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

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

139 drives (and HP Writers). If you have such a drive and get the first
140 session only, try saying Y here; everybody else says N.
143 tristate "SCSI generic support"
146 If you want to use SCSI scanners, synthesizers or CD-writers or just
147 about anything having "SCSI" in its name other than hard disks,
148 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
149 directly, so you need some additional software which knows how to
150 talk to these devices using the SCSI protocol:
152 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
153 writer software look at Cdrtools
154 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
155 and for burning a "disk at once": CDRDAO
156 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
157 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
158 For other devices, it's possible that you'll have to write the
159 driver software yourself. Please read the file
160 <file:Documentation/scsi/scsi-generic.txt> for more information.
162 To compile this driver as a module, choose M here and read

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

188 Enclosures are devices sitting on or in SCSI backplanes that
189 manage devices. If you have a disk cage, the chances are that
190 it has an enclosure device. Selecting this option will just allow
191 certain enclosure conditions to be reported and is not required.
193 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
196 config SCSI_MULTI_LUN
197 bool "Probe all LUNs on each SCSI device"
200 If you have a SCSI device that supports more than one LUN (Logical
201 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
202 can say Y here to force the SCSI driver to probe for multiple LUNs.
203 A SCSI device with multiple LUNs acts logically like multiple SCSI
204 devices. The vast majority of SCSI devices have only one LUN, and
205 so most people can say N here. The max_luns boot/module parameter
206 allows to override this setting.
208 config SCSI_CONSTANTS
209 bool "Verbose SCSI error reporting (kernel size +=12K)"
212 The error messages regarding your SCSI hardware will be easier to
213 understand if you say Y here; it will enlarge your kernel by about
214 12 KB. If in doubt, say Y.
217 bool "SCSI logging facility"
220 This turns on a logging facility that can be used to debug a number
221 of SCSI related problems.
223 If you say Y here, no logging output will appear by default, but you
224 can enable logging by saying Y to "/proc file system support" and
225 "Sysctl support" below and executing the command
227 echo <bitmask> > /proc/sys/dev/scsi/logging_level
229 where <bitmask> is a four byte value representing the logging type
230 and logging level for each type of logging selected.
232 There are a number of logging types and you can find them in the
233 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
234 are also described in that file and they determine the verbosity of
235 the logging for each logging type.
237 If you say N here, it may be harder to track down some types of SCSI
238 problems. If you say Y here your kernel will be somewhat larger, but
239 there should be no noticeable performance impact as long as you have
242 config SCSI_SCAN_ASYNC
243 bool "Asynchronous SCSI scanning"
246 The SCSI subsystem can probe for devices while the rest of the
247 system continues booting, and even probe devices on different
248 busses in parallel, leading to a significant speed-up.
250 If you have built SCSI as modules, enabling this option can
251 be a problem as the devices may not have been found by the
252 time your system expects them to have been. You can load the
253 scsi_wait_scan module to ensure that all scans have completed.
254 If you build your SCSI drivers into the kernel, then everything
255 will work fine if you say Y here.
257 You can override this choice by specifying "scsi_mod.scan=sync"
258 or async on the kernel's command line.

340 The iSCSI Driver provides a host with the ability to access storage

342 SCSI requests and responses over a TCP/IP network between the host
343 (the "initiator") and "targets". Architecturally, the iSCSI driver

701 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
702 host adapters could also use this driver but are discouraged from

762 This is a driver for the old NCR 53c80 series of SCSI controllers
763 on boards using PIO. Most boards such as the Trantor T130 fit this
764 category, along with a large number of ISA 8bit controllers shipped
765 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
766 you should select the specific driver for that card rather than
767 generic 5380 support.
769 It is explained in section 3.8 of the SCSI-HOWTO, available from
770 <http://www.tldp.org/docs.html#howto>. If it doesn't work out

