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.

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

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

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

1056 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1057 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1058 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI
1059 controllers; you need to use the Fusion MPT driver for that.

1064 config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
1065 int "DMA addressing mode"
1066 depends on SCSI_SYM53C8XX_2
1069 This option only applies to PCI-SCSI chips that are PCI DAC
1070 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1072 When set to 0, the driver will program the chip to only perform
1073 32-bit DMA. When set to 1, the chip will be able to perform DMA
1074 to addresses up to 1TB. When set to 2, the driver supports the
1075 full 64-bit DMA address range, but can only address 16 segments
1076 of 4 GB each. This limits the total addressable range to 64 GB.
1078 Most machines with less than 4GB of memory should use a setting
1079 of 0 for best performance. If your machine has 4GB of memory
1080 or more, you should set this option to 1 (the default).
1082 The still experimental value 2 (64 bit DMA addressing with 16
1083 x 4GB segments limitation) can be used on systems that require
1084 PCI address bits past bit 39 to be set for the addressing of
1085 memory using PCI DAC cycles.

1092 This is the default value of the command queue depth the
1093 driver will announce to the generic SCSI layer for devices
1094 that support tagged command queueing. This value can be changed
1095 from the boot command line. This is a soft limit that cannot
1096 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1098 config SCSI_SYM53C8XX_MAX_TAGS
1099 int "Maximum number of queued commands"
1100 depends on SCSI_SYM53C8XX_2
1103 This option allows you to specify the maximum number of commands
1104 that can be queued to any device, when tagged command queuing is
1105 possible. The driver supports up to 256 queued commands per device.
1106 This value is used as a compiled-in hard limit.

1149 The Zalon is a GSC/HSC bus interface chip that sits between the
1150 PA-RISC processor and the NCR 53c720 SCSI controller on C100,
1151 C110, J200, J210 and some D, K & R-class machines. It's also

1155 config SCSI_NCR_Q720
1156 tristate "NCR Quad 720 MCA SCSI support"
1157 depends on MCA && SCSI
1158 select SCSI_SPI_ATTRS
1160 This is a driver for the MicroChannel Quad 720 card produced by
1161 NCR and commonly used in 345x/35xx/4100 class machines. It always
1162 tries to negotiate sync and uses tag command queueing.
1164 Unless you have an NCR manufactured machine, the chances are that
1165 you do not have this SCSI card, so say N.
1167 config SCSI_NCR53C8XX_DEFAULT_TAGS
1168 int "default tagged command queue depth"
1169 depends on SCSI_ZALON || SCSI_NCR_Q720
1172 "Tagged command queuing" is a feature of SCSI-2 which improves
1173 performance: the host adapter can send several SCSI commands to a
1174 device's queue even if previous commands haven't finished yet.
1175 Because the device is intelligent, it can optimize its operations
1176 (like head positioning) based on its own request queue. Some SCSI
1177 devices don't implement this properly; if you want to disable this
1178 feature, enter 0 or 1 here (it doesn't matter which).
1180 The default value is 8 and should be supported by most hard disks.
1181 This value can be overridden from the boot command line using the
1182 'tags' option as follows (example):
1183 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1184 4, set queue depth to 16 for target 2 and target 3 on controller 0
1185 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1187 The normal answer therefore is to go with the default 8 and to use
1188 a boot command line option for devices that need to use a different
1189 command queue depth.
1191 There is no safe option other than using good SCSI devices.
1193 config SCSI_NCR53C8XX_MAX_TAGS
1194 int "maximum number of queued commands"
1195 depends on SCSI_ZALON || SCSI_NCR_Q720
1198 This option allows you to specify the maximum number of commands
1199 that can be queued to any device, when tagged command queuing is
1200 possible. The default value is 32. Minimum is 2, maximum is 64.
1201 Modern hard disks are able to support 64 tags and even more, but
1202 do not seem to be faster when more than 32 tags are being used.
1204 So, the normal answer here is to go with the default value 32 unless
1205 you are using very large hard disks with large cache (>= 1 MB) that
1206 are able to take advantage of more than 32 tagged commands.
1208 There is no safe option and the default answer is recommended.
1210 config SCSI_NCR53C8XX_SYNC
1211 int "synchronous transfers frequency in MHz"
1212 depends on SCSI_ZALON || SCSI_NCR_Q720
1215 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1216 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1217 are respectively the maximum data transfer rates in mega-transfers
1218 per second for each class. For example, a FAST-20 Wide 16 device is
1219 able to transfer data at 20 million 16 bit packets per second for a
1220 total rate of 40 MB/s.
1222 You may specify 0 if you want to only use asynchronous data
1223 transfers. This is the safest and slowest option. Otherwise, specify
1224 a value between 5 and 80, depending on the capability of your SCSI
1225 controller. The higher the number, the faster the data transfer.
1226 Note that 80 should normally be ok since the driver decreases the
1227 value automatically according to the controller's capabilities.
1229 Your answer to this question is ignored for controllers with NVRAM,
1230 since the driver will get this information from the user set-up. It
1231 also can be overridden using a boot setup option, as follows
1232 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1233 for FAST-20 synchronous data transfer (20 mega-transfers per
1236 The normal answer therefore is not to go with the default but to
1237 select the maximum value 80 allowing the driver to use the maximum
1238 value supported by each controller. If this causes problems with
1239 your SCSI devices, you should come back and decrease the value.
1241 There is no safe option other than using good cabling, right
1242 terminations and SCSI conformant devices.
1244 config SCSI_NCR53C8XX_NO_DISCONNECT
1245 bool "not allow targets to disconnect"
1246 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1248 This option is only provided for safety if you suspect some SCSI
1249 device of yours to not support properly the target-disconnect
1250 feature. In that case, you would say Y here. In general however, to
1251 not allow targets to disconnect is not reasonable if there is more
1252 than 1 device on a SCSI bus. The normal answer therefore is N.

