR_Q720
1201 This option allows you to specify the maximum number of commands
1202 that can be queued to any device, when tagged command queuing is
1203 possible. The default value is 32. Minimum is 2, maximum is 64.
1204 Modern hard disks are able to support 64 tags and even more, but
1205 do not seem to be faster when more than 32 tags are being used.
1207 So, the normal answer here is to go with the default value 32 unless
1208 you are using very large hard disks with large cache (>= 1 MB) that
1209 are able to take advantage of more than 32 tagged commands.
1211 There is no safe option and the default answer is recommended.
1213 config SCSI_NCR53C8XX_SYNC
1214 int "synchronous transfers frequency in MHz"
1215 depends on SCSI_ZALON || SCSI_NCR_Q720
1218 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1219 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1220 are respectively the maximum data transfer rates in mega-transfers
1221 per second for each class. For example, a FAST-20 Wide 16 device is
1222 able to transfer data at 20 million 16 bit packets per second for a
1223 total rate of 40 MB/s.
1225 You may specify 0 if you want to only use asynchronous data
1226 transfers. This is the safest and slowest option. Otherwise, specify
1227 a value between 5 and 80, depending on the capability of your SCSI
1228 controller. The higher the number, the faster the data transfer.
1229 Note that 80 should normally be ok since the driver decreases the
1230 value automatically according to the controller's capabilities.
1232 Your answer to this question is ignored for controllers with NVRAM,
1233 since the driver will get this information from the user set-up. It
1234 also can be overridden using a boot setup option, as follows
1235 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1236 for FAST-20 synchronous data transfer (20 mega-transfers per
1239 The normal answer therefore is not to go with the default but to
1240 select the maximum value 80 allowing the driver to use the maximum
1241 value supported by each controller. If this causes problems with
1242 your SCSI devices, you should come back and decrease the value.
1244 There is no safe option other than using good cabling, right
1245 terminations and SCSI conformant devices.
1247 config SCSI_NCR53C8XX_NO_DISCONNECT
1248 bool "not allow targets to disconnect"
1249 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1251 This option is only provided for safety if you suspect some SCSI
1252 device of yours to not support properly the target-disconnect
1253 feature. In that case, you would say Y here. In general however, to
1254 not allow targets to disconnect is not reasonable if there is more
1255 than 1 device on a SCSI bus. The normal answer therefore is N.

1346 the sym53c416 is configured first using some sort of PnP
1347 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1348 are using isapnp then you need to compile this driver as a module
1349 and then load it using insmod after isapnp has run. The parameters
1350 of the configured card(s) should be passed to the driver. The format

1423 config SCSI_U14_34F_TAGGED_QUEUE
1424 bool "enable tagged command queueing"
1425 depends on SCSI_U14_34F
1427 This is a feature of SCSI-2 which improves performance: the host
1428 adapter can send several SCSI commands to a device's queue even if
1429 previous commands haven't finished yet.
1430 This is equivalent to the "u14-34f=tc:y" boot option.
1432 config SCSI_U14_34F_LINKED_COMMANDS
1433 bool "enable elevator sorting"
1434 depends on SCSI_U14_34F
1436 This option enables elevator sorting for all probed SCSI disks and
1437 CD-ROMs. It definitely reduces the average seek distance when doing
1438 random seeks, but this does not necessarily result in a noticeable
1439 performance improvement: your mileage may vary...
1440 This is equivalent to the "u14-34f=lc:y" boot option.
1442 config SCSI_U14_34F_MAX_TAGS
1443 int "maximum number of queued commands"
1444 depends on SCSI_U14_34F
1447 This specifies how many SCSI commands can be maximally queued for
1448 each probed SCSI device. You should reduce the default value of 8
1449 only if you have disks with buggy or limited tagged command support.
1450 Minimum is 2 and maximum is 14. This value is also the window size
1451 used by the elevator sorting option above. The effective value used
1452 by the driver for each probed SCSI device is reported at boot time.

1484 tristate "SCSI debugging host simulator"
1488 This is a host adapter simulator that can simulate multiple hosts
1489 each with multiple dummy SCSI devices (disks). It defaults to one
1490 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1491 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1492 dummy disks are simulated, they share the same kernel RAM for
1493 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
1494 information. This driver is primarily of use to those testing the
1495 SCSI and block subsystems. If unsure, say N.

1511 depends on SCSI_MESH
1514 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1515 drives a bus which is entirely internal to the machine (such as the
1516 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1517 operation at up to 10 MB/s. On machines where the SCSI bus
1518 controlled by the MESH can have external devices connected, it is
1519 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1520 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1521 to disable synchronous operation.

1530 depends on PPC32 && PPC_PMAC && SCSI
1532 On Power Macintoshes (and clones) with two SCSI buses, the external
1533 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1534 machines which only have one SCSI bus, such as the 7200, also use
1535 the 53C94. Say Y to include support for the 53C94.

1624 This driver supports both styles of NCR integration into the
1625 system: the TT style (separate DMA), and the Falcon style (via
1626 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1627 in the Hades (without DMA).

1633 This option increases the delay after a SCSI arbitration to
1634 accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
1635 use a Toshiba CD-ROM drive; otherwise, the option is not needed and
1636 would impact performance a bit, so say N.
1638 config ATARI_SCSI_RESET_BOOT
1639 bool "Reset SCSI-devices at boottime"
1640 depends on ATARI_SCSI
1642 Reset the devices on your Atari whenever it boots. This makes the
