[Veritas-bu] Mismatch between sgscan output & st.conf entry?

No - I'm suggesting that the output from sgscan (which I think is returning
the vendor ID string) might have to be a dead-on match with the st.conf
first field (Vendor ID) information - that this is the key-value in the
lookup of the additional setup parameters farther down in the st.conf file.

Right, but are you suggesting then, that sgscan will read from st.conf, 
only if the drives in question are non-DLT? Perhaps, I'm 
misunderstanding something.
