.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).
|
|
Command tagging is supported for all (in fact,
|
|
.Tn FibreChannel
|
|
requires tagging).

.Sh CONFIGURATION OPTIONS
|
|
.Pp
|
|
General configuration options for all adapters include:
|
|
.sp
|
|
.Cd options SCSI_ISP_NO_FWLOAD_MASK
|
|
.Cd options SCSI_ISP_NO_NVRAM_MASK
|
|
.Cd options SCSI_ISP_PREFER_MEM_MAP
|
|
.sp
|
|
for which the option value is a bit mask of units for which you want this
|
|
option to apply.
|
|
The options are, respectively, for not loading new firmware
|
|
at startup, ignoring card NVRAM settings, and preferring memory mapped
|
|
versus I/O port PCI access methods.
|
|
.Pp
|
|
Poorly debugged and prototype target mode support may be enabled with the
|
|
.sp
|
|
.Cd options ISP_TARGET_MODE
|
|
.sp
|
|
option.
|
|
.Pp
|
|
Configuration options that define whether downloadable firmware should be
|
|
compiled into the driver are:
|
|
.sp
|
|
.Cd options ISP_COMPILE_1020_FW
|
|
.Cd options ISP_COMPILE_1080_FW
|
|
.Cd options ISP_COMPILE_12160_FW
|
|
.Cd options ISP_COMPILE_2100_FW
|
|
.Cd options ISP_COMPILE_FW
|
|
.sp
|
|
The above options either select which board's f/w you wish to compile in,
|
|
or for the last, to select all.
|
|
.Pp
|
|
Configuration options specific to Fibre Channel Cards are:
|
|
.sp
|
|
.Cd options SCSI_ISP_FCDUPLEX
|
|
.Cd options SCSI_ISP_FABRIC
|
|
.Cd options SCSI_ISP_SCCLUN
|
|
.Cd options SCSI_ISP_WWN
|
|
.sp
|
|
The first option is a bit mask of units for which you want to enable full
|
|
duplex mode.
|
|
This typically would only make sense if fabric support is
|
|
enabled and you are directly connected to a switch.
|
|
The second defines whether Fibre Channel Fabric support should be enabled.
|
|
The third defines whether whether the first level SCC lun support should
|
|
be enabled- this converts the normal 16 Logical Unit support to support for
|
|
65536 Logical Units.
|
|
The last option should be a string that defines an
|
|
overriding World Wide Node Name (WWNN) should you wish to override NVRAM
|
|
settings.
|
|
It is recommended that you compile in firmware if you select
|
|
any of these options.
|
|
.Sh BOOT OPTIONS
|
|
.Pp
|
|
Many of the above options are switchable by setting values in the loader
|
|
configuration file (see the
|
|
.Xr loader 8
|
|
manual page). They are:
|
|
.sp
|
|
.Bl -tag -width "isp_no_fwload" -compact
|
|
.It isp_disable
|
|
A bit mask of units to skip configuration for.
|
|
.It isp_mem_map
|
|
A bit mask of units to use PCI Memory space instead of I/O
|
|
space access for.
|
|
.It isp_io_map
|
|
A bit mask of units to use PCI I/O space instead of Memory
|
|
space access for.
|
|
.It isp_no_fwload
|
|
A bit mask of units that you wish to skip firmware download for.
|
|
.It isp_fwload
|
|
A bit mask of units that you wish to *do* firmware download for.
|
|
.It isp_no_nvram
|
|
A bit mask of units that you wish to ignore board NVRAM settings for.
|
|
.It isp_nvram
|
|
A bit mask of units that you wish to specifically use board NVRAM settings for.
|
|
.It isp_fcduplex
|
|
A bit mask of units that you wish to specifically to set into full
|
|
duplex mode.
|
|
.It isp_no_fcduplex
|
|
A bit mask of units that you wish to specifically to not set into full
|
|
duplex mode.
|
|
.It isp_wwn
|
|
This should be the full 64 bit World Wide Node Name you would like to
|
|
use, overriding the value in NVRAM for the card.
|
|
.It isp_debug
|
|
This is a driver debug level- meaningful from 0 through 7.
|
|
.It isp_tdebug
|
|
This is a driver target mode debug level- meaningful from 0 through 5.
|
|
.El
|
|
.Sh BUGS
|
|
The driver currently ignores some NVRAM settings.
|
|
.Pp
|
|
The driver currently doesn't do error recovery for timed out commands
|
|
very gracefully.
|
|
.Pp
|
|
Fabric support isn't very well debugged yet, and with some switches,
|
|
fails to work as well as it should because the driver uses the GET ALL NEXT
|
|
Simple Name Server subcommand which some switches don't handle as well
|
|
as they should.
|
|
.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.
|
|
In this case you'll
|
|
see an announcement that the loop state has a value of 0x1.
|
|
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.
