.Sh NAME
|
|
.Nm isp
|
|
.Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device scbus"
|
|
.Cd "device isp"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
isp_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
This driver provides access to
|
|
.Tn SCSI
|
|
or
|
|
.Tn FibreChannel
|
|
devices.
|
|
.Pp
|
|
SCSI features include support for Ultra SCSI and wide mode transactions
|
|
for
|
|
.Tn SCSI ,
|
|
Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the
|
|
ISP12160).
|
|
.Pp
|
|
Fibre Channel support uses FCP SCSI profile for
|
|
.Tn FibreChannel .
|
|
and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
|
|
3 only, minor patches to the Qlogic 2200 to force Class 2 mode).
|
|
Support is available for Public and Private loops, and for
|
|
point-to-point connections (Qlogic 2200 only).
|
|
The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432)
|
|
are also supported.
|
|
Command tagging is
|
|
supported for all (in fact,
|
|
.Tn FibreChannel
|
|
requires tagging).
|
|
Fabric support is enabled by default for other than 2100 cards.
|
|
Fabric
|
|
support for 2100 cards has been so problematic and these cards are so
|
|
old now that it is just not worth your time to try it.
|
|
.Sh FIRMWARE
|
|
Firmware is available if the
|
|
.Xr ispfw 4
|
|
module is loaded during bootstrap (q.v.).
|
|
.Pp
|
|
It is
|
|
.Ar strongly
|
|
recommended that you use the firmware available
|
|
from
|
|
.Xr ispfw 4
|
|
as it is the most likely to have been tested with this driver.
|
|
.Sh HARDWARE

.Sh AUTHORS
|
|
The
|
|
.Nm
|
|
driver was written by Matthew Jacob originally for NetBSD at
|
|
NASA/Ames Research Center.
|
|
.Sh BUGS
|
|
The driver currently ignores some NVRAM settings.
|
|
.Pp
|
|
Target mode support is not completely reliable yet.
|
|
It works reasonably
|
|
well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
|
|
does not yet work for the other cards (due to last minute unannounced
|
|
changes in firmware interfaces).
