Mark,
The iocnum may be greater than 0 (especially if you have
other MPT Fusion HBAs (any kind) in that computer).
Have a look in the log around where the mptsas driver
is registered and look for the string "ioc". The number
following "ioc" is what you need. If you find "ioc3" then
try:

 ./smp_discover -p 12 -s 0x500508b300a27a2f /dev/mptctl,3

To verify that expander SAS address, try this:
  find /sys -name "sas_device:expander*"
cd to any directory found and try "cat sas_address".


BTW there is a smp_utils version 0.92 beta at
http://www.torque.net/sg
the error messages are somewhat clearer.
