Solaris 8 and 9 were pretty easy. To restart the service (which wasn't one) after you've mucked about in /etc/auto_master &c.:
# /etc/init.d/autofs stop; /etc/init.d/autofs start
Solaris 10 is different. The init script is no longer there, and autofs has become a service. To figure out if is running and to (re)start it after doing what you need to do, follow this sequence:
# svcs | grep auto legacy_run 14:14:53 lrc:/etc/rc2_d/S72autoinstall online 9:51:27 svc:/system/filesystem/autofs:default # svcadm -v restart svc:/system/filesystem/autofs:default Action restart set for svc:/system/filesystem/autofs:default.cd to your newly mounted dirs and away you go.
