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, FireWire storage and the IDE-SCSI emulation driver.

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 and ide-scsi, you may be able to drive the USB-x0 and DI-x0 drives
106 as well. 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

168 tristate "SCSI media changer support"
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

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 "scsi log token [level]" > /proc/scsi/scsi
229 at boot time after the /proc file system has been mounted.
231 There are a number of things that can be used for 'token' (you can
232 find them in the source: <file:drivers/scsi/scsi.c>), and this
233 allows you to select the types of information you want, and the
234 level allows you to select the level of verbosity.
236 If you say N here, it may be harder to track down some types of SCSI
237 problems. If you say Y here your kernel will be somewhat larger, but
238 there should be no noticeable performance impact as long as you have
241 config SCSI_SCAN_ASYNC
242 bool "Asynchronous SCSI scanning"
245 The SCSI subsystem can probe for devices while the rest of the
246 system continues booting, and even probe devices on different
247 busses in parallel, leading to a significant speed-up.
249 If you have built SCSI as modules, enabling this option can
250 be a problem as the devices may not have been found by the
251 time your system expects them to have been. You can load the
252 scsi_wait_scan module to ensure that all scans have completed.
253 If you build your SCSI drivers into the kernel, then everything
254 will work fine if you say Y here.
256 You can override this choice by specifying "scsi_mod.scan=sync"
257 or async on the kernel's command line.

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

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

716 This is support for Future Domain MCS 600/700 MCA SCSI adapters.
717 Some PS/2 computers are equipped with IBM Fast SCSI Adapter/A which
718 is identical to the MCS 700 and hence also supported by this driver.

744 This is a driver for the old NCR 53c80 series of SCSI controllers
745 on boards using PIO. Most boards such as the Trantor T130 fit this
746 category, along with a large number of ISA 8bit controllers shipped
747 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
748 you should select the specific driver for that card rather than
749 generic 5380 support.
751 It is explained in section 3.8 of the SCSI-HOWTO, available from

778 This enables certain optimizations for the NCR53c400 SCSI cards.
779 You might as well try it out. Note that this driver will only probe
780 for the Trantor T130B in its default configuration; you might have
781 to pass a command line option to the kernel at boot time if it does
782 not detect your card. See the file
783 <file:Documentation/scsi/g_NCR5380.txt> for details.
786 tristate "IBMMCA SCSI support"
787 depends on MCA && SCSI
789 This is support for the IBM SCSI adapter found in many of the PS/2
790 series computers. These machines have an MCA bus, so you need to
791 answer Y to "MCA support" as well and read
792 <file:Documentation/mca.txt>.
794 If the adapter isn't found during boot (a common problem for models
795 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
796 option, where <pun> is the id of the SCSI subsystem (usually 7, but
797 if that doesn't work check your reference diskette). Owners of
798 model 95 with a LED-matrix-display can in addition activate some
799 activity info like under OS/2, but more informative, by setting
800 'ibmmcascsi=display' as an additional kernel parameter. Try "man
801 bootparam" or see the documentation of your boot loader about how to
802 pass options to the kernel.

805 module will be called ibmmca.
807 config IBMMCA_SCSI_ORDER_STANDARD
808 bool "Standard SCSI-order"
809 depends on SCSI_IBMMCA
811 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
812 are assigned to the drive letters, starting with the lowest SCSI-id
813 (physical number -- pun) to be drive C:, as seen from DOS and
814 similar operating systems. When looking into papers describing the
815 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
816 The SCSI-standard follows a hardware-hierarchy which says that id 7
817 has the highest priority and id 0 the lowest. Therefore, the host
818 adapters are still today everywhere placed as SCSI-id 7 by default.
819 In the SCSI-standard, the drive letters express the priority of the
820 disk. C: should be the hard disk, or a partition on it, with the
821 highest priority. This must therefore be the disk with the highest
822 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
823 original definition of the SCSI-standard as also industrial- and
824 process-control-machines, like VME-CPUs running under realtime-OSes
825 (e.g. LynxOS, OS9) do.
827 If you like to run Linux on your MCA-machine with the same
828 assignment of hard disks as seen from e.g. DOS or OS/2 on your
829 machine, which is in addition conformant to the SCSI-standard, you
830 must say Y here. This is also necessary for MCA-Linux users who want
831 to keep downward compatibility to older releases of the
832 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
835 If you like to have the lowest SCSI-id assigned as drive C:, as
836 modern SCSI-BIOSes do, which does not conform to the standard, but
837 is widespread and common in the PC-world of today, you must say N
838 here. If unsure, say Y.
840 config IBMMCA_SCSI_DEV_RESET
841 bool "Reset SCSI-devices at boottime"
842 depends on SCSI_IBMMCA
844 By default, SCSI-devices are reset when the machine is powered on.
845 However, some devices exist, like special-control-devices,
846 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
847 not reset when switched on. If you say Y here, each device connected
848 to your SCSI-bus will be issued a reset-command after it has been
849 probed, while the kernel is booting. This may cause problems with
850 more modern devices, like hard disks, which do not appreciate these
851 reset commands, and can cause your system to hang. So say Y only if
852 you know that one of your older devices needs it; N is the safe

1006 Some parallel ports are known to have excessive delays between
1007 changing the parallel port control register and good data being
1008 available on the parallel port data/status register. This option
1009 forces a small delay (1.0 usec to be exact) after changing the
1010 control register to let things settle out. Enabling this option may
1011 result in a big drop in performance but some very old parallel ports

1097 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1098 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI

