My guess is that you need to add the WWN to the st.conf...  Something like this:

name="st" class="scsi" target=c0tw500308c00189780al1;

Do that for each drive and then reload the st driver...

modinfo -i |grep st
modunload -i (number of st driver)
devfsadm -i st

That ought to clear it up.

One other possibility is to run the /usr/openv/volmgr/bin/sg.build
command and have it build the sg.conf entries.  Then, just change the
'name="sg"' to be name="st" and put that in st.conf.
