The man pages for the Trusted Solaris environment reside in three different directories, which need to be included in your MANPATH environment variable:
/usr/man
/usr/openwin/man
/usr/dt/man
The MANPATH variable can be set individually by users in their shell initialization files or globally by administrators in site-wide shell initialization files in /etc/skel (or alternate skeleton directory) for all users. To set the MANPATH variable, type:
setenv MANPATH="/usr/dt/man:/usr/openwin/man:/usr/man:$MANPATH"
To check a system's current MANPATH setting, type:
echo $MANPATH
This should display the three paths mentioned above and any other paths to man pages at your site.
