There are some problem reports possibly related to the new driver use of multiple interrupts on older cards. Hopefully this allow to workaround them. MFC after: 1 week Sponsored by: iXsystems, Inc.

.Sh NAME
|
|
.Nm isp
|
|
.Nd Qlogic based SPI 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"
|
|
.Cd "device ispfw"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following lines in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
isp_load="YES"
|
|
ispfw_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
This driver provides access to
|
|
.Tn SPI
|
|
or
|
|
.Tn FibreChannel
|
|
SCSI devices.
|
|
.Pp
|
|
SPI supports initiator mode for Ultra SCSI and wide mode transactions for
|
|
.Tn SCSI ,
|
|
Ultra2 LVD (1080, 1280), and Ultra3 LVD (10160, 12160).
|
|
.Pp
|
|
Fibre Channel supports initiator and target modes of FCP SCSI profile,
|
|
utilizing Class 3 and Class 2 (2200 and later) connections.
|
|
Support is available for Public and Private loops, Point-to-Point
|
|
and Fabric connections.
|
|
.Pp
|
|
FC-Tape is supported on 4Gb (2400) and newer controllers.
|
|
FC-Tape is highly recommended for connections to tape drives that support
|
|
it.
|
|
It encompasses four elements from the T-10 FCP-4 specification:
|
|
.Bl -bullet -offset indent
|
|
.It
|
|
Precise Delivery of Commands
|
|
.It
|
|
Confirmed Completion of FCP I/O Operations
|
|
.It
|
|
Retransmission of Unsuccessfully Transmitted IUs
|
|
.It
|
|
Task Retry Identification
|
|
.El
|
|
.Pp
|
|
Together these features allow for link level error recovery with tape
|
|
devices.
|
|
Without it, an initiator cannot, for instance, tell whether a tape write
|
|
command that has timed out resulted in all, part or none of the data going to
|
|
the tape drive.
|
|
FC-Tape is automatically enabled when connecting controller that supports
|
|
it to a target that supports it.
|
|
It may be disabled using configuration and hint options described below.
|
|
.Sh FIRMWARE
|
|
Firmware loading is supported if the
|
|
.Xr ispfw 4
|
|
module is loaded.
|
|
It is 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.
|
|

|
|
to use, overriding the value in NVRAM for the card.
|
|

recommended that you set this value to non-zero.
|
|
.It Va hint.isp. Ns Ar N Ns Va .role
|
|
A hint to define default role for isp instance (0 -- none, 1 -- target,
|
|
2 -- initiator, 3 -- both).

.Sh SYSCTL OPTIONS
|
|
.Bl -tag -width indent
|
|
.It Va dev.isp. Ns Ar N Ns Va .loop_down_limit
|
|
This value says how long to wait in seconds after loop has gone down before
|
|
giving up and expiring all of the devices that were visible.
|
|
The default is 300 seconds (5 minutes).
|
|
A separate (nonadjustable) timeout is used when
|
|
booting to not stop booting on lack of FC connectivity.
|
|
.It Va dev.isp. Ns Ar N Ns Va .gone_device_time
|
|
This value says how long to wait for devices to reappear if they (temporarily)
|
|
disappear due to loop or fabric events.
|
|

to those devices will simply be held.
|
|
.It Va dev.isp. Ns Ar N Ns Va .use_gff_id
|
|
.It Va dev.isp. Ns Ar N Ns Va .use_gft_id
|
|
Setting those options to 0 allows to disable use of GFF_ID and GFT_ID SNS
|
|
requests during FC fabric scan.
|
|
It may be useful if switch does not implement them correctly,
|
|
preventing some devices from being found.
|
|
Disabling them may cause unneeded logins to ports not supporting target role
|
|
or even FCP at all.
|
|
The default is 1 (enabled).
|
|
.It Va dev.isp. Ns Ar N Ns Va .wwnn
|
|

|
|
.It Va dev.isp. Ns Ar N Ns Va .wwpn

|
The
|
|
.Nm
|
|
driver was written by
|
|
.An Matthew Jacob
|
|
originally for NetBSD at NASA/Ames Research Center.
|
|
Later improvement was done by
|
|
.An Alexander Motin Aq Mt mav@FreeBSD.org .
|
|
.Sh BUGS
|
|
The driver currently ignores some NVRAM settings.
|
|
.Pp
|
|
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.
