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. Doug Gilbert
