ISP(4) BSD Programmer's Manual (SPARC Architecture) ISP(4)NAMEisp - QLogic ISP1000 SBUS to SCSI host bus adapter driver
SYNOPSIS
isp* at sbus? slot ? offset ?
DESCRIPTION
The isp driver is a software interface to the QLogic ISP1000 series of
SBUS to Small Computer Systems Interface (SCSI) host bus adapters.
The isp driver is designed to be used as a machine-dependent back end for
machine-independent SCSI pseudo-devices (see sd(4), sg(4), st(4)).
BOOT PARAMETERS
There are now parameters which are configurable from boot(8) with the
-parm command. Typically these commands would be added to boot.default(5)
though they can be set at the ``boot:'' prompt.
Many of the parameters take as an argument one or more target ids. The
following are permissible arguments to these parameters:
t0 target 0.
target0 target 0.
t1 target 1.
target1 target 1.
t2 target 2.
target2 target 2.
.
.
.
t14 target 14
target14 target 14
t15 target 15
target15 target 15
all targets 0 through 15
none no targets
The following parameters take a list of target specifiers as an argu-
ment(s):
single_lun
For these targets only look at lun 0.
-parm isp* single_lun=none #default
-parm isp* single_lun=all
skip_targets
These targets will not be probed at boot. Examples:
-parm isp* skip_targets=none #default
-parm isp0 skip_targets=target5 #Don't probe target 5
tags These targets will use tag queueing if supported by the
target. See sd(4) for caveats on its use. Examples:
-parm isp* tags=none #default
-parm isp1 tags=all-t1 #all but target 1
The following parameter takes a numeric value as an argument:
reset_delay
This is used to control the number of seconds of delay
which is inserted after the SCSI bus is reset at boot time.
-parm isp* reset_delay=5 #default
-parm isp* reset_delay=1 #1 second reset delay
-parm isp* reset_delay=0 #no delay after reset
