That used to be the case prior to Solaris 10 Update 1.

Since S10u1 the supported way of turning on MPxIO is
to run the command 

# /usr/sbin/stmsboot -e


If you manually edit /kernel/drv/fp.conf or /kernel/drv/fp.conf
to change the mpxio-disable property, you *must* also run 

# /usr/sbin/stmsboot -u


Please see stmsboot(1m) for more details.
