  22           If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
  23           any other SCSI device under Linux, say Y and make sure that you know
  24           the name of your SCSI host adapter (the card inside your computer
  25           that "speaks" the SCSI protocol, also called SCSI controller),
  26           because you will be asked for it.
  27
  28           You also need to say Y here if you have a device which speaks
  29           the SCSI protocol.  Examples of this include the parallel port
  30           version of the IOMEGA ZIP drive, USB storage devices, Fibre

 119           For more information, you may have a look at the SCSI-HOWTO

 159           CD-ROMs or tapes, say Y here. These won't be supported by the kernel
 160           directly, so you need some additional software which knows how to
 161           talk to these devices using the SCSI protocol:
 162
 163           For scanners, look at SANE (<http://www.sane-project.org/>). For CD
 164           writer software look at Cdrtools
 165           (<http://cdrecord.berlios.de/private/cdrecord.html>)
 166           and for burning a "disk at once": CDRDAO

 168           quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
 169           For other devices, it's possible that you'll have to write the
 170           driver software yourself. Please read the file

 217           This turns on a logging facility that can be used to debug a number
 218           of SCSI related problems.
 219
 220           If you say Y here, no logging output will appear by default, but you
 221           can enable logging by saying Y to "/proc file system support" and

 223
 224           echo <bitmask> > /proc/sys/dev/scsi/logging_level

 227           and logging level for each type of logging selected.
 228
 229           There are a number of logging types and you can find them in the
 230           source at <file:drivers/scsi/scsi_logging.h>. The logging levels
 231           are also described in that file and they determine the verbosity of
 232           the logging for each logging type.
 233
 234           If you say N here, it may be harder to track down some types of SCSI
 235           problems. If you say Y here your kernel will be somewhat larger, but

1167         default "8"
1168         ---help---
1169           "Tagged command queuing" is a feature of SCSI-2 which improves
1170           performance: the host adapter can send several SCSI commands to a
1171           device's queue even if previous commands haven't finished yet.
1172           Because the device is intelligent, it can optimize its operations
1173           (like head positioning) based on its own request queue. Some SCSI
1174           devices don't implement this properly; if you want to disable this
1175           feature, enter 0 or 1 here (it doesn't matter which).
1176
1177           The default value is 8 and should be supported by most hard disks.
1178           This value can be overridden from the boot command line using the
1179           'tags' option as follows (example):
1180           'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1181           4, set queue depth to 16 for target 2 and target 3 on controller 0
1182           and set queue depth to 10 for target 0 / lun 2 on controller 1.
1183
1184           The normal answer therefore is to go with the default 8 and to use
1185           a boot command line option for devices that need to use a different
1186           command queue depth.
1187
1188           There is no safe option other than using good SCSI devices.

1193         default "32"
1194         ---help---
1195           This option allows you to specify the maximum number of commands
1196           that can be queued to any device, when tagged command queuing is
1197           possible. The default value is 32. Minimum is 2, maximum is 64.
1198           Modern hard disks are able to support 64 tags and even more, but
1199           do not seem to be faster when more than 32 tags are being used.
1200
1201           So, the normal answer here is to go with the default value 32 unless
1202           you are using very large hard disks with large cache (>= 1 MB) that
1203           are able to take advantage of more than 32 tagged commands.
1204
1205           There is no safe option and the default answer is recommended.

1210         default "20"
1211         ---help---
1212           The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1213           rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1214           are respectively the maximum data transfer rates in mega-transfers
1215           per second for each class.  For example, a FAST-20 Wide 16 device is
1216           able to transfer data at 20 million 16 bit packets per second for a
1217           total rate of 40 MB/s.
1218
1219           You may specify 0 if you want to only use asynchronous data
1220           transfers. This is the safest and slowest option. Otherwise, specify
1221           a value between 5 and 80, depending on the capability of your SCSI
1222           controller.  The higher the number, the faster the data transfer.
1223           Note that 80 should normally be ok since the driver decreases the
1224           value automatically according to the controller's capabilities.
1225
1226           Your answer to this question is ignored for controllers with NVRAM,
1227           since the driver will get this information from the user set-up.  It
1228           also can be overridden using a boot setup option, as follows
1229           (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1230           for FAST-20 synchronous data transfer (20 mega-transfers per
1231           second).
1232
1233           The normal answer therefore is not to go with the default but to
1234           select the maximum value 80 allowing the driver to use the maximum
1235           value supported by each controller. If this causes problems with
1236           your SCSI devices, you should come back and decrease the value.
1237
1238           There is no safe option other than using good cabling, right
1239           terminations and SCSI conformant devices.

1247           feature. In that case, you would say Y here. In general however, to
1248           not allow targets to disconnect is not reasonable if there is more
1249           than 1 device on a SCSI bus. The normal answer therefore is N.
