  20
  21           You also need to say Y here if you have a device which speaks

 200           If you have a SCSI device that supports more than one LUN (Logical

 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

 212           The error messages regarding your SCSI hardware will be easier to

 220           This turns on a logging facility that can be used to debug a number
 221           of SCSI related problems.
 222
 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
 226
 227           echo "scsi log token [level]" > /proc/scsi/scsi
 228
 229           at boot time after the /proc file system has been mounted.
 230
 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.
 235
 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

 248
 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

 469           WARNING This driver is an older aic7xxx driver and is no longer
 470           under active development.  Adaptec, Inc. is writing a new driver to
 471           take the place of this one, and it is recommended that whenever
 472           possible, people should use the new Adaptec written driver instead
 473           of this one.  This driver will eventually be phased out entirely.
 474
 475           This is support for the various aic7xxx based Adaptec SCSI
 476           controllers. These include the 274x EISA cards; 284x VLB cards;
 477           2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
 478           motherboard based SCSI controllers from Adaptec. It does not support
 479           the AAA-13x RAID controllers from Adaptec, nor will it likely ever
 480           support them. It does not support the 2920 cards from Adaptec that
 481           use the Future Domain SCSI controller chip. For those cards, you
 482           need the "Future Domain 16xx SCSI support" driver.
 483
 484           In general, if the controller is based on an Adaptec SCSI controller
 485           chip from the aic777x series or the aic78xx series, this driver
 486           should work. The only exception is the 7810 which is specifically
 487           not supported (that's the RAID controller chip on the AAA-13x
 488           cards).
 489
 490           Note that the AHA2920 SCSI host adapter is *not* supported by this
 491           driver; choose "Future Domain 16xx SCSI support" instead if you have
 492           one of those.

 810         ---help---
 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.
 826
 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
 833           June 1997).
 834
 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.

 843         ---help---
 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
 853           answer.

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.
1117
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

1210         default "8"
1211         ---help---
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).
1219
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.
1226
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.
1230
1231           There is no safe option other than using good SCSI devices.

1236         default "32"
1237         ---help---
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.
1243
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.

1253         default "20"
1254         ---help---
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.
1261
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.
1268
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
1274           second).
1275
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.
1280
1281           There is no safe option other than using good cabling, right
1282           terminations and SCSI conformant devices.

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.