796 This enables certain optimizations for the NCR53c400 SCSI cards.
797 You might as well try it out. Note that this driver will only probe
798 for the Trantor T130B in its default configuration; you might have
799 to pass a command line option to the kernel at boot time if it does
800 not detect your card. See the file
801 <file:Documentation/scsi/g_NCR5380.txt> for details.
804 tristate "IBMMCA SCSI support"
805 depends on MCA && SCSI
807 This is support for the IBM SCSI adapter found in many of the PS/2
808 series computers. These machines have an MCA bus, so you need to
809 answer Y to "MCA support" as well and read
810 <file:Documentation/mca.txt>.
812 If the adapter isn't found during boot (a common problem for models
813 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
814 option, where <pun> is the id of the SCSI subsystem (usually 7, but
815 if that doesn't work check your reference diskette). Owners of
816 model 95 with a LED-matrix-display can in addition activate some
817 activity info like under OS/2, but more informative, by setting
818 'ibmmcascsi=display' as an additional kernel parameter. Try "man
819 bootparam" or see the documentation of your boot loader about how to
820 pass options to the kernel.

823 module will be called ibmmca.
825 config IBMMCA_SCSI_ORDER_STANDARD
826 bool "Standard SCSI-order"
827 depends on SCSI_IBMMCA
829 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
830 are assigned to the drive letters, starting with the lowest SCSI-id
831 (physical number -- pun) to be drive C:, as seen from DOS and
832 similar operating systems. When looking into papers describing the
833 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
834 The SCSI-standard follows a hardware-hierarchy which says that id 7
835 has the highest priority and id 0 the lowest. Therefore, the host
836 adapters are still today everywhere placed as SCSI-id 7 by default.
837 In the SCSI-standard, the drive letters express the priority of the
838 disk. C: should be the hard disk, or a partition on it, with the
839 highest priority. This must therefore be the disk with the highest
840 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
841 original definition of the SCSI-standard as also industrial- and
842 process-control-machines, like VME-CPUs running under realtime-OSes
843 (e.g. LynxOS, OS9) do.
845 If you like to run Linux on your MCA-machine with the same
846 assignment of hard disks as seen from e.g. DOS or OS/2 on your
847 machine, which is in addition conformant to the SCSI-standard, you
848 must say Y here. This is also necessary for MCA-Linux users who want
849 to keep downward compatibility to older releases of the
850 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
853 If you like to have the lowest SCSI-id assigned as drive C:, as
854 modern SCSI-BIOSes do, which does not conform to the standard, but

856 here. If unsure, say Y.
858 config IBMMCA_SCSI_DEV_RESET
859 bool "Reset SCSI-devices at boottime"

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

1025 Some parallel ports are known to have excessive delays between
1026 changing the parallel port control register and good data being
1027 available on the parallel port data/status register. This option
1028 forces a small delay (1.0 usec to be exact) after changing the

1129 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1131 When set to 0, the driver will program the chip to only perform
1132 32-bit DMA. When set to 1, the chip will be able to perform DMA
1133 to addresses up to 1TB. When set to 2, the driver supports the
1134 full 64-bit DMA address range, but can only address 16 segments
1135 of 4 GB each. This limits the total addressable range to 64 GB.
1137 Most machines with less than 4GB of memory should use a setting
1138 of 0 for best performance. If your machine has 4GB of memory
1139 or more, you should set this option to 1 (the default).
1141 The still experimental value 2 (64 bit DMA addressing with 16

1227 int "default tagged command queue depth"
1228 depends on SCSI_ZALON || SCSI_NCR_Q720
1231 "Tagged command queuing" is a feature of SCSI-2 which improves
1232 performance: the host adapter can send several SCSI commands to a
1233 device's queue even if previous commands haven't finished yet.
1234 Because the device is intelligent, it can optimize its operations
1235 (like head positioning) based on its own request queue. Some SCSI
1236 devices don't implement this properly; if you want to disable this
1237 feature, enter 0 or 1 here (it doesn't matter which).
1239 The default value is 8 and should be supported by most hard disks.
1240 This value can be overridden from the boot command line using the
1241 'tags' option as follows (example):
1242 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1243 4, set queue depth to 16 for target 2 and target 3 on controller 0
1244 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1246 The normal answer therefore is to go with the default 8 and to use
1247 a boot command line option for devices that need to use a different
1248 command queue depth.
1250 There is no safe option other than using good SCSI devices.
1252 config SCSI_NCR53C8XX_MAX_TAGS
1253 int "maximum number of queued commands"

1257 This option allows you to specify the maximum number of commands
1258 that can be queued to any device, when tagged command queuing is
1259 possible. The default value is 32. Minimum is 2, maximum is 64.
1260 Modern hard disks are able to support 64 tags and even more, but
1261 do not seem to be faster when more than 32 tags are being used.
1263 So, the normal answer here is to go with the default value 32 unless
1264 you are using very large hard disks with large cache (>= 1 MB) that
1265 are able to take advantage of more than 32 tagged commands.
1267 There is no safe option and the default answer is recommended.

