--- Comment #3 from Peter Eriksson <pen@lysator.liu.se> ---
Did some more testing today. Attached one of the new D6020 disk cabinets (with
70 SAS drives) to our test server. It looks like the CISS driver does see all
70 drives, but some way up to the CAM layer 16 of them gets lost :-)

# cciss_vol_status -V /dev/ciss0 | egrep 1200 | wc -l
      70

# camcontrol devlist | egrep 1200 | wc -l
      48

(Full output from cciss_vol_status & camcontrol added as attachments)
