Welcome.
Port multiplier support is recent, so you will need to start with a
later build.
I don''t think 2009.06 had any port multiplier support. You will want
to upgrade
to a later dev release, like b125 -- use the dev repository.

The location of the messages file is set in the syslog.conf. For
Solaris/SunOS, it has been /var/adm/messages since a decade before
Linux existed. Perhaps there should be a trivia question to answer
who decided /var/adm vs /var/log... BSD? :-)

It can be useful. Also know that the dmesg command shows the abbreviated
list. You will also want to know about cfgadm, which is useful for
checking
the status of removable devices.