1341 This is support for the sym53c416 SCSI host adapter, the SCSI
1342 adapter that comes with some HP scanners. This driver requires that
1343 the sym53c416 is configured first using some sort of PnP
1344 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1345 are using isapnp then you need to compile this driver as a module
1346 and then load it using insmod after isapnp has run. The parameters
1347 of the configured card(s) should be passed to the driver. The format

1360 TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants.
1362 This driver works, but is still in experimental status. So better
1363 have a bootable disk and a backup in case of emergency.

1407 This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
1408 The source at <file:drivers/scsi/u14-34f.c> contains some
1409 information about this hardware. If the driver doesn't work out of
1410 the box, you may have to change some settings in

1418 module will be called u14-34f.
1420 config SCSI_U14_34F_TAGGED_QUEUE
1421 bool "enable tagged command queueing"
1422 depends on SCSI_U14_34F
1424 This is a feature of SCSI-2 which improves performance: the host
1425 adapter can send several SCSI commands to a device's queue even if
1426 previous commands haven't finished yet.
1427 This is equivalent to the "u14-34f=tc:y" boot option.
1429 config SCSI_U14_34F_LINKED_COMMANDS
1430 bool "enable elevator sorting"
1431 depends on SCSI_U14_34F
1433 This option enables elevator sorting for all probed SCSI disks and
1434 CD-ROMs. It definitely reduces the average seek distance when doing
1435 random seeks, but this does not necessarily result in a noticeable
1436 performance improvement: your mileage may vary...
1437 This is equivalent to the "u14-34f=lc:y" boot option.
1439 config SCSI_U14_34F_MAX_TAGS
1440 int "maximum number of queued commands"
1441 depends on SCSI_U14_34F
1444 This specifies how many SCSI commands can be maximally queued for
1445 each probed SCSI device. You should reduce the default value of 8
1446 only if you have disks with buggy or limited tagged command support.
1447 Minimum is 2 and maximum is 14. This value is also the window size
1448 used by the elevator sorting option above. The effective value used
1449 by the driver for each probed SCSI device is reported at boot time.
1450 This is equivalent to the "u14-34f=mq:8" boot option.

1478 module will be called nsp32.
1481 tristate "SCSI debugging host simulator"
1485 This is a host adapter simulator that can simulate multiple hosts
1486 each with multiple dummy SCSI devices (disks). It defaults to one
1487 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1488 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1489 dummy disks are simulated, they share the same kernel RAM for
1490 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
1491 information. This driver is primarily of use to those testing the
1492 SCSI and block subsystems. If unsure, say N.

1498 Many Power Macintoshes and clones have a MESH (Macintosh Enhanced
1499 SCSI Hardware) SCSI bus adaptor (the 7200 doesn't, but all of the
1500 other Power Macintoshes do). Say Y to include support for this SCSI

1504 module will be called mesh.
1506 config SCSI_MESH_SYNC_RATE
1507 int "maximum synchronous transfer rate (MB/s) (0 = async)"
1508 depends on SCSI_MESH
1511 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1512 drives a bus which is entirely internal to the machine (such as the
1513 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1514 operation at up to 10 MB/s. On machines where the SCSI bus
1515 controlled by the MESH can have external devices connected, it is
1516 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1517 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1518 to disable synchronous operation.
1520 config SCSI_MESH_RESET_DELAY_MS

1527 depends on PPC32 && PPC_PMAC && SCSI
1529 On Power Macintoshes (and clones) with two SCSI buses, the external
1530 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1531 machines which only have one SCSI bus, such as the 7200, also use
1532 the 53C94. Say Y to include support for the 53C94.

1621 This driver supports both styles of NCR integration into the
1622 system: the TT style (separate DMA), and the Falcon style (via
1623 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1624 in the Hades (without DMA).
1626 config ATARI_SCSI_TOSHIBA_DELAY
1627 bool "Long delays for Toshiba CD-ROMs"
1628 depends on ATARI_SCSI
1630 This option increases the delay after a SCSI arbitration to
1631 accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
1632 use a Toshiba CD-ROM drive; otherwise, the option is not needed and
1633 would impact performance a bit, so say N.
1635 config ATARI_SCSI_RESET_BOOT
1636 bool "Reset SCSI-devices at boottime"
1637 depends on ATARI_SCSI
1639 Reset the devices on your Atari whenever it boots. This makes the
