--- Comment #3 from Peter Eriksson <pen@lysator.liu.se> ---
Did some more testing today. Attached one of the new D6020 disk cabinets (w=
ith
70 SAS drives) to our test server. It looks like the CISS driver does see a=
ll
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)
