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

  89. ---help---
  90. The OnStream SC-x0 SCSI tape drives cannot be driven by the
  91. standard st driver, but instead need this special osst driver and
  92. use the /dev/osstX char device nodes (major 206). Via usb-storage,
  93. you may be able to drive the USB-x0 and DI-x0 drives as well.
  94. Note that there is also a second generation of OnStream
  95. tape drives (ADR-x0) that supports the standard SCSI-2 commands for
  96. tapes (QIC-157) and can be driven by the standard driver st.
  97. For more information, you may have a look at the SCSI-HOWTO
  98. <http://www.tldp.org/docs.html#howto> and
  99. <file:Documentation/scsi/osst.txt> in the kernel source.
  100. More info on the OnStream driver may be found on
  101. <http://sourceforge.net/projects/osst/>
  102. Please also have a look at the standard st docu, as most of it
  103. applies to osst as well.

  753. In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
  754. are assigned to the drive letters, starting with the lowest SCSI-id
  755. (physical number -- pun) to be drive C:, as seen from DOS and
  756. similar operating systems. When looking into papers describing the
  757. ANSI-SCSI-standard, this assignment of drives appears to be wrong.
  758. The SCSI-standard follows a hardware-hierarchy which says that id 7
  759. has the highest priority and id 0 the lowest. Therefore, the host
  760. adapters are still today everywhere placed as SCSI-id 7 by default.
  761. In the SCSI-standard, the drive letters express the priority of the
  762. disk. C: should be the hard disk, or a partition on it, with the
  763. highest priority. This must therefore be the disk with the highest
  764. SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
  765. original definition of the SCSI-standard as also industrial- and
  766. process-control-machines, like VME-CPUs running under realtime-OSes
  767. (e.g. LynxOS, OS9) do.
  768. If you like to run Linux on your MCA-machine with the same
  769. assignment of hard disks as seen from e.g. DOS or OS/2 on your
  770. machine, which is in addition conformant to the SCSI-standard, you
  771. must say Y here. This is also necessary for MCA-Linux users who want
  772. to keep downward compatibility to older releases of the
  773. IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
  774. June 1997).
  775. If you like to have the lowest SCSI-id assigned as drive C:, as
  776. modern SCSI-BIOSes do, which does not conform to the standard, but
  777. is widespread and common in the PC-world of today, you must say N

  784. However, some devices exist, like special-control-devices,
  785. SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
  786. not reset when switched on. If you say Y here, each device connected
  787. to your SCSI-bus will be issued a reset-command after it has been
  788. probed, while the kernel is booting. This may cause problems with
  789. more modern devices, like hard disks, which do not appreciate these
  790. reset commands, and can cause your system to hang. So say Y only if

  1085. ---help---
  1086. "Tagged command queuing" is a feature of SCSI-2 which improves
  1087. performance: the host adapter can send several SCSI commands to a
  1088. device's queue even if previous commands haven't finished yet.
  1089. Because the device is intelligent, it can optimize its operations
  1090. (like head positioning) based on its own request queue. Some SCSI
  1091. devices don't implement this properly; if you want to disable this
  1092. feature, enter 0 or 1 here (it doesn't matter which).
  1093. The default value is 8 and should be supported by most hard disks.
  1094. This value can be overridden from the boot command line using the
  1095. 'tags' option as follows (example):
  1096. 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
  1097. 4, set queue depth to 16 for target 2 and target 3 on controller 0
  1098. and set queue depth to 10 for target 0 / lun 2 on controller 1.
  1099. The normal answer therefore is to go with the default 8 and to use
  1100. a boot command line option for devices that need to use a different
  1101. command queue depth.
  1102. There is no safe option other than using good SCSI devices.

  1111. Modern hard disks are able to support 64 tags and even more, but
  1112. do not seem to be faster when more than 32 tags are being used.
  1113. So, the normal answer here is to go with the default value 32 unless
  1114. you are using very large hard disks with large cache (>= 1 MB) that
  1115. are able to take advantage of more than 32 tagged commands.
  1116. There is no safe option and the default answer is recommended.

  1122. The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
  1123. rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
  1124. are respectively the maximum data transfer rates in mega-transfers
  1125. per second for each class. For example, a FAST-20 Wide 16 device is
  1126. able to transfer data at 20 million 16 bit packets per second for a
  1127. total rate of 40 MB/s.
  1128. You may specify 0 if you want to only use asynchronous data
  1129. transfers. This is the safest and slowest option. Otherwise, specify
  1130. a value between 5 and 80, depending on the capability of your SCSI
  1131. controller. The higher the number, the faster the data transfer.
  1132. Note that 80 should normally be ok since the driver decreases the
  1133. value automatically according to the controller's capabilities.
  1134. Your answer to this question is ignored for controllers with NVRAM,
  1135. since the driver will get this information from the user set-up. It
  1136. also can be overridden using a boot setup option, as follows
  1137. (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
  1138. for FAST-20 synchronous data transfer (20 mega-transfers per
  1139. second).
  1140. The normal answer therefore is not to go with the default but to
  1141. select the maximum value 80 allowing the driver to use the maximum
  1142. value supported by each controller. If this causes problems with
  1143. your SCSI devices, you should come back and decrease the value.
