.Sh NAME
|
|
.Nm isp
|
|
.Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
|
|
.Sh SYNOPSIS
|
|
.Cd "device isp"
|
|
.Pp
|
|
For one or more SCSI busses:
|
|
.Cd device scbus0
|
|
.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) are also supported.
|
|
Command tagging is
|
|
supported for all (in fact,
|
|
.Tn FibreChannel
|
|
requires tagging).
|
|
Fabric support is enabled by default (but may
|
|
be contingent upon the correct firmware being loaded).
|
|
.Sh FIRMWARE
|
|
Firmware is now available if the
|
|
.Xr ispfw 4
|
|
module is loaded during bootstrap (q.v.).
|
|
.Pp
|
|
It is very 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 for NASA/Ames Research Center.
|
|
.Sh BUGS
|
|
The driver currently ignores some NVRAM settings.
|
|
.Pp
|
|
The driver currently does not do error recovery for timed out commands
|
|
very gracefully.
|
|
.Pp
|
|
Target mode support is not completely debugged 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).
|
|
.Pp
|
|
Sometimes, when booting, the driver gets stuck waiting for the
|
|
Fibre Channel f/w to tell it that the loop port database is ready,
|
|
or waiting for a good loop to be seen (this does not yet support
|
|
booting without being connected to a fibre channel device).
|
|
To
|
|
unwedge the system, unplug and replug the fibre channel connection,
|
|
or otherwise cause a LIP (Loop Initialization Primitive sequence)-
|
|
this will kick the f/w into getting unstuck.
|
|
.Pp
|
|
QLogic 2322 support is limited to platforms where the BIOS can
|
|
enable firmware as there is no code yet to do the 3 stage loading
|
|
for 2322 firmware.