1274 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1275 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1276 are respectively the maximum data transfer rates in mega-transfers
1277 per second for each class. For example, a FAST-20 Wide 16 device is
1278 able to transfer data at 20 million 16 bit packets per second for a
1279 total rate of 40 MB/s.
1281 You may specify 0 if you want to only use asynchronous data
1282 transfers. This is the safest and slowest option. Otherwise, specify
1283 a value between 5 and 80, depending on the capability of your SCSI
1284 controller. The higher the number, the faster the data transfer.
1285 Note that 80 should normally be ok since the driver decreases the
1286 value automatically according to the controller's capabilities.
1288 Your answer to this question is ignored for controllers with NVRAM,
1289 since the driver will get this information from the user set-up. It
1290 also can be overridden using a boot setup option, as follows
1291 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1292 for FAST-20 synchronous data transfer (20 mega-transfers per
1295 The normal answer therefore is not to go with the default but to
1296 select the maximum value 80 allowing the driver to use the maximum
1297 value supported by each controller. If this causes problems with
1298 your SCSI devices, you should come back and decrease the value.
1300 There is no safe option other than using good cabling, right
1301 terminations and SCSI conformant devices.

1304 bool "not allow targets to disconnect"
1305 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1307 This option is only provided for safety if you suspect some SCSI
1308 device of yours to not support properly the target-disconnect
1309 feature. In that case, you would say Y here. In general however, to
1310 not allow targets to disconnect is not reasonable if there is more
1311 than 1 device on a SCSI bus. The normal answer therefore is N.

1401 the sym53c416 is configured first using some sort of PnP
1402 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1403 are using isapnp then you need to compile this driver as a module

1478 config SCSI_U14_34F_TAGGED_QUEUE
1479 bool "enable tagged command queueing"
1480 depends on SCSI_U14_34F
1482 This is a feature of SCSI-2 which improves performance: the host
1483 adapter can send several SCSI commands to a device's queue even if
1484 previous commands haven't finished yet.
1485 This is equivalent to the "u14-34f=tc:y" boot option.
1487 config SCSI_U14_34F_LINKED_COMMANDS
1488 bool "enable elevator sorting"
1489 depends on SCSI_U14_34F
1491 This option enables elevator sorting for all probed SCSI disks and
1492 CD-ROMs. It definitely reduces the average seek distance when doing
1493 random seeks, but this does not necessarily result in a noticeable
1494 performance improvement: your mileage may vary...
1495 This is equivalent to the "u14-34f=lc:y" boot option.
1497 config SCSI_U14_34F_MAX_TAGS
1498 int "maximum number of queued commands"
1499 depends on SCSI_U14_34F
1502 This specifies how many SCSI commands can be maximally queued for
1503 each probed SCSI device. You should reduce the default value of 8
1504 only if you have disks with buggy or limited tagged command support.
1505 Minimum is 2 and maximum is 14. This value is also the window size
1506 used by the elevator sorting option above. The effective value used
1507 by the driver for each probed SCSI device is reported at boot time.
1508 This is equivalent to the "u14-34f=mq:8" boot option.

1539 tristate "SCSI debugging host simulator"
1543 This is a host adapter simulator that can simulate multiple hosts
1544 each with multiple dummy SCSI devices (disks). It defaults to one
1545 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1546 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1547 dummy disks are simulated, they share the same kernel RAM for
1548 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1549 information. This driver is primarily of use to those testing the
1550 SCSI and block subsystems. If unsure, say N.

1569 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1570 drives a bus which is entirely internal to the machine (such as the
1571 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1572 operation at up to 10 MB/s. On machines where the SCSI bus
1573 controlled by the MESH can have external devices connected, it is
1574 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1575 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1576 to disable synchronous operation.

1587 On Power Macintoshes (and clones) with two SCSI buses, the external
1588 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1589 machines which only have one SCSI bus, such as the 7200, also use
