PCI I/O Board Installation and Component Replacement • April 1998
1. Add this entry to the
/etc/system
file to disable UltraSCSI for the system:
2. Add this entry to the
/kernel/drv/isp.conf
file:
The line
scsi-options=0x7f8
enables the controller.
The line
target0-scsi-options=0x3f8;
disables target 0.
A.3
ISP
Man Page
The
isp
man page provides help on determining the physical path name and using
prtconf
to verify what speed is allowed on the disks. The section on path names
includes this information:
set scsi_options=0x3f8
name="isp" parent="
/pci@1f,2000/pci@1
"
unit-address="
4
"
scsi-options=0x7f8
target
0
-scsi-options=0x3f8;
PCI Bus
The above example is more specific to the ISP controller on SBus.
To achieve the same setting of scsi-options on a PCI machine,
create a file called /kernel/drv/isp.conf and add the following
entries.
name="isp" parent="/pci@1f,2000/pci@1"
unit-address="4"
scsi-options=0x178
target3-scsi-options=0x58 scsi-initiator-id=6;
The physical pathname of the parent can be determined using the
/devices tree or following the link of the logical device name:
example# ls -l /dev/rdsk/c4t3d0s0
lrwxrwxrwx
1 root root 58 Jun 20 23:48 /dev/rdsk/ c4t3d0s0 ->
../../devices/pci@1f,2000/pci@1/SUNW,isptwo@4/sd@3,0:a,raw