1110 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1112 When set to 0, the driver will program the chip to only perform
1113 32-bit DMA. When set to 1, the chip will be able to perform DMA
1114 to addresses up to 1TB. When set to 2, the driver supports the
1115 full 64-bit DMA address range, but can only address 16 segments
1116 of 4 GB each. This limits the total addressable range to 64 GB.
1118 Most machines with less than 4GB of memory should use a setting
1119 of 0 for best performance. If your machine has 4GB of memory
1120 or more, you should set this option to 1 (the default).
1122 The still experimental value 2 (64 bit DMA addressing with 16
1123 x 4GB segments limitation) can be used on systems that require

1208 int "default tagged command queue depth"
1209 depends on SCSI_ZALON || SCSI_NCR_Q720
1212 "Tagged command queuing" is a feature of SCSI-2 which improves
1213 performance: the host adapter can send several SCSI commands to a
1214 device's queue even if previous commands haven't finished yet.
1215 Because the device is intelligent, it can optimize its operations
1216 (like head positioning) based on its own request queue. Some SCSI
1217 devices don't implement this properly; if you want to disable this
1218 feature, enter 0 or 1 here (it doesn't matter which).
1220 The default value is 8 and should be supported by most hard disks.
1221 This value can be overridden from the boot command line using the
1222 'tags' option as follows (example):
1223 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1224 4, set queue depth to 16 for target 2 and target 3 on controller 0
1225 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1227 The normal answer therefore is to go with the default 8 and to use
1228 a boot command line option for devices that need to use a different
1229 command queue depth.
1231 There is no safe option other than using good SCSI devices.
1233 config SCSI_NCR53C8XX_MAX_TAGS
1234 int "maximum number of queued commands"
1235 depends on SCSI_ZALON || SCSI_NCR_Q720
1238 This option allows you to specify the maximum number of commands
1239 that can be queued to any device, when tagged command queuing is
1240 possible. The default value is 32. Minimum is 2, maximum is 64.
1241 Modern hard disks are able to support 64 tags and even more, but
1242 do not seem to be faster when more than 32 tags are being used.
1244 So, the normal answer here is to go with the default value 32 unless
1245 you are using very large hard disks with large cache (>= 1 MB) that
1246 are able to take advantage of more than 32 tagged commands.
1248 There is no safe option and the default answer is recommended.

1255 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1256 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1257 are respectively the maximum data transfer rates in mega-transfers
1258 per second for each class. For example, a FAST-20 Wide 16 device is
1259 able to transfer data at 20 million 16 bit packets per second for a
1260 total rate of 40 MB/s.
1262 You may specify 0 if you want to only use asynchronous data
1263 transfers. This is the safest and slowest option. Otherwise, specify
1264 a value between 5 and 80, depending on the capability of your SCSI
1265 controller. The higher the number, the faster the data transfer.
1266 Note that 80 should normally be ok since the driver decreases the
1267 value automatically according to the controller's capabilities.
1269 Your answer to this question is ignored for controllers with NVRAM,
1270 since the driver will get this information from the user set-up. It
1271 also can be overridden using a boot setup option, as follows
1272 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1273 for FAST-20 synchronous data transfer (20 mega-transfers per
1276 The normal answer therefore is not to go with the default but to
1277 select the maximum value 80 allowing the driver to use the maximum
1278 value supported by each controller. If this causes problems with
1279 your SCSI devices, you should come back and decrease the value.
1281 There is no safe option other than using good cabling, right
1282 terminations and SCSI conformant devices.

1285 bool "not allow targets to disconnect"
1286 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1288 This option is only provided for safety if you suspect some SCSI
1289 device of yours to not support properly the target-disconnect
1290 feature. In that case, you would say Y here. In general however, to
1291 not allow targets to disconnect is not reasonable if there is more
1292 than 1 device on a SCSI bus. The normal answer therefore is N.

1383 the sym53c416 is configured first using some sort of PnP
1384 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1385 are using isapnp then you need to compile this driver as a module

1460 config SCSI_U14_34F_TAGGED_QUEUE
1461 bool "enable tagged command queueing"
1462 depends on SCSI_U14_34F
1464 This is a feature of SCSI-2 which improves performance: the host
1465 adapter can send several SCSI commands to a device's queue even if
1466 previous commands haven't finished yet.
1467 This is equivalent to the "u14-34f=tc:y" boot option.
1469 config SCSI_U14_34F_LINKED_COMMANDS
1470 bool "enable elevator sorting"
1471 depends on SCSI_U14_34F
1473 This option enables elevator sorting for all probed SCSI disks and
1474 CD-ROMs. It definitely reduces the average seek distance when doing
1475 random seeks, but this does not necessarily result in a noticeable
1476 performance improvement: your mileage may vary...
1477 This is equivalent to the "u14-34f=lc:y" boot option.
1479 config SCSI_U14_34F_MAX_TAGS
1480 int "maximum number of queued commands"
1481 depends on SCSI_U14_34F
1484 This specifies how many SCSI commands can be maximally queued for
1485 each probed SCSI device. You should reduce the default value of 8
1486 only if you have disks with buggy or limited tagged command support.
1487 Minimum is 2 and maximum is 14. This value is also the window size
1488 used by the elevator sorting option above. The effective value used
1489 by the driver for each probed SCSI device is reported at boot time.

1521 tristate "SCSI debugging host simulator"
1524 This is a host adapter simulator that can simulate multiple hosts
1525 each with multiple dummy SCSI devices (disks). It defaults to one
1526 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1527 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1528 dummy disks are simulated, they share the same kernel RAM for
1529 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1530 information. This driver is primarily of use to those testing the
1531 SCSI and block subsystems. If unsure, say N.

1550 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1551 drives a bus which is entirely internal to the machine (such as the
1552 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1553 operation at up to 10 MB/s. On machines where the SCSI bus
1554 controlled by the MESH can have external devices connected, it is
1555 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1556 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1557 to disable synchronous operation.
