Check out two files in /kernel/drv, st.conf and sgen.conf.
The st.conf file as supplied does not look at lun's > 0.
I think the end of the st.conf file looks like this as supplied.
#---------------------------------------------------------------
name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=1 lun=0;
name="st" class="scsi" target=2 lun=0;
name="st" class="scsi" target=3 lun=0;
name="st" class="scsi" target=4 lun=0;
name="st" class="scsi" target=5 lun=0;
name="st" class="scsi" target=6 lun=0;
#
# In case there are wide tape drives, one can use these targets
#
#name="st" class="scsi" target=8 lun=0;
#name="st" class="scsi" target=9 lun=0;
#name="st" class="scsi" target=10 lun=0;
#name="st" class="scsi" target=11 lun=0;
#name="st" class="scsi" target=12 lun=0;
#name="st" class="scsi" target=13 lun=0;
#name="st" class="scsi" target=14 lun=0;
#name="st" class="scsi" target=15 lun=0;
Note, even the higher numbered scsi targets are not looked at.
If you know your scsi target, say 5 like mine, add a line like:
name="st" class="scsi" target=5 lun=1;
I think the only problem with adding more lines or uncommenting
existing lines is slightly slower boot times.
The sgen.conf file has similar lines that may need
uncommenting or editing. And you may need to add
something like this from my edited sgen.conf:
#####
# Added by jhl
#####
device-type-config-list="changer";
inquiry-config-list= "HP", "HP DDS-3 4mm DAT loader",
"HP", "C1557A";
The strings are what is identified during boot and
can be seen with a prtconf -??? sorry, forget the
options.
This would give you devices under /dev/scsi/???,
where ??? might be changer or sequential.
After the changes, you will need to do a reconfigure
reboot. Or, devfsadm might work without the reboot.
