23 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
24 any other SCSI device under Linux, say Y and make sure that you know
25 the name of your SCSI host adapter (the card inside your computer
26 that "speaks" the SCSI protocol, also called SCSI controller),
27 because you will be asked for it.
28
29 You also need to say Y here if you have a device which speaks
30 the SCSI protocol. Examples of this include the parallel port
31 version of the IOMEGA ZIP drive, USB storage devices, Fibre
93c164af 32 Channel, and FireWire storage.

162 directly, so you need some additional software which knows how to
163 talk to these devices using the SCSI protocol:
164
631dd1a8 165 For scanners, look at SANE (<http://www.sane-project.org/>). For CD

168 and for burning a "disk at once": CDRDAO
169 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
170 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
171 For other devices, it's possible that you'll have to write the

231 There are a number of logging types and you can find them in the

233 are also described in that file and they determine the verbosity of
234 the logging for each logging type.

318 The iSCSI Driver provides a host with the ability to access storage
319 through an IP network. The driver uses the iSCSI protocol to transport
320 SCSI requests and responses over a TCP/IP network between the host
321 (the "initiator") and "targets". Architecturally, the iSCSI driver
322 combines with the host's TCP/IP stack, network drivers, and Network
323 Interface Card (NIC) to provide the same functions as a SCSI or a
324 Fibre Channel (FC) adapter driver with a Host Bus Adapter (HBA).

1112 ---help---
1113 "Tagged command queuing" is a feature of SCSI-2 which improves
1114 performance: the host adapter can send several SCSI commands to a
1115 device's queue even if previous commands haven't finished yet.
1116 Because the device is intelligent, it can optimize its operations
1117 (like head positioning) based on its own request queue. Some SCSI
1118 devices don't implement this properly; if you want to disable this
1119 feature, enter 0 or 1 here (it doesn't matter which).
1120
1121 The default value is 8 and should be supported by most hard disks.
1122 This value can be overridden from the boot command line using the
1123 'tags' option as follows (example):
1124 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1125 4, set queue depth to 16 for target 2 and target 3 on controller 0
1126 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1127
1128 The normal answer therefore is to go with the default 8 and to use
1129 a boot command line option for devices that need to use a different
1130 command queue depth.
1131
1132 There is no safe option other than using good SCSI devices.

1142 Modern hard disks are able to support 64 tags and even more, but
1143 do not seem to be faster when more than 32 tags are being used.
1144
1145 So, the normal answer here is to go with the default value 32 unless
1146 you are using very large hard disks with large cache (>= 1 MB) that
1147 are able to take advantage of more than 32 tagged commands.

1156 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer

1159 per second for each class. For example, a FAST-20 Wide 16 device is
1160 able to transfer data at 20 million 16 bit packets per second for a
1161 total rate of 40 MB/s.
1162
1163 You may specify 0 if you want to only use asynchronous data
1164 transfers. This is the safest and slowest option. Otherwise, specify
1165 a value between 5 and 80, depending on the capability of your SCSI
1166 controller. The higher the number, the faster the data transfer.
1167 Note that 80 should normally be ok since the driver decreases the
1168 value automatically according to the controller's capabilities.
1169
1170 Your answer to this question is ignored for controllers with NVRAM,
1171 since the driver will get this information from the user set-up. It
1172 also can be overridden using a boot setup option, as follows
1173 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1174 for FAST-20 synchronous data transfer (20 mega-transfers per
1175 second).
1176
1177 The normal answer therefore is not to go with the default but to
1178 select the maximum value 80 allowing the driver to use the maximum
1179 value supported by each controller. If this causes problems with
1180 your SCSI devices, you should come back and decrease the value.
