There goes that idea... :)
So, your HBA's can see the LUNs, and cfgadm has identified them as tape
devices. It seems like it's just devfs that isn't getting updated
correctly... A couple other things to consider:
Are there device files for these drives under /devices? find /devices
| grep st.*cbn$
Are there entries in /etc/path_to_inst for these new tape drives?
grep st /etc/path_to_inst
If the /devices files exist, then I believe the st driver is doing it's
thing. If there are no entries in path_to_inst then the devfs stuff is
failing, if the entries are there, then I don't know what to say...
You could try re-building path_to_inst, but Sun support would probably
be your best bet.

Thanks again for the thoughts, although I checked this earlier today.
I've got 108725-26 installed.
-27 is the latest, pertaining to HP LTO-4 drives.
The patch is one level down, but has the "IBM Ultrium Gen 3 LTO" in the
st driver.
strings /kernel/drv/st | grep IBM
IBM ULTRIUM-TD4
IBM ULT3580-TD4
IBM ULTRIUM-TD3
IBM ULT3580-TD3
IBM ULTRIUM-TD2
IBM ULT3580-TD2
IBM ULTRIUM-TD1

IBM Ultrium Gen 3 LTO
