26 the name of your SCSI host adapter (the card inside your computer
27 that "speaks" the SCSI protocol, also called SCSI controller),

133 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
134 directly, so you need some additional software which knows how to
135 talk to these devices using the SCSI protocol:
136
137 For scanners, look at SANE (<http://www.sane-project.org/>). For CD
138 writer software look at Cdrtools
139 (<http://cdrecord.berlios.de/private/cdrecord.html>)
140 and for burning a "disk at once": CDRDAO
141 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
142 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
143 For other devices, it's possible that you'll have to write the

193
194 If you say Y here, no logging output will appear by default, but you
195 can enable logging by saying Y to "/proc file system support" and
196 "Sysctl support" below and executing the command
197
198 echo <bitmask> > /proc/sys/dev/scsi/logging_level
199
200 where <bitmask> is a four byte value representing the logging type
201 and logging level for each type of logging selected.
202
203 There are a number of logging types and you can find them in the
204 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
205 are also described in that file and they determine the verbosity of
206 the logging for each logging type.
207
208 If you say N here, it may be harder to track down some types of SCSI
209 problems. If you say Y here your kernel will be somewhat larger, but
210 there should be no noticeable performance impact as long as you have

292 SCSI requests and responses over a TCP/IP network between the host
293 (the "initiator") and "targets". Architecturally, the iSCSI driver
294 combines with the host's TCP/IP stack, network drivers, and Network

1034 ---help---
1035 "Tagged command queuing" is a feature of SCSI-2 which improves
1036 performance: the host adapter can send several SCSI commands to a
1037 device's queue even if previous commands haven't finished yet.
1038 Because the device is intelligent, it can optimize its operations
1039 (like head positioning) based on its own request queue. Some SCSI
1040 devices don't implement this properly; if you want to disable this
1041 feature, enter 0 or 1 here (it doesn't matter which).
1042
1043 The default value is 8 and should be supported by most hard disks.
1044 This value can be overridden from the boot command line using the
1045 'tags' option as follows (example):
1046 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1047 4, set queue depth to 16 for target 2 and target 3 on controller 0
1048 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1049
1050 The normal answer therefore is to go with the default 8 and to use
1051 a boot command line option for devices that need to use a different
1052 command queue depth.
1053
1054 There is no safe option other than using good SCSI devices.

1061 This option allows you to specify the maximum number of commands
1062 that can be queued to any device, when tagged command queuing is
1063 possible. The default value is 32. Minimum is 2, maximum is 64.
1064 Modern hard disks are able to support 64 tags and even more, but
1065 do not seem to be faster when more than 32 tags are being used.
1066
1067 So, the normal answer here is to go with the default value 32 unless
1068 you are using very large hard disks with large cache (>= 1 MB) that
1069 are able to take advantage of more than 32 tagged commands.
1070

1077 ---help---
1078 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1079 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1080 are respectively the maximum data transfer rates in mega-transfers
1081 per second for each class. For example, a FAST-20 Wide 16 device is
1082 able to transfer data at 20 million 16 bit packets per second for a
1083 total rate of 40 MB/s.
1084
1085 You may specify 0 if you want to only use asynchronous data
1086 transfers. This is the safest and slowest option. Otherwise, specify
1087 a value between 5 and 80, depending on the capability of your SCSI
1088 controller. The higher the number, the faster the data transfer.
1089 Note that 80 should normally be ok since the driver decreases the
1090 value automatically according to the controller's capabilities.
1091
1092 Your answer to this question is ignored for controllers with NVRAM,
1093 since the driver will get this information from the user set-up. It
1094 also can be overridden using a boot setup option, as follows
1095 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1096 for FAST-20 synchronous data transfer (20 mega-transfers per
1097 second).
1098
1099 The normal answer therefore is not to go with the default but to
1100 select the maximum value 80 allowing the driver to use the maximum
1101 value supported by each controller. If this causes problems with
1102 your SCSI devices, you should come back and decrease the value.
1103
1104 There is no safe option other than using good cabling, right
1105 terminations and SCSI conformant devices.

1112 device of yours to not support properly the target-disconnect
1113 feature. In that case, you would say Y here. In general however, to
1114 not allow targets to disconnect is not reasonable if there is more
1115 than 1 device on a SCSI bus. The normal answer therefore is N.
